We Reviewed The Top Fake Pee Options For Passing A Drug Test In 2023 – Here Are Our Top Picks

In this guide, you will learn everything you need about synthetic urine and how to use it to pass a drug test.

If you’ve taken any detectable drug or smoked cannabis in the past few days, you will fail a urine drug test.

Moreover, regular marijuana users can test positive after months of abstinence because THC is stored in body fat cells and is continuously released into the blood.

But don’t worry. Whatever the reason for the drug test, you can pass it with high-quality synthetic urine if you know which brand to buy, how to prepare it, and the pitfalls to avoid.

4 Most Reliable Synthetic Urine Kits For Passing a Drug Test Without Getting Caught

I’ve chosen these four brands of fake urine using several clear criteria, so you can understand why they are the best fake urine kits:

Any of these will do if you need to pass a basic pre-employment unsupervised drug test.

However, if you know you’ll be supervised, choose the option with a stealth belt or prosthetic.

Clear Choice Sub Solution – Best Synthetic Urine Kit

sub solution synthetic urine kit back and front

As an expert in drug testing, I can tell you that this is one of the best synthetic urine on the market. Here’s why:

Firstly, Sub Solution Synthetic Urine looks, smells, and foams like real human urine. This means it will pass the initial visual check by the lab collector.

But that’s not all – it will also pass all validity checks, meaning the lab won’t be able to tell that it’s synthetic.

What’s more, Sub Solution Synthetic Urine doesn’t contain biocide, which is a dead giveaway that it’s not real urine. So, the labs won’t be able to tell that this urine is synthetic.

It comes with a patented heat activator, which means you can warm the urine to the required temperature in seconds. However it’s important to note that using this stuff has a few downsides.

drawback First off, you need to deal with the vial containing the powder. During a drug test, they’re going to ask you to empty your pockets. If they see the vial, they will likely make you submit the sample under direct observation. This means you’ll not only have to find a way to hide the urine bottle, but also this vial of heat activator powder. It’s an extra problem to deal with, and not an easy one.

Additionally, finding a safe place to leave the vial before going into the drug test can also be a real headache.

drawback Another drawback of heat activator powder is it’s really only useful for heating the sample. It doesn’t maintain the temperature. After you’ve heated up the urine, it begins to cool down again. To prevent this, you need to keep the urine bottle close to your body, which can be quite inconvenient.

Let’s say you have a long wait before your drug test, that cooling process could drop the temperature of your urine below the acceptable level. That’s a risk you might not want to take.

That’s why I tend to favor heating pads. They might take a bit longer to get the urine to the right temperature, but once they do, they can keep it there for up to six hours. It’s a solution that just provides a bit more peace of mind.

The small bottle is designed to be easily concealed between your legs or in your scrotch or bra, allowing you to discreetly bring it into a drug testing facility.

To make things even easier, a temperature strip is attached to the bottle so you can easily check if the temperature of the urine is as required.

The urine bottle has a switch flow spout, so you don’t have to unscrew the cap to submit the sample. And, the bottle is leakproof, so you don’t have to worry about any embarrassing spills in your pocket.

This fake pee comes in a small, powdered form that’s easy to store. And, there’s enough urine for two uses, so you can pass two drug tests.

It’s also unisex, so both males and females can use it.

However, the downside is that you need clean water and about five minutes to prepare the urine.

Overall, if you need to pass a drug test and want to be sure you’ll pass, Sub Solution Synthetic Urine is the way to go. It’s easy to use, undetectable, and reliable.

This kit costs $90, and I recommend adding a stash leg belt to the kit so that you can discreetly attach the bottle to your leg.





Remove the screw cap from the plastic collection container and fill it with lukewarm tap water to just under the cap.

The tap water should not be too hot or too cold.

Add the entire contents of the synthetic urine vial to water in a mixing container, screw the cap on the bottle and gently shake the container until the powder has completely dissolved.

The synthetic urine can be mixed with water up to eight hours before use.

Attach the sample tightly to your underwear. I recommend using a stash leg belt.

Put on the baggy bottom and go to the testing location.

Before you go in, you need to heat the sample to 90°F-100°F temperature.

Tap in about one-third of the heat activator powder (shake it to ensure it’s not clumped), and gently shake the sample until it dissolves.

Watch the temperature strip, and add a little more necessary. You want to get a reading as close to 100°F as possible without going above that.

That’s it. Sub Solution gives you complete, granular control over the sample temperature. It’s complex, and it’s easy to manage.

Clear Choice Quick Luck Premium – Best Option for Short Notice Drug Tests

quick luck synthetic urine kit front and back

Unlike Sub Solution Synthetic Urine, Quick Luck is already premixed, so there’s no need to wait around to mix it.

This feature makes it perfect for those who need a quick solution without any hassle. The product is a little bit more expensive, but many describe it as Sub Solution on steroids.

The most superior formula on the market, Quick Luck will pass the visual inspection test, validity test, and drug tests, making it completely undetectable by the labs.

Plus, the urine bottle has a switch flow spout and is leakproof, so there’s no need to worry about any spills.

The small bottle is also easy to hide on your person between your legs, in your scrotch, or in your bra, making it easy to sneak into a drug testing facility.

Quick Luck comes with heating powder that will warm the urine within seconds, as well as two heat pads that can keep the urine warm for up to ten hours.

However, when they say these heating pads can maintain temperature for 10 hours, it kind of sounds like a marketing gimmick to me. I think it’s more realistic, and a safer bet, to count on them for about 6 hours.

A temperature strip is attached to the bottle, so you can check if the temperature is within the normal range.

And, the product is unisex, with detailed instructions that make the belt easy to use.

Another benefit of Quick Luck is that it has a shelf life of up to two years and can be frozen and reheated, making it a great option for future drug tests.





The sample is premixed and ready to use. There’s no need to mix it with water.

Outside the testing facility, use the heat activator powder to bring the sample to within the correct temperature range (between 90°F and 100°F).

Place the sample into your underwear that will keep it warm and discreet, ensure you wear baggy pants, and then go in and submit your sample.

Incognito Belt – An Easy Way to Sneak Urine into Your Drug Test

incognito belt synthetic urine kit

If you need a convenient way to sneak urine into a drug test, the Incognito Belt may be the solution you’re looking for.

Here’s why:

Priced at $130, the Incognito Belt comes with both the urine and the device.

It’s discreet – no one will notice that it’s hidden on your waist.

incognito belt on a waist male vs discreet

The belt has a drain tube and releasing clip, making it easy to use and submit the sample discreetly.

It has a Velcro adjustable belt that can fit up to a 48″ waist.

The urine is already premixed, so there’s no need to mess with mixing powder with filtered water.

The urine looks, smells, and foams like real human urine, making it easy to pass the initial visual check by the lab collector. And the urine formula is considered the best on the market and will pass all validity checks.

Plus, it doesn’t contain biocide, so the labs cannot tell that it is synthetic.

The Incognito Belt includes a temperature strip attached to the bladder bag, making it easy to check if the temperature is as required.

The urine bag will be close to the body, helping to keep the urine temperature normal. It comes with two heating pads, making it even easier to warm the urine.

There’s enough urine for two uses, so you can pass two drug tests with it.

The product can be used by both males and females, and detailed instructions make the belt easy to use.

It also has a shelf life of up to two years, so you can store it for future drug tests.

Overall, if you need a convenient and discreet way to sneak urine into a drug test, the Incognito Belt is definitely worth considering.





Open up the heat pad and remove the adhesive backing.

Give the heat pad a couple of good shakes to activate it.

Stick the heat pad to the bladder bag, between the belt and urine pouch.

Wrap the Incognito Belt around your waist (under ALL your clothing) with the temperature strip touching your skin and the drain tube pointing to the floor.

Close the white clips and cut the end of the tube off.

When you need to submit the sample – unfasten the white clips to drain the contents.

TestClear Powdered Urine Kit

TestClear Powdered Urine Kit

The listing on the TestClear website now describes it as a “human urine simulation” product.

I think the wording was originally confusing, and people read it as meaning it was human urine that was freeze-dried into a powder. It’s not. It’s another synthetic urine.

TestClear powdered synthetic urine kit is complex in its composition.

It contains everything you need, including urea, uric acid, and creatinine. It’s everything you would expect from the TestClear brand, which is highly trusted.

The complexity of the formula is not as good as in Sub Solution, but this is a good product for an affordable price of $50.

The kit comes with two heat pads and a temperature strip.




Pour the powdered urine in the small vial into the larger 50 ml tube.

Slowly fill the tube with water to the very top, screw the blue cap on tightly and shake until the powder is completely dissolved.

Apply the temperature strip on the front of the 50ml tube. Open the heater package, peel the paper off of one heater and stick it to the backside of the tube, directly opposite the temperature strip.

Before submitting your sample verify the temperature is within the correct range (90°F – 100°F).

Is Using Someone Else’s Urine For A Drug Test A Smart Idea?

In theory, you can use someone else clean urine to pass the drug test. Despite that there are methods to keep urine fresh for a drug test, I don’t recommend it. The chance of failing is exceptionally high because of the following reasons:

  1. You never know if the urine is really clean.
  2. Human urine spoils fast, so you cannot guarantee it will stay good until the submission.
  3. You still need to heat it to the right temperature and buy a heating pad. You can save money and use a bottle of warm water to heat your sample, but the results are not guaranteed.

Do you really want to risk that much?

What to Expect During Your Urine Drug Test

The drug testing procedure is quite straightforward.

Most of the drug tests are unsupervised. You will be behind the screen or in another room.

If the drug test is supervised, the collector will be in the room with you. However, he will not directly look at you when you submit the sample.

In this case, you’ll need a urine bag with a tube or a prosthetic attachment to discreetly submit your urine.

If the drug test is observed, someone will look straight at you as you pee. Such tests are rare and are done for law enforcement purposes.

Getting The Results

After that, your sample will go through four levels of analysis:

The collector will check the temperature and the signs of fake urine.

So if the color is not natural, or urine clogs or does not froth like normal urine, it can cause suspicion.

Then they will check your urine with the dipstick for creatinine levels, pH, and specific gravity for signs that the urine is fake or adulterated.

Next, your urine will go through the basic immunoassay analysis. This analysis is done with the panel drug test, and it will detect if there are drug metabolites in your urine.

The next step is the advanced gas chromatography test. However, this test is expensive and time-consuming and is done in very rare cases.

Overall, you’ll most likely face an unsupervised drug test that has basic validity checks and a standard immunoassay analysis completed during it.

This is the easiest combo to pass.

The Top 8 Considerations Before Purchasing Synthetic Urine

Biocide Problem

Several years ago, fake urines started to fail the drug test. That was because the labs began to look for the Biocide in the samples.

Biocide is a preservative that is used to keep urine from spoiling. Unfortunately, it is also a footprint by which labs can identify you are using fake pee.

So you should look for brands that don’t use Biocide in their formula.

Formula Complexity

The natural urine formula is very complex. The synthetic urine formula must be as close to the real urine as possible.

Generally, synthetic urine contains urea, creatinine, uric acid, sodium chloride, and potassium chloride. So the brand you choose must have at least these components.

It also must have pH and specific gravity within the normal range:

Urine Appearance

Fake pee must look, smell, and froth like natural urine. If the color or smell is strange, your sample can cause suspicion during the visual inspection.

Heating Method

After visual inspection drug test collector will check the temperature of your sample. The temperature of human urine is 97°F – 100°F.

But because the sample cools down, it can have a temperature of 90°F – 100°F. So if the temperature is out of that range, the sample will be rejected.

This step is critical and the main reason people fail to pass the drug test with fake urine!

So the urine kit must contain a reliable and convenient way to warm the urine to the required temperature.

You can heat the urine with the heat pad or heat activator powder.

handwarmers heat pad versus heat activator powder

The heating pad is a pad with a chemical element inside. When you activate it, it heats the bottle with the urine to the body temperature within 1 hour. Then it keeps the temperature for up to 10 hours.

Heat activation powder heats the urine to the desired temperature within seconds. But you need a place to hide the bottle with powder before entering drug testing service. So using heating pads is more reliable and convenient.

Temperature Strip

You’ll want to understand if the temperature of your sample is within the required range. So you need a temperature strip to check it.

Best synthetic urine kits have such strips attached to the bottle, making it convenient to read.

Ease of Use

You cannot walk into the drug testing facility with a bottle of urine in your hands. So you need a way to hide it on your body.

Best kits come with a stealth belt or stash leg strap that allows you to hide the bottle on your body discreetly.

Powder vs. Premixed

powdered vs premixed synthetic urine

Fake urine can be sold in the form of powder or can be premixed in a bottle. Powdered urine costs less but requires time and clean water for preparation.

This can be inconvenient if you have to pass a drug test on short notice.

Success Rate and Reviews

That’s obvious, but the urine brand must have a high success rate and reviews. You don’t want to risk your dream job, right?

What Type of Drug Test Can You Pass With Synthetic Urine?

Most of the urine brands will pass the basic dipstick validity check. Best brands will allow you to pass the immunoassay level analysis as well.

The immunoassay test is used in pre-employment drug testing and most other situations.

Only the highest quality urine will pass a gas chromatography drug test, but such tests are very rarely used because it’s costly and time-consuming.

Synthetic Urine Brands to Avoid at All Costs

These are popular but low-quality brands of fake urine that you should avoid for a variety of reasons:

None of them are complex in the formula. In the worst-case scenario of Magnum synthetic urine, it actually contains a separate vial of uric acid that they started putting in with the synthetic urine because it didn’t contain any!

Step-by-Step Guide to Using Synthetic Urine: Don’t Get Caught

Prepare Your Sample

If you use premixed urine, you don’t need to prepare it.

If you have urine powder, do the following:

Remove the screw cap from the plastic container and fill it with lukewarm tap water to just under the cap.

The tap water should not be too hot or too cold.

Air can spoil synthetic urine, so do not open the synthetic urine vial until ready for use. Likewise, do not open the heat activator vial until ready for use.

Add the entire contents of the synthetic urine vial to water in a mixing container, screw the cap on the bottle and gently shake the container until the powder has completely dissolved.

Apply Heat Source

If you will use heat activation powder, skip this step.

If you use the heat pad, microwave the sample for about 10 seconds on full power. Then, shake it gently, and watch the temperature strip.

If there is no reading, do it again for another 10 seconds. You want a reading on the temperature strip that is as close to 100°F as possible.

Remove the paper backing on the heat pad and stick it to the bottle.

heating pad attached to the bottle

The heat pad will provide up to 10 hours of heat once activated.

You can skip the microwave part, but then you’ll need about an hour to warm the sample to the required temperature.

Note: Once activated, the heat pad will barely feel warm to the touch, and this is perfectly normal as the heat pad, as the heat pad, combined with your body heat, will raise the urine to its ideal temperature within 1 hour.

Hide The Sample On The Body

There are three convenient options to hide synthetic urine on your body.

You can use the stash leg belt, stash boxers, or waist belt.

Boxers and waist belts cost more than leg belts, but actually, there’s no reason to pay more.

The only reason to use a waist belt is in case your drug test is supervised.

Also, you can save money and sew a pocket on your underwear.

Put the bottle with the sample into a discreet place on your body and go to the testing facility.

Before Entering The Facility

If you use a heating pad – check the strip on the bottle to ensure the sample’s temperature is within the required range.

temperature strip on urine bottle

If you use the heat activator powder, do the following:

You need to pour the powder into your sample to raise its temperature.

For easy pouring, verify that the heat activator content is in a “loose” or “free-flowing” granular form.

If the granules are solid or partially solid, tap the vial against a hard surface. This will break down any clumps and bring the heat activator back to its original granular form.

If you do not see any temperature indication on the strip, this means your synthetic urine temperature is below 88°F.

In this case, carefully add 1/3 of the heat activator into the mixing container.

If the temperature on the strip indicates 88°F to 92°F, add only 1/4 of the heat activator into the mixing container.

Caution: adding an excessive amount of heat activator may overheat the solution; very rarely, one will need to use more than 1/2 of the heat activator without overheating the solution!

Now you are ready to submit your sample!


Synthetic urine is used to calibrate drug testing equipment. Also, doctors and scientists use the best brands to simulate real urine. This is tried and trusted and will pass a drug test unless suspicion is aroused.

If you’ve got the money, the best synthetic urine kit is undoubtedly Quick Luck. The most complex formula, premixed, and it has 2 heating options for your convenience.

But if you don’t want to spend quite as much, and have preparation time, then Sub Solution is an equally good option, but you’ll need time to prepare the urine and some place to hide the heat activator powder.

If you must pass a supervised test, use the Premixed Synthetic Urine on an Incognito Belt. It costs more but allows you to submit a sample even while being watched.

At the budget end, TestClear Powdered Urine Kit is the best option. It is simple in formula but capable of passing a drug test as long as the sample isn’t scrutinized in more detail.


How to store and transport synthetic urine?

Most synthetic urine kits have a shell life of two years. You should store it in a cool, dry place and avoid direct sunlight. Keep it away from any sources of heat or moisture. When transporting synthetic urine, keep it in an airtight container.

Can you freeze synthetic urine?

Synthetic urine is not a real urine sample and, therefore, cannot be frozen.

It is made up of a combination of chemicals and other substances that are designed to mimic the properties of real urine.

Freezing synthetic urine would alter its composition and make it unusable for testing purposes.

Can the test detect synthetic urine?

Best synthetic urine brands will pass all lab tests, including immunoassay analysis and gas chromatography.

However, some cheap brands don’t have complex formulas or visual appearances like real urine. As a result, such brands can only pass the dipstick test for creatinine levels, ph, and specific gravity.

Is synthetic pee unisex?

Yes, synthetic urine can be used by both males and females.
