In this guide, I’ll review the best synthetic urine products and explain how to choose them to avoid mistakes and confidently 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.

Choosing synthetic urine can be challenging due to the wide variety of products available and their differing prices.

To select the appropriate fake urine, you need to understand the specifics of the drug test you’ll be facing. It’s always better to be prepared and avoid any surprises.

What to expect during your urine drug test

Here’s the process that Concentra, Labcorp, and other drug testing companies employ.

At the outset, you’ll be asked to remove jackets, hats, and unnecessary clothing and empty your pockets. This isn’t about invasion of privacy but ensuring no cheating tools are concealed.

While collectors won’t pat you down or search you intensely, they will scrutinize items like wallets for potential test-altering substances, such as eyedrops or chapstick.

Leave these at home, as they could raise suspicion. If anything suggests you’re attempting to cheat, a more stringent observation may be required.

Lastly, you’ll wash your hands thoroughly, clearing any substances that might tamper with the sample.

Sample collection

Next, you’ll enter a specially prepared room within the bathroom to collect your sample. The collector stays outside but remains vigilant.

Experienced collectors are adept at detecting sounds that don’t match typical urination, so any anomalies might raise suspicion.

A minimum of 30 mL of urine (45 mL for a U.S. Department of Transportation collection) is required.

Remember, they’re not there to make you uncomfortable but to ensure the integrity of the test.


The setup is meticulously designed to minimize cheating risks. Sink handles are removed, and toilet tanks are sealed to deter dilution attempts.

Blue dye in the toilet bowl further thwarts water-based tampering. Personal cleaning items are also removed, and potential hiding spots are sealed.

Despite these measures, the space is kept as comfortable as possible to respect your privacy.

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 the urine will be sent to lab where it will be checked 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.

How to select the best synthetic urine


High-quality synthetic urine isn’t just about the right look or smell; it’s about the precise chemical makeup.

It must contain urea, creatinine, uric acid, and essential salts like sodium and potassium chloride.

These components ensure the urine reflects the natural properties of genuine human urine.

The look, smell, and froth

Authenticity is key. The synthetic urine should not only have a natural appearance and smell but also froth like real urine.

These sensory aspects are crucial for passing the initial visual checks.

pH and specific gravity

The pH and specific gravity are vital indicators of urine health.

A pH level between 4.6 to 8.0 and a specific gravity range of 1.005 to 1.030 are typical for human urine.

Ensuring your synthetic sample falls within these ranges is crucial for passing validity checks.

Not all synthetic urine is equal

While many products can pass basic tests, I advise against opting for cheaper brands.

These often cut corners in production, leading to lower quality that might fail under scrutiny.

Sterility is also a concern; non-sterile conditions can lead to bacterial growth, spoiling the sample.

Some manufacturers use biocide to prevent bacteria growth, making production cheaper.

However, labs are catching on to this preservative as a sign of synthetic urine.

While it keeps the urine from spoiling, it can also be a telltale sign that the sample isn’t genuine.

Premixed vs. powdered urine

powdered vs premixed synthetic urine

Synthetic urine is available in two forms: premixed in a bottle and as a powdered substance.

Powdered urine is less expensive and needs to be mixed with clean water before you enter the drug testing facility since you won’t have access to water there.

You should consider whether this is suitable for your needs.

Powdered urine is easier to store; you don’t need to freeze any remaining urine after opening it. There’s no significant difference in effectiveness between these two types of synthetic urine. Premixed urine is typically sold in a bottle with enough quantity for two uses. However, once you open the bottle, bacteria begin to grow, so you need to freeze any remaining urine if you plan to use it later.

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.

Electric urine warmer

Another great option for maintaining the temperature of synthetic urine is using an electric urine warmer.

There’s only one kit on the market that utilizes an electric heating device to keep the urine warm.

This is highly convenient since it eliminates the need to fuss with heat pads or worry about preheating the urine. You simply turn it on, press the button, and it will warm up the urine and automatically maintain its temperature.

However, it is bulky, pricey, and requires batteries.

You’ll need to weigh the pros and cons.

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

In the tense moments of a drug test, ease of use is paramount. You want a synthetic urine kit that’s hassle-free and quick to use.

Imagine fumbling with a bottle cap under the pressure of a ticking clock—it’s not ideal.

The last thing you need is an accident, like spilling the sample, which can not only be embarrassing but also ruin your chances.

Moreover, spending too much time in the bathroom can raise red flags.

Collectors are trained to notice such delays, and lingering too long might lead them to insist on direct observation. That’s a scenario best avoided.

To circumnavigate these issues, opt for kits designed with convenience in mind.

Look for features like pop-up bottle caps or tubes with clips, commonly found in urine belts.

These small details can significantly streamline the process, making it quicker and less stressful to submit your sample.

Ensuring no leaks

When it comes to synthetic urine kits, robust design is crucial.

The last thing you want is the urine bottle or bag leaking, potentially ruining your clothes and your day.

Ideally, you’d visit a store to examine and test the products yourself. However, if you’re short on time or prefer online shopping, focus on reliable brands with positive reviews and a track record of success.

The brands we recommend have been proven to be dependable and leak-proof.

Discreet packaging

Ordering online? Ensure the seller values your privacy and ships in plain packaging.

You wouldn’t want anyone, especially the delivery person, to know the contents of your package.

Reputable brands like TestNegative or TestClear are known for their discreet shipping methods, safeguarding your privacy every step of the way.

Reliable delivery

If you’re in a rush to receive synthetic urine, verify that the seller is committed to prompt delivery.

Check out reviews to see if other customers received their orders on time.

A delayed delivery could mean the difference between passing and failing your test, so choose a provider known for their reliability and speed.

Amount of urine

Finally, consider the volume of urine provided in the kit, especially if you’re preparing for multiple tests.

Standard urine tests require a minimum of 30 mL (45 mL for a DOT collection).

Ensure your chosen kit contains enough urine to meet these requirements, giving you peace of mind and the necessary quantity for successful testing.

5 Reliable synthetic urine kits for passing a drug test without getting caught

I selected these five brands of synthetic urine based on several clear criteria, so you can understand why they are the best synthetic urine kits:

Incognito Belt – best overall synthetic urine kit

incognito belt - best synthetic urine kit

As an expert in drug testing, I can tell you that Incognito Belt is one of the best synthetic urine on the market because it’s an all-in-one solution: premium-quality synthetic urine, a reliable heating method, and a convenient and stealthy way to sneak urine into a drug test.

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

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 the validity test and drug test.

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.

Choice Quick Luck: The best fake urine with heating pad

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 features a switch-flow spout which makes submission easy. You won’t need to mess with unscrewing a cap in the drug testing bathroom.

The bottle 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, allowing you to preheat it 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 it 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.

Clear Choice Sub Solution: The best budget synthetic urine kit

Sub Solution is another high-quality synthetic urine but lacks a heating option, which accounts for the reduced price.

It 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.

It comes with a patented heat activator, which means you can warm the urine to the required temperature in seconds.

It lacks heating pads. You can quickly preheat it with the heat activator powder, but you’ll need some way to keep the urine warm for the drug test.

However, keeping it in your underwear in the crotch area should be sufficient for most cases.

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.

The Urinator: the simplest way to control temperature

The Urinator is a game-changer because of its electronic heating device. You won’t have to fuss with heating pads, as this nifty tool ensures the temperature is just right.

It boasts a liquid crystal thermometer, making it a breeze to check the heat. Plus, its computerized digital controller keeps the urine’s temperature spot on. Safety is key, and all elements are sealed to prevent any mishaps.

Worried about time? It keeps the temperature steady for up to four hours. And for comfort, it includes a thermal insulating mini-blanket and an IV bag. These protect your skin and keep the heat contained.

Discretion and convenience

Discretion is paramount, and the Urinator excels here. It’s utterly unnoticeable under your clothes, hugging your waist discreetly.

Inside, you’ll find two powdered synthetic urine samples, enough for two tries. The included syringe means you can refill the bag with synthetic urine or clean urine from a trusted source. In theory, it’s reusable indefinitely.

Controlling the flow of synthetic urine is a cinch with the easy-to-use clamp. And don’t worry about size—it fits up to a 48-inch waist.



Now, let’s talk operation. It comes with a comprehensive manual, ensuring ease of use. But here’s a quick rundown:

  1. Fill the bag with 75 to 85 ml of warm water (for tests) or warm, clean urine (for actual use) using the provided syringe.
  2. Remove excess air and close the tube cap tightly. Air pockets can hinder proper heating.
  3. Connect two 9-volt batteries (preferably Duracell), wrap up with the insulating fabric, and secure it.
  4. Once the temperature reads 98 to 100 on the liquid crystal indicator, you’re set to go.


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 it smart to use someone else’s urine for a drug test?

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?

Can fake urine be detected in a drug test?

Interestingly, the answer isn’t straightforward.

While there are methods to detect synthetic urine during validity checks, such as those described by Quest Diagnostics, they don’t catch all types.

The catch is that not every client opts for validity tests due to additional costs.

Essentially, labs might detect low-quality synthetic urines that skimp on composition, but high-quality variants are much harder to identify.

Anecdotal evidence from discussions on platforms like Reddit suggests that people often pass drug tests using high-quality synthetic urine.

What type of drug test can synthetic urine pass?

It’s critical to note that synthetic urine won’t work for supervised drug tests where a collector observes the sample being given.

These are common in the military, certain athletic organizations, and some court-ordered situations.

For most standard employment and on-the-job drug tests, which are unsupervised, you’re typically alone in the bathroom.

In these scenarios, and where the test isn’t too stringent, high-quality synthetic urine can be an effective way to pass.

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

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 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.

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

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!

Then remove the paper backing of 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

Check the strip on the bottle to ensure the sample’s temperature is within the required range.

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 have the budget, the Incognito belt is unquestionably the top choice when it comes to synthetic urine kits in the USA. It boasts the most advanced formula, a dependable heating system, and a discreet way to conceal it 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.

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.
