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.

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) show exactly the same result.

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.

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 2017. Here is the list of top 7 synthetic urines currently on the market:

Here’s also a first-hand story of a guy who used it and answers pretty well if synthetic urine does work:

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.

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.

What is more, Sub-Solution retained the 2022 title as the best synthetic urine in the 2024 synthetic urine comparison as well.

Richard C., a fellow stoner, pretty much sums it up (click on the review for a bigger photo):

Sub-Solution is the new 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?

Well, it is for this guy. 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. Here is one about the Sub:

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!

‘Quick and Clean’ is how every drug test should ideally go, with or without the use of synthetic urine.

This particular brand of synthetic urine is market primarily to people who are into ‘golden showers’. Well, that is one of the ways you can use fake pee and Quick and Clean does come in quite a seductive packaging.

On top of that, Quick and Clean urine is designed especially for women. Given the lack of personal experience with golden showers, I’m not really sure if this is urine designed to be sprayed only on women or is this a woman urine (would be used predominantly on men, I suppose).

Nonetheless, the No. 1 reason why people use synthetic urine is to pass a drug test, and we are here on the mission to review all the ingredients, user-experiences and urban myths that come with every synthetic urine brand, including Quick and Clean.

So let’s jump right in.

Quick And Clean Fake Pee For Fetish

There are two kinds of fake piss packages that Quick and Clean offers:

1. Pinky synthetic pee kit (female only).
2. Normal kit with synthetic urine (unisex).

Most of the discreteness and seductiveness claims are connected with the female only synthetic urine. The Quick and Clean website even features a nice lady with a face lace, something like this:

When it comes to problems we can have on a drug test for pissing hot, the second unisex version of synthetic urine is much more useful (and gender fluid).

This is the kind of urine that people use on drug screenings; in fact, we have prepared a 2018 and 2019 best synthetic urine list in order to determine which fake pee product is the safest to use.

One thing that Quick and Clean fake piss definitely has going for it is the 2 oz container.

Would it not be better to get a 3 oz or 4 oz synthetic urine kit for the same price?

Well, normally it would but this is not potatoes that we’re buying in a store. Of course, a majority of fake piss brands out there offer a 3 oz urine + container but:

1. You don’t really need 3 oz of urine. 2 oz does suffice for a lab test.
2. It’s easier to hide a 2 oz flash under your armpit than a 3 oz bottle.

These two reasons made Quick and Clean urine quite useful and easier to use/hide when you drug test appointment is up.

Ingredients

The essential part of answering the question “will this synthetic work on a lab drug test” is hidden in the composition of synthetic urine. In short, what is the bright yellow solution you can substitute for real urine actually made out of?

Quick and Clean is rather shy to reveal what exactly is inside their mixture (shockingly, only a few fake urine brands disclose this information).

Without knowing if there is urea or uric acid in Quick and Clean piss, we can’t really know if it will work on a drug test or not, right?

Wait Until 2019 For Synthetic Urine Reviews

Usually, we can find a lot of reviews of brands like Sub-Solution, Quick Fix and so on on a number of different forums by people who have actually used and passed or failed a drug test.

However, Quick and Clean is quite a novelty products (I think it was launched in 2016) and it is one of the least known synthetic pee brands around.

That means that there is a lack of Quick & Clean urine reviews. The following question about it is the only reference we could find of Quick and Clean (it has posted as a synthetic urine related question on Grasscity forum):

The guy buying synthetic urine really points out the relevant questions about the Quick & Clean urine: it’s 15$ cheaper than Quick Fix but it does not say ‘contains urea’. In most of the cases in which synthetic urine is detected on a lab test, the urea was missing in the fake pee.

Does Quick and Clean includes urea? We simply don’t know and that is a problem.

For some real information, we’ll have to wait on some of the 2019 synthetic reviews to tell us if it works or not.

Our Verdict

New and fetish-focused brand of synthetic urine. How does it hold up on a drug test? Well, we don’t really know because the information about the ingredients is not disclosed and there are no relevant reviews of the Quick and Clean brand out there as of yet.

Some red flags do include using hand warmers (this again) to warm it up; that’s just nasty and risky business.

We get it.

You have a drug test in your imminent future. You also pretty much know you’ll piss hot unless…

…unless you get creative.

We’ve all been there. The first of drinking boatloads of water to pass a drug test helps just a little and you’re sure that just a little help won’t cut it.

People who are pissing hot are passing lab tests every day; with the right choice of synthetic urine, of course.

The thing about synthetic urine is that you want to pick one that works for sure and that:

• Easy to heat up.
• Works for all urine drug tests.
• Most important: undetectable by lab-issued drug tests.

Labs are getting more and more creative at detecting synthetic urine. That’s the real reason why the best synthetic urine is the latest or the most updated formula.

A kind of formula that lab-issued drug tests can’t detect. And the story of Quick Luck synthetic urine in 2024 is a story about how not to be only one but two steps ahead of the lab techs.

That’s the only way to guarantee you’ll pass a drug test on short notice.

Quick Luck – Synthetic Urine For 2024

It is essential for a synthetic urine to keep up with the drug screening standards.

For example, a few years ago labs started testing for urea. Why?

Well, every real urine contains urea (it’s a small chemical in urine). Most of the synthetic urine kits didn’t have urea. That’s why when the drug screening test determined that a urine specimen doesn’t include urea; it has to be synthetic urine.

From then on, every high-quality synthetic urine (at least all of those that don’t cost less than $50) does contain urea.

In 2019, the window of how much urea 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 how it looks like:

What is very interesting is that ClearChoice, a brand that created Quick Luck, already plans to update the formula in 2024.

They know they have the best synthetic urine of 2024 on the market, but the expiry rate of Quick Luck urine is September 2024. After that chances are they will already update the formula again in order to be the top of the top brand out there.

Temperature, Temperature, Temperature

The all-inclusive and thorough formula of synthetic urine might not be enough.

One important factor that differentiates good synthetic urine from bad synthetic urine is how well can you adjust its temperature.

Even with Quick Luck synthetic urine, you have to ask two things:

1. How will I heat it up to body temperature (90-100F)?
2. How will I maintain that temperature before the testing?

Up till now, there were synthetic urine kits that did either one or the other. Quick Luck is the first synthetic urine on the world that does both!

It includes the patented heat activating powder; this stuff raises the temperature of Quick Luck urine to body temperature in seconds.

Secondly, you get heat pads with every purchase. Those help you to keep the synthetic urine heated for 1-4 hours, giving you more than enough time to go through the all ordeal of doing the urine drug testing.

Verdict – Best Synthetic Urine

All in all, Quick Urine represents the next generation of synthetic pee that is:

1. Very accurate.
2. Easy to use temperature-wise.
3. Undetectable.

Having all these three properties covered, Quick Urine is one of a kind synthetic urine for 2024. Be sure to order the latest batch (ClearChoice is committed to updating the formula in order to remain two steps ahead of the lab detections):
