Sub Solution Synthetic Urine 2024 Review: Still The Best?

sub solution synthetic urine to pass drug test fast

We all know that synthetic urine is pretty much the surest way of passing a drug test by mimicking the real urine.

The first of the next generation synthetic urine is the popular Sub-Solution synthetic urine. Being able to heat itself to body temperature, Sub-Solution is what most illegal drug users use when it comes to a urine drug test.

Real urine (left) vs. Sub-Solution synthetic urine (right). Can you tell the difference? Drug testing labs sure can’t.

What is more, Sub-Solution retained the 2023 title as the best synthetic urine in the 2024 synthetic urine comparison as well.

Sub-Solution is the industry standard and has scored the No. 1 synthetic urine award for passing a drug test in 2024 synthetic urine review (it usually gets a 5-star review by the users).

Sub-Solution Reviews

You should really check the story about the guy who also did thorough research on the best synthetic urines and choose the Sub Solution – here is his post on 420magazine.

Basically all other synthetic urines out there are knock-offs of Sub Solution, but nobody has yet to master the self-heating property the Clear Choice Sub Solution has (you have to heat other synthetic urines to body temperature ‘somehow’ so they don’t catch you using synthetic urine in a urine drug test).

Not only does the Sub-Solution by TestNegative has the highest rating and self-healing mechanism, but it is also the only synthetic urine that has been around for more than 10 years. 

That just tells you that people have been buying it for a long time and readily recommended it in order for the company to keep selling it – you can easily buy it here.

What I found most credibly about Sub-Solution synthetic urine is the list of ingredients that the solution consists of.

For example, on the packaging, it clearly states that the powdered urine you get (with a vial for heating and plastic container) contains urea and uric acid. These are the two basic ingredients of urine that every synthetic urine should contain – but the Sub Solution is the only one that is clear about that.

What Is Sub Solution Anyway?

As with any synthetic urine, Clear Choice’s Sub Solution is a solution that closely mimics standard and natural urine. Chemically speaking, it is a complex water solution, containing both organic and inorganic substances – just like real urine does.

Urine helps us eliminate products of cellular metabolism and, of course, THC or any other drugs if present. Sub Solution is chemically speaking exactly the same as natural urine but without the drugs, one might use. Hence it is perfect for passing a drug test – chemically it will test out as perfectly normal urine.

What Is Synthetic Urine Made Of?

Synthetic urine has the same ingredients as urine, in the same proportions and concentration. Urine drug tests measure the content of the most important ingredients – urea, uric acid, and creatinine – as well as pH and specific gravity that come mainly from inorganic components.

For example, here is a study of how much uric acid is in urine – healthy volunteers had a 5.1-7.0 mg/dl concentration of uric acid in urine. This is exactly how much uric acid the best synthetic urine should contain.

To mimic natural urine, synthetic urine – if produced correctly – should be a complex water solution that has about 3 times as many organic substances as inorganic ones (chlorides, phosphates, sulfates and ammonia).

Here are is the ingredients list of what synthetic urine should be made out of:

  1. Urea – 50 to 100 mg/dl of urine.
  2. Uric acid – 5.0 to 7.0 mg/dl.
  3. Creatinine – 35 to 320 mg/dl.
  4. Potassium sulfate (K2SO4) – 1 to 3 g/l.
  5. Sodium sulfate (Na2SO4) – 1 to 3 g/l.
  6. Ammonium phosphate – 0.5 to 1.5 g/l.
  7. Ammonium diphospate – 0.5 to 1.5 g/l.
  8. Calcium chloride (CaCl2) – 0.1 to 0.5 g/l.
  9. Magnesium chloride (MgCl2) – 0.25 to 1 g/l.

The inorganic substances synthetic urine is made out of (point 4-9) are what gives the synthetic urine the same pH and specific gravity as genuine urine.

Urine has a pH of 4 to 10 and a specific gravity between 1.000 and 1.035. As does Sub Solution; in fact, Sub Solution is the best synthetic urine precisely because it has the best balance of organic to inorganic components. You can check out them even in their patent.

Can Synthetic Urine Be Detected In A Drug Test?

If you do everything correctly, synthetic urine can’t be detected by standard drug testing panels. Because ‘fake pee’ so much resembles the natural urine, as far as inorganic, organic content, pH, specific gravity, urea, and so on are concerned, the drug test will detect synthetic urine as normal urine.

There is only one catch, though – low-quality synthetic urine products. As you’ve seen, patented synthetic urine does have exactly the right amount of urea, creatinine and so on. It is quite a long list.

The surest way for synthetic urine to be discovered on a drug test is if somebody uses a low-quality fake pee. There can be several problems with such cheap fake pee products that can be caught on a drug test:

  1. pH is too low. 4 or lower.
  2. Specific gravity is too high. If you put too much low-quality ingredients in a drug test, the specific gravity can spike above 1.050.
  3. Urea or creatinine levels are too low. Cheaper fake pees usually prefer to stay on the low-end range especially when creatinine is concerned (admittedly, it’s cheaper for them to use less). In some cases, creatinine levels can be below 30 mg/dl – too low.
  4. Urine temperature is too low. Very important! Synthetic urine has to be heated up to a body temperature – 90 to 105F. Sub Solution comes with a self-heating mechanism; cheaper urines must be microwaves for about 10 seconds and it’s really hard to hit exactly 90 to 105F with a microwave.

In short, if you use high-quality synthetic urine, these things can’t occur. If you use cheap fake pee, chances are you’re going to be caught on a drug test.

How Do You Keep Sub Solution Urine Warm?

When you giving a urine sample, it has a temperature between 90 and 105 degrees Fahrenheit. Synthetic urine such as Sub Solution should have the same temperature; so how do you warm it up and keep warm?

With other synthetic urines, you have to worry about microwaving it and keeping it close to your body in order not to lose heat. Sub Solution, however, has a patented heat activator – a small vial of lithium chloride (LiCl) that can’t be detected by a drug test.

Here is how you warm up Sub Solution prior to the test:

  1. Mix Sub Solution with water – water temperature should be between 70 to 90F – and prepare 2,3 or 5-ounce synthetic urine solution. Sub Solution contains details instructions on how to do this; it’s easy and simple.
  2. Add the heat activator (little granules in the dark vial) slowly. Shake or stir if needed, and watch the temperature probe.
  3. The attached temperature probe will turn green when the synthetic urine is of body temperature (98 to 102F).
  4. Excess heat activator can be appropriately discarded.

Note: If the temperature is too high, the temperature probe will go ‘red’. Cool the whole solution of synthetic urine down by running tap water on the outside of the container. When it turns green again, the temperature is just right.

You can keep Sub Solution warm be keeping it close to your body (underarm, thigh). It can be there for more than 2 hours while you wait for a drug test.

What Do Users Say About Sub Solution Synthetic Urine?

Honestly having a closed-door test is what you usually get when doing a urine drug test. Mixing up the Sub-Solution is a piece of cake when nobody is watching.

From this Sub-Solution review, we also see that you can warm the solution up yourself is you tuck it up under your breast for an hour. However, the self-heating vial you get with the purchase, you don’t have to warm up for an hour. The vial warms it in seconds. That can be very useful when you’re in a cabin at Quest.

Is Sub-Solution A Life-Saver?

He has the truth of it through – all the guys on the street use synthetic urine and Sub Solution is pretty much the most widely known in the stoner’s world. 

Negative Review of Sub-Solution?

Whenever you have a popular product, you’ll have some negative reviews as well.

This is the same thing that was found in the synthetic urine 2024 comparison. The Sub works like a charm but it is pricey. However, when trying to do a THC detox or pass a urine drug test in 24 hours with synthetic urine, you really shouldn’t be looking at pricing. Why?

Because if you buy bad urine, your job is probably on the line. And a job is much more important than a few extra $10 in the wallet.

Average Customer Rating is 4.4/5 Making Sub Solution Highest Rated Synthetic Urine

All in all, the Sub is the highest rated synthetic urine and it’s been around since 2003. It is sold exclusively online and we don’t list where to buy synthetic urine in stores article.

When it comes to buying quality synthetic urine to pass a drug test, the Sub is the thing you get (if you can afford it).

Other synthetic urines might work just as fine (you’ll just have to heat them up somehow) and will cost a bit less but if you want to have a guaranteed ‘THC negative’ on your drug test, the Sub-Solution is the first choice.

You can buy the Sub-Solution here even a day before a drug test.

All the luck to you guys!

Does Synthetic Urine Work With Drug Tests? (2024 Updated)

Even though synthetic urine is the most popular way of passing a urine drug test, we still get a lot of emails with ‘I have a drug test in 2 days, I’m x tall and weigh x pounds, smoked a joint 2 weeks ago, should I use synthetic urine? Does synthetic urine work?’.

To clear the picture and put some common sense thinking into does synthetic urine work for lab drug tests, we did a bit of investigating which uncovered the following conclusions:

Does synthetic urine work for:

  1. Calibrating urinalysis test strips – it was created to check if urine drug tests work properly – YES.
  2. ‘Golden showers’ – synthetic urine does work for that but some people complain about the lack of ‘that unique smell’ – so partly yes.
  3. Passing a urine drug test (the big one everybody wants to know about) – of course, it works if you use it with common sense – so YES.

We focused on the question if synthetic urine works to pass a drug test, even in 2017. From user reviews and, well, our own experience we are quite certain that it works (otherwise it wouldn’t be so frequently used by one-time puffers and true stoners alike to beat a drug test).

What is even more important than knowing if synthetic urine works is which is the best one to use to guarantee you to pass. We’ll go into that but here’s a spoiler – it has everything to do with the right temperature of synthetic urine.

Urinalysis uses sample urine to determine if an individual used drugs in the past month.

How Does Synthetic Urine Work?

Despite synthetic urine being widely used to beat drug tests, it was initially designed to test if urinalysis test strips work consistently or not.

Basically, they mixed together all the things that they measure with a urine test (such as urea and uric acid) to create perfect healthy urine – otherwise known as ‘synthetic urine’. Then they checked if urine test strips will recognize the synthetic urine as perfect healthy urine – and out of 100 tests, 100 test strips told the same. There is no difference between synthetic urine and normal urine.

Of course, when drug testing for employment began, people started using synthetic urine to beat the drug test. Test strips dipped into a cup of normal urine, and the best synthetic urine (2024) shows exactly the same result.

synthetic-urine-vs-real-urine (1)
Real urine (left) vs. synthetic urine (right). Can you tell the difference? Even labs can’t tell them apart.

What makes synthetic urine work is, of course, that it is toxin-free. If you smoked weed in the past few weeks, test strips dipped in your pee will recognize THC and you’ll get ‘THC-positive’ on your medical record. Ups!

Now, if you would put synthetic urine in the cup instead of your urine, the test strips dipped in it would tell the lab techs it’s a healthy urine. Does it include THC? Nope, it’s clean and you get ‘drug-free’ on your medical record. Quite simple, right? That’s the basics of how does synthetic urine work for lab tests.

Let us have a look when synthetic urine doesn’t work:

The Only Case When Synthetic Urine Doesn’t Work For Urine Drug Test

Almost any synthetic urine will show up as a clean healthy urine on the urinalysis test strips. However, there is one case when people don’t pass a drug test when using synthetic urine (and they have to redo the test).

»The Cold Urine« Case

Everybody using common sense will be able to pass a drug test with the right synthetic urine. What some omit is that for synthetic urine to really work, they have to heat it up.

Don’t get me wrong: the test strips and lab results will always be fine as in ‘drug-free’ urine. The only problem is if the lab tech who usually collects the cups of urine picks up your urine sample and it’s cold.

Your own urine would come from your bladder and would have body temperature (about 98-102 F). In order to pass a drug test with synthetic urine, you have to heat it up. If the lab tech will feel that urine temperature is any other than body temperature, he or she will probably know what’s up. And even then, you will only be asked to redo the test – so another urine sample.

Luckily, with a bit of common sense, there is a simple solution to cold urine – just heat it up!

How To Heat Up Synthetic Urine So That It Does Work Every Time

There are actually two options for how to do that – the easy one and the hard one.

I’ll start with the hard one:

Hard Option

Microwave it for 10 seconds and then, somehow, keep it warm. I have to honestly say that because of this technique of heating it up people still ask ‘does synthetic urine work’. Why?

Because sooner or later you’ll find someone who overheated the synthetic urine and the lab tech figured out this molten-lava hot urine couldn’t possibly come from a human being.

how-to-use-microwave-to-get-urine-to-the-right-temperature
How do you microwave synthetic urine exactly to 98-102 F? It’s almost impossible.

We also, of course, have some geniuses who don’t heat it at all and are asked to redo the test again (this time with their urine).

Easy Option

Believe it or not, synthetic urine producers thought about how to easily heat up synthetic urine so that it does work consistently. One actually did figure it out and even patented their formula. Here is the link to the patent, if you’re interested:

The easy heat up comes in a vial containing a special chemical that, when poured into the synthetic urine, heats it up exactly to 98-102F (you even get an indicator that turns green when the urine is in the right temp. range).

The synthetic urine that comes with the self-heat up vial is called Sub-Solution synthetic urine and it’s pretty much the most recommended synthetic urine to use for drug test exactly because of the easy heat-up.

Thus, it is no wonder that ‘The Sub’ won the #1 rank as the best synthetic urine of 2024. Here is the list of top 4 synthetic urines currently on the market:

You’ll Pass A Drug Test With A Bit Of Common Sense (No Worries)

With synthetic urine, a guy flipping burgers at Mcdonald’s or a rocket scientist can pass a drug test. Just don’t be stupid about it – synthetic urine does work but you have to heat it up to exactly the body temperature.

Of course, you can microwave it and risk getting caught, or you can buy Sub-Solution and just pour the vial into the ready-to-go synthetic urine.

Just don’t let that one joint you had a few weeks ago ruin your future, especially because even if weed is legal, the drug testing laws are still enforced and that’s simply irrational.

Synthetic Urine Near You: Online Shops And Store Locator

The most common way of beating a urine drug test is by substituting your urine with synthetic urine.

You can find synthetic urine near you by using the store locator.

However, us stoners who have passed a urine drug test with synthetic urine a couple of times know how important it is to get good synthetic urine.

Where to buy fake pee?

  • In stores near you.
  • Online stores.

When you use it regularly (because your boss tests you once a year) it’s good to know where to buy synthetic urine – in nearby stores or online?

Most of the people I speak to buy synthetic urine online because it’s more discreet (you don’t have to do all the face-to-face buying process as you would do in the store).

That’s why the best synthetic urine of 2024 – Powdered Urine kit – is sold exclusively online and naturally, it’s the one that most of our fellow stoners use. Here is the list of stores that sell it online:

We’ll get to where to buy synthetic urine in your vicinity but since most people buy it online let’s start with how to buy synthetic urine online, shall we?

Where To Buy Synthetic Urine Online? (90%)

Roughly 90% of synthetic urine is sold online and here’s why:

  • Discrete (you don’t need to go to the store and show your face)
  • Quick (same-day shipping)
  • You get the best synthetic urine (the No. 1 synthetic urine is sold exclusively online)

When you buy synthetic urine in-store, you usually buy from the nearest head shop and you buy the one they have (if they have one – in most cases, they, unfortunately, don’t).

The luxury of buying fake pee online is that you can buy from pretty much from anywhere (1-day shipping) and can get the best quality synthetic urine.

As you can see, the synthetic urine that is sold in head shops – Quick Fix – is kind of ok but the clear winner is the Sub-Solution from TestNegative.com (online store).

Sub-Solution (Rated #1 in 2024) Is Available Exclusively Online

As such a large portion of synthetic urine is sold online, it’s obvious to see why ‘The Sub’, as well as a majority of other synthetic urine kits, are only available online.

For some stoners, the best place where to buy synthetic urine would be in a local store but for a company, it’s much easier to sell online from one big storage instead of regularly supplying synthetic urine to 1000s of head stores all over the US.

That being said, the best performing synthetic urine for passing a urine drug test sells their ‘pee’ exclusively online for 13 years now.

There are two reasons why ‘The Sub’ is so popular when it comes to passing a drug test on short notice:

  • Already comes in liquid form (pre-mixed)
  • Has self-heating mechanism (just empty the vial in the synthetic urine and it’ll heat up)

Most of the synthetic urines come in a form of powder and you have to add water and mix them. Not the Sub. What you get is ready-to-be-poured into the test cup right away.

What is even more important is the self-heating mechanism. In order to fool the lab, the urine you present to them must be at about body temperature. Nobody would believe you that you really pissed in the cup if the piss would be cold, right?

People try to warm it out with hands or put in under an armpit and so on. I even once talked to a guy who was sitting on a pouch filled with some cheap synthetic urine for the whole time to keep it warm – now that was a real stoner, mind you.

Why Sub-Solution is such a hit is because of the vial that comes with it. You pour the chemical mixture from the vial in the synthetic pee and it almost ‘magically’ warms up to the body temperature. It’s quite astonishing to see and you might imagine that is it very useful if you’re serious about passing a drug test with synthetic urine.

‘The Sub’ was the first one to introduce the self-heating technology and nobody even came close to it – hence it hits the No. 1 spot for the best synthetic urine every year.

If you really need to pass a drug test and have a guarantee that it’s going to work, you can buy Sub-Solution here:

Self-warming synthetic urine Sub-Solution with heat activator.

I can say for myself that synthetic urine has saved my job (and well, my life I guess) for a couple of times now.

The best thing is that I can smoke right up to the medical examination, use the synthetic pee to pass a drug test and then enjoy a joint just to celebrate my now yearly ritual of getting ‘randomly’ selected for a drug test.

You can also go with the premium Quick Luck synthetic urine; it does cost $100 but it is regularly updated in order to be undetectable.

Where To Buy Synthetic Urine In Stores? (10%)

Because it is well known that synthetic urine is used primarily to pass a drug test (people also use it as a ‘golden shower’ fetish – you know who you are), it’s usually not sold in ordinary stores.

But there are stores that do sell fake pee and you might live near one. You probably know which stores.

»Do head shops sell synthetic urine?«

Some of the bigger ones do. The most likely place where to buy synthetic urine near you is a local head shop. In my experience they usually keep a regular stock of Quick Fix synthetic urine which is ok, I guess, but for me, I like to be sure to pass a urine drug test and just buy the good stuff online.

I would also recommend calling the local head store beforehand and just ask ‘I’m wondering where I can buy synthetic urine – do you guys sell it?’ They’re sure to tell you what’s up.

Synthetic Urine Near Me? (Store Locators)

You can check if there is a head store near you with at https://weedmaps.com/. It’s a cool website app that helps you locate where to buy synthetic urine in stores – of course, they sell weed as well.

For example, if you’re wondering where to buy synthetic pee in Las Vegas, just enter Las Vegas. You know the drill.

So this is where you can buy synthetic urine in stores if you’re are desperate and need it in like 1 hour. However, if you have at least 24 hours before a drug test, you should be wondering where you can buy fake pee online.

I wish the best for all the stoners out there!

How To Keep Urine Warm For Drug Test? (90-102°F)

Ever heard that warm beer tastes like piss? Well, when it comes to drug testing, that’s exactly what you want: pee that feels, tastes, smells and has the same temperatures as natural urine from a human body should have.

The only problem is that the moment urine leaves our body, it starts to cool down (unless you’re in Texas in a 120-degree heatwave). And the first thing the lab tech conducting a drug test of your urine is going to notice is ice-cold urine.

Obviously, we need to learn how to keep urine warm for a drug test if we ever want to pass the lab tech’s temperature check.

We’ll cover 3 best ways of how to keep the temperature of urine high enough to pass a drug test without problems. In the end, I’ll also give you some tips on how to smuggle warm clean urine or, even better, synthetic urine when that dreaded drug test comes along.

The most recommended way to keep your pee warm is the #3 Method (see below). It’s also the most natural one and helps you bring the urine to the drug testing facility the easiest.

What Temperature Should Urine Have To Pass A Drug Test?

Your urine sample should be warm enough for the lab tech to say ‘Hey, that just came out of a human being’. Every lab trains their techs to detect odd urine temperature.

Even the most untrained fool will notice if your urine sample is too hot or too cold.

Too hot means that you’ve left the urine too long in the microwave and too cold means that you obviously didn’t give your own fresh urine (you used synthetic urine, friend’s urine or your own refrigerated urine you’ve been keeping next to milk and eggs for just such an occurrence).

what-happens-when-urine-is-not-the-right-temperature-on-a-drug-test
Too hot urine is usually the result of microwaving urine for too long.

The result, in either case, is the same. The urine sample is not valid because it’s not of adequate temperature.

So before we go over the methods of how to keep urine warm enough for a drug test, let’s answer what should that ideal urine temperature be.

In short, the most optimal temperature of a urine drug test sample is 90-102 degrees Fahrenheit.

That’s not too cold, not too hot, it feels just right and natural.

Alright, here are the best 3 methods of how to prevent the temperature of your urine to fall out of the optimum interval prior to a drug test:

#1 Method: Use Hand Warmers (The Most Questionable One)

I always love how easy keeping urine sounds when somebody brings out the hand warmers.

“You use hand warmers, bro. It’ll keep urine nice and warm.”

Well, will it though?

Hard warmers do keep your pee warm, are cheap and do seem like they can handle the task. They can but you’re really taking a gamble if you think using hand warmers to keep the urine was is a fool-proof system.

The problem that you will always have with hand warmers is that you can never know if the urine that you’re warming up is too hot. I mean, how many times have you physically touched your pee with your hand just to casually try out how that warmth feels?

Can you tell the difference between 100 F urine and 110 F urine?

The lab techs are specially trained to notice that difference but they’re handling cups full of pee all day long. Your hands, however, are not a thermometer.

Don’t get me wrong. You can say that using hand warmers is the best way to keep urine warm but the reality is that if you manage to pass the urine as geniuine it’s not because you’ve nailed down the keeping-pee-warm system.

More often than not, it’s luck.

And when it comes to passing a drug test, you really don’t want to be pressing your luck.

It’s also the most obvious trick to keep your urine warm and the labs bloody well know it.

#2 Method: Just Microwave It For 10 Minutes (Or Maybe Just Don’t?)

Here’s how this scenario of getting your urine up to the temperature and keeping it warm enough to pass a drug test goes:

  1. Put synthetic urine or your urine in the microwave for 10 seconds.
  2. Take it out and present it as urine drug sample in less than 1 hour (or it’ll get too cold).

Whenever I come across this urine warming method, I have so many questions. Like what should the power setting of the microwave be? Or what if there is a waiting line in the lab and it takes more than 1 hours before I can turn in my pee? How do I actually know that the urine is still is the 90-102F temperature zone?

Look at all these microwave settings:

how-to-use-microwave-to-get-urine-to-the-right-temperature

As far as I can see it, the microwave is a useful way to heat up the urine but as far as keeping urine warm is concerned, I don’t see the point.

You can’t really tell if the urine you have on you is warm enough. The only thing you have racing in your mind is that you have to be in there proving this urine you’re carrying around in under an hour.

That’s quite stressful and the last thing you want lab people to read of your face is the sense of sheer panic because of the ticking time bomb.

All in all, the microwave method is good for heating your piss up to the right temperature but not really for constantly keeping it at that temperature interval.

#3 Method: Using Your Own Body Heat (The Most Natural And Fool-Proof Way)

In the end, you can realize that the best way to keep your urine warm for a drug test is by keeping it close to your body.

The urine you’ll submit must have body temperature. And lo and behold! Your body has exactly that right temperature. As a matter of fact, it’s literally called your BODY temperature.

Here are a few points in the right direction because hugging a cup of your urine won’t really cut it:

  1. Stick warmed up urine close to your body – underarm, under the boob, in the crutch, taped to a thigh – for at least 1 hour. That’ll bring the temperature as close as possible to that perfect body temperature.
  2. Use a bag that will closely fit your body. Plastic cup won’t heat up next to your thigh and it will stick out like a sore thumb. Get a flexible bag, if possible.
  3. Even better, buy a specialized incognito kit. The ones that already have 100% clean synthetic urine are the best. Here is the best kit that goes over your stomach (it’s like having a real beer belly).

Keeping your urine warm in a natural way can be a bit tricky at first. Strap the urine pouch on yourself and walk around a bit, just to get the feel of it. You’ll be less awkward when you show up for a drug test. Just don’t be scared; these guys don’t tap you down like TSA.

For everybody asking, here is what the incognito belt looks like:

Incognito belt; you get the synthetic urine, heat pads to heat it up, temperature scale and that neat pouch so you can strap it on yourself and carry it around like your own ‘beer belly’.

Basically, it already comes prefilled with the best synthetic urine and you strap it on like a belt (girls prefer to put it just under the boobs). You can order incognito belt hassle-free here and you’ll get in about 2 days or less.

If you don’t have 2 days or would like to DIY your incognito kit, do make sure that there is a large surface area of your bag being in contact with your skin. That will help the heat transfer to keep the urine warm enough to pass a drug test.

Should You Keep Natural Or Synthetic Urine In Your Stash?

When you’re looking for clean urine, you usually ask a friend who you know is clean or just buy the synthetic urine online.

There’s always this question of which one is better – friend’s urine or synthetic urine. If you’re trying to keep them warm, there is literally no difference and you can choose either one.

The problem only occurs because your friend’s urine might be stale and smell like old urine. On the other hand, synthetic urine can be as much as $100 and you have to wait for the shipping for about 2 days. You can check the comparison of best synthetic urine kits here.

In the end, we all want to pass a drug test without having a hassle over it and I really do hope that knowing using your body heat to keep the urine at constant body temperature has helped somebody out there out of a jam.

Best Synthetic Urine 2024 Reviews: Top 9 Fake Pee Brands

synthetic-urine-vs-real-urine

I remember how crazy it sounded the first time somebody told me to use synthetic urine to pass a drug test.

It’s like, really, my best option of passing a drug test in 2024 is getting the best synthetic urine, made in a laboratory, and presenting it as my own pee?

But, asking around, one thing became crystal clear: If you want to pass a drug test, you will.

And (high-quality) synthetic urine is the answer.

The best synthetic urine kit is a fool-proof recipe to pass a drug test (if you have the balls to do it, of course).

There is the #1 best synthetic urine on this table. Can you tell which one it is? Drug testing labs sure can’t.

Which Is The Best Synthetic Urine To Use?

Ok, so let’s have a look at the best synthetic urine reviews – this is actually the most comprehensive review list I put together in hopes everybody can clearly see which fake pee is good to use and WHY it is the best.

P.S.: Interestingly, when you have the best synthetic urine in your hands, the biggest concern is not ‘Is this going to work’ but ‘How do I actually use this thing, I only have one chance at it’. That’s why with some brands, you can add a practice kit – you can test it at home (prior to the real thing) so that you can be more confident when facing the drug test:

#1 Sub-Solution Synthetic Urine (Best Synthetic Urine Kit Overall)

Sub Solution is the first synthetic urine in our review that we’ve come across that actually has urea AND uric acid labeled on the box. This is fantastic!

It took 6 fake pees to come to one that has even correct labeling on them. And it even says that – ‘(Sub Solution synthetic urine) is made from 11 different chemical compounds like urea and uric acid.’ (Source: TestNegative)

This straight-up qualifies for a top star rating – if it has urea and uric acid, it has everything!

The user reviews are brilliant as well. Here is one that sums it all up (the guy passed the urine drug test with flying colors 3 times):

Sub Solution Synthetic Urine Price And Shipping

Price is at the high end, but ‘The Sub’ is the only synthetic urine that consistently works and has a flawless track record. Here is why it is so popular and reliable:

You don’t get a premixed fake pee. You get a fully-mixed and ready-to-go synthetic urine that heats up with the use of the vial you get with the Sub-Solution full package. This is how you avoid the problem of heating fake pee up. Quite neat, right?

The Sub Solution synthetic urine shipping uses EPS for same-day shipping. What is more, shipping is free. With most synthetic urines, you have to pay $30 or so just for shipping.

All in all, Sub Solution is the best synthetic urine kit in 2024. The price is a bit higher than for other synthetic urines. I guess that even when it comes to fake pee kits, quality does come with a priceYou can check the current Sub Solution price here.

#2 Top-Rated Quick Luck Synthetic Urine For 2024

In 2024, the window of how much THC you can have in your pee sample is still wide. But it’s likely that in 2024, that window will be very narrow, and only the very best synthetic urine will be able to beat the drug test.

That’s where Quick Urine comes in very handy.

The synthetic formula of Quick Urine was designed specifically to be able to pass a drug test in 2024. That means that all the components in the premixed urine are spot on. Tested and double-tested in order to ensure that no test can tell between real urine and Quick Urine.

Here is what it looks like:

The best next-generation Quick Luck synthetic urine. A guaranteed way to beat a drug test

What is very interesting is that ClearChoice, a brand that created Quick Luck, already plans to update the formula in 2025.

Quick Luck is arguably even better than Sub-Solution. However, it lands 2nd place because it is a bit more expensive.

#3 Powdered Urine By TestClear (A Good Urine Kit)

A powdered urine kit is one of its kind. In fact, it’s not synthetic urine at all; it’s actually clean human urine. It’s been dehydrated (to prolong its use), and it can quickly be rehydrated simply by adding water. Therefore, it is one of the best synthetic urine kits to use.

Without dehydration, the urine would go stale. A good example is if you leave your own urine at room temperature for 10 minutes. It will become stale, smelly, and change color – such urine will never pass a drug test.

TestClear, the company that makes powdered urine, finds that the dehydration-rehydration process is the perfect solution for the urine not to go stale.

Here are the step-by-step instructions by TestClear that focus on how to use powdered urine:

how to use synthetic urine to pass a drug test

You can see that they, too, have figured out how to heat it – by using hand warmers. It’s not the ideal way, but you can get the real human powdered urine and the whole kit for about $60, which is a bit less than the 2 best synthetic urine kits.

#4 Quick Fix Synthetic Urine Review (Best-Known Urine Kit)

The most common and best-known synthetic urine is without a doubt Quick Fix. However, how good it actually is?

In short, I don’t know. Why? I’ve searched their website and I found no ingredients whatsoever. I don’t know what Quick Fix synthetic urine is made of.

This is what they list on their website about ingredients:

‘(Quick Fix) synthetic urine contains all of the ingredients found in natural human urine and is balanced for pH, specific gravity, and creatinine’ (source: QuickFixSythetic)

Yeah, that ‘balEnced’ is not my grammatical error, it’s theirs. I have a problem figuring out what is in the Quick Fix Plus synthetic urine though – I need specifics like urea, urobinogen…just like anything. It’s not there!

Would you buy a yogurt without a label listing the ingredients? If they can’t even put basic things like ‘this yogurt is made out of milk’ on the label, then I’m skeptical.

However, they do say something about fake pee containing everything it should contain.

But they’ve been in business since 2005, they must be doing something right. Right? Well, I don’t know – I like the facts, and the facts about what Quick Fix fake pee consists of just aren’t there. Nonetheless, it is very widely known and if you wonder where can you buy synthetic urine in stores, you can check out the Quick Fix online store here.

I can bet it doesn’t contain ‘all of the ingredients found in natural human urine’. Human urine is a complex mixture of chemicals – you can’t just duplicate it with ease. Anyways…

#5 Xstream Synthetic Urine Review (same company as Quick Fix)

Ok, check Xstream synthetic urine out – they have the same ingredient description, shipping details, and credit card data as Quick Fix. Is the same company behind them both?

They quote this the same as Quick Fix – ‘Your credit card will be billed as “513 Ventures” for your privacy.’

Am…this is the same fake sold by the same people as Quick Fix. Just the packaging and the price (here you can buy it 3oz of premixed Xstream synthetic urine for $24.95) are different.

Even the company name ‘Ventures LCC’ is the same. And yes, they operate from 2005. Just check out both websites and you’ll see it immediately.

All in all, Xstream is just Quick Fix synthetic urine. But here they sell 3oz premixed Xstream synthetic urine for $24.95 and at Quick Fix, they sell you the same stuff (in different packaging) for $39.95.

And get this: Xstream is supposed to be designed for fetish golden showers.

Here is the Xstream fake pee review in total – it’s basically the same as Quick Fix, with a lower price.

#6 Upass Synthetic Urine Review (Cheapest Fake Pee)

Upass is next on the list. By now I see that getting something as basic as a label of what synthetic urine actually consists of is hard. But then again, I’m not all that surprised that getting information on fake pee is hard (and Upass synthetic urine is no different).

However, I’ve not expected for synthetic urine producers to have so much problem with basic grammar. Check out what it says about Upass synthetic urine ingredients – ‘Carfully premixed in a laboratory with all the necessary components of human urine, including proper creatine levels, specific gravity, and ph balance making it the best fake pee around.’

That ‘Carfully’ is missing an ‘e’. But ok. Everybody can understand bad grammar (except grammar nazis, of course) but how does Upass synthetic urine measure up?

Again, they say that includes everything that human urine does – but fails to explain what are those things. Same story as with the #1 and #2 synthetic urines. Nonetheless, they do include the manufacturer’s information – that does give it a bit more credibility.

Price of Upass Synthetic Urine Kit (And Shipping Details)

One good thing about Upass fake pee is the price. For 3oz premixed synthetic pee (basically the same thing as Quick Fix and Xstream) you pay only $18.99. Quite neat, right?

However, the shipping of Upass synthetic urine kit is a bit more inconvenient. You have to order it before 3 AM PST to count as ‘bought’ on that day. Next up, you have to add (and pay for) 2-3 priority shipping. And you’ll get it in 2-3 days. It’s not an overnight thing, unfortunately.

To sum it up, this is Upass synthetic urine review:

#7 Magnum Synthetic Urine Review (these guys have the best name)

Gosh, these synthetic urine dealers do have some creative sounding names. Magnum synthetic urine is a clear example of that.

Its description at this urine sales site starts with ‘wildly popular and always realistic (Magnum synthetic urine)’. Yeah, cause this Magnum pee is so popular everybody talks about it in the cannabis community, right?

But I was pleasantly surprised that, despite lacking the basic ingredients as all best synthetic urine kits, Magnum comes with a vial of urea. That is amazing! Someone is actually putting something in these things that should be there and includes it amidst all the marketing bs!

Of course, other ingredients of Magnum fake pe are lacking – nothing new here. But I was so happy to see someone mention urea, a basic component of normal urine, in the description that I’m giving this Magnum 2 stars for ingredients.

Magnum Synthetic Urine Kit Price And Shipping Details

For Magnum synthetic urine I found prices as high as $45. The best price I’ve seen was $28 for 4oz.

I literally don’t know how much pee you need for a drug test but if 3oz is enough for other synthetic urines, I don’t think that 4oz of Magnum fake pee will give you an edge.

Shipping can be quick but if it will be quick, it will be expensive.

Magnum synthetic urine kit orders before 4 PM EST will be shipped on the same day.

Magnum is shipped via USPS and they charge $34 for overnight delivery. So that’s a bummer.

#8 Ultra Pure Synthetic Urine Review (500% guarantee?)

Also known as Ultra Klean synthetic urine. 500% guarantee struck me at first – they do give you 5 times as much as you paid for the Ultra Pure fake pe IF you failed a drug test (lost the job). That doesn’t console me one bit or makes me more confident to buy it.

In fact, it makes me less confident. If Ultra Klean synthetic urine company has to promise a 500% payback guarantee, then the product must really not be selling at normal incentives.

Before checking the fake pee ingredients, let’s check their grammar, shall we? Here is a scan from their website:

Unfortunately, Ultra Klean does not pass the grammar test (how incompetent are the people selling fake urine, I wonder). What about the ingredient list of Ultra Pure synthetic urine?

You’ve guessed it: there is none.

Ultra Pure Synthetic Urine Price And Shipping Times

Let’s fast-forward this: for 4oz of Ultra-Pure urine you’ll have to pay $32.95. A tiny bit over the average price but ok.

The shipping costs or times of Ultra Pure synthetic urine weren’t found on their website. So basically, we don’t know when it would be shipped – quite a problem there.

Overall, this is just another fake urine that is iffy at best.

#9 Agent X Synthetic Urine Review (where do they come up with these names anyway?)

A fair warning – Agent X urine is not marketed for passing a urine drug test. Rather is used for fetishes like ‘golden shower’ and for that it has 5-star reviews.

Needless to say, I don’t have experience with Agent X synthetic urine (not my thing, those fetishes). It’s sold at Dr. Greens website at a price of $29.95 for 3oz.

Comparing to the other fake pee kits, it doesn’t seem bad at all for passing a drug test. It should have all the same characteristics, but basically, we still don’t have synthetic urine that would contain a simple label of ingredients.

Final Conclusions on Using Synthetic Urine For Passing A Urine Drug Test

As we’ve seen, some people do actually use synthetic urine to pass a drug test.

How to find out which is the best synthetic urine was not an easy job – with the new updated 2024 Quick Luck synthetic urine formula coming out we see this is an evolving field. The majority of companies selling synthetic urine don’t include something as basic as the ingredients list on the packaging. This could raise eyebrows if it were mere yogurt, but when your job is on the line, I would be that much more varied.

If you want to pick the best synthetic urine, the Sub-Solution does stand out from the crowd as the best (especially with the heating chemical to bring fake pee to room temperature). You just have to choose between questionable synthetic urine for $30 + shipping or the best synthetic urine kit for $80 (shipping is free).

The choice is yours. I hope this comparison of synthetic urine kits on the market in 2024 was helpful to you or to someone close to you.
