Using synthetic urine to pass a drug test is growing in popularity. Indeed, former world heavyweight boxing champion, Mike Tyson, admitted using it to pass drug tests at the peak of his career.

Drug tests can detect THC-COOH metabolites in the system for up to 8 days in first-time users. For regular users, the timescale potentially increases to several weeks.

Synthetic urine is an option for passing a drug screening, but drug testing companies are using more sophisticated methods to uncover such deception. Modern labs are capable of determining whether urine comes from the human body.

As a result, a synthetic urine kit must be highly advanced to prove successful. This article outlines everything you need to know about synthetic urine. This includes choosing the best brands, spotting bad products, and information on how labs can distinguish between synthetic and real urine.

What Is Synthetic Urine?

Also known as ‘fake pee’ or ‘laboratory urine,’ synthetic urine is a substance created to mimic the appearance, chemical properties, and, most importantly, the composition of human urine. All of the major components of natural urine are found in high-quality synthetic urine, including (among other things) creatinine, uric acid, urea, ammonia, and sulfates. The pH level and specific gravity in “real” and synthetic urines are nearly identical.

Fake pee is available in a few common forms, such as dried powders and pre-mixed solutions, and both of these forms expire with time.

The Anatomy of Synthetic Urine

Synthetic urine is a liquid scientifically mixed to form a urine-like sample. Here are four main components creators must consider:

Color: Chemists have figured out how to make synthetic urine look real. It is typically a ‘warm’ yellowish color rather than being colorless.

Creatinine level – Chemists include creatinine in fake urine to make it seem like it came straight out of the body. All effective synthetic urine products must contain some creatinine. Testers look for it because it is a by-product of muscle metabolism.

Temperature – Chemists first check the temperature of actual urine and add chemicals for the liquid to appear authentic.

pH Level – Measured from original urine, certain components are diluted to make it appear original. Then the urine is tested and improved if necessary.

There’s no doubt that synthetic urine is the fastest and most effective way to pass a urine test. However, using a kit requires skill and a bit of luck. After all, you have to smuggle it into the test and make the swap without the test inspector seeing you.

How to Select the Best Synthetic Urine to Pass a Drug Test

Many artificial urines are unreliable. Some are detected in drug tests, while others don’t work. You must choose the right brand and a product that you know is legit.

There are countless synthetic urine kits on the market, making it tough to choose the ‘right’ one. Here are a few things to consider to help you narrow your search:

Uric Acid: Since normal urine contains uric acid, most labs will test for its presence when conducting a drug test. Check the product label to ensure it has this vital ingredient.

Brand Reputation: The increased demand for synthetic urine has caused a significant increase in counterfeit products. Don’t be afraid to spend a few extra dollars to get the best brands, and check out WayofLeaf reviews on well-known synthetic urine brands. Also, research customer feedback to see if the product was successful for others.

Temperature: The best products have a heating pad to keep the urine warm and a special strip that displays the current temperature.

Shelf Life: Drug tests usually pop up unexpectedly. When it is testing time, the last thing you want is to discover that your synthetic urine kit’s expiry date has passed. Make sure you choose a product with a long shelf life; the best brands ensure their synthetic urine lasts 2-3 years when stored properly.

Signs of a Bad Synthetic Urine Kit

As we’ll outline next, the stakes are high when choosing synthetic urine kits. It is essential to stick with highly regarded brands such as Quick Fix . Its products contain all the necessary ingredients to potentially help someone pass a drug test. The company also ensures its products don’t contain metabolites that could interfere with calibration equipment used for a urinalysis.

Unfortunately, there are at least half a dozen bad or unreliable synthetic urine kits for every Quick Fix standard product. Premium-grade kits can mimic the musty odor of urine and ensure the liquid is slightly foamy on top. In contrast, low-grade kits produce a liquid that doesn’t look or smell like the real thing.


In general, if you detect an excessively strong odor, it is a sign that the kit is bad. This also happens with high-quality products once they expire. Oxygen exposure can oxidize the urine and ruin it.

Another worrying sign is if the sample becomes cloudy. Once fungi and bacteria breed in the fake urine, they compromise its appearance. Also, be sure to throw the product away if the urine is congealed.

What Happens If I Get Caught?

The most obvious punishment is the loss of employment. Even though cheating a drug test isn’t illegal by federal law, at least 18 states have specific laws against it. In South Carolina, using synthetic urine or any other means to cheat a drug test is an offense that could see you spend three years behind bars.

In North Carolina, helping someone cheat a drug test for a second time is a Class I felony. Oregon law states that cheating a drug test is a Class B misdemeanor, leading to a potential prison term of six months. Here are a few other states that punish the use of synthetic urine:

  • Texas
  • Oklahoma
  • North Dakota
  • Virginia
  • Arkansas
  • Nebraska
  • New Jersey
  • Illinois
  • Pennsylvania
  • Wyoming

Therefore, before you buy synthetic urine, check your state’s laws to determine the punishment if you’re caught. From there, you have to decide whether the risk is worth it. Bear in mind that sellers of synthetic urine accept no liability if you’re caught or the test fails. These companies may not mention that their product is designed to help you pass a drug test.

How to Use Synthetic Urine

While fake pee for drug test kits may have different processes, they generally work on the same principle. Many synthetic urine kits come with heating pads to test the temperature and belts for easy hiding around the waist.

Shake the heating pad a few times and attach it to the belt’s bag on the day of use. Next, close the clips and cut the tube to the length needed, then wrap the belt around your waist and ensure all your clothes cover it. The temperature strip must be touching your skin, and you should point the tube towards the ground. You must attach it at least an hour before the test.

The last step is the trickiest and the most critical. Once you have the pee cup, you can unfasten the clips and pour the synthetic urine into the required container or cup. This step is dependent on you not having a ‘supervisor’ watching over your shoulder. If you do, the process becomes significantly more challenging.

Do I Have Any Other Options?

Now that you know the difficulties involved and possible penalties if caught, you would be forgiven for having second thoughts. A detox product is a viable alternative if you have an impending drug screening and are worried about failing.

Detox products are designed to help you remove THC-COOH metabolites from the body rapidly. For example, Toxin Rid’s products contain iron, sodium, magnesium, chloride, and other ingredients. The brand offers programs ranging from 3 to 10 days to help you detox. Of course, it doesn’t specifically mention that the product is for passing a drug test!

Detox products are less effective than synthetic urine. However, if you fail your test, you will probably lose your job but don’t have to worry about facing criminal charges!

Powdered vs. Liquid Synthetic Urine

Synthetic urine is available in both powder and liquid form, and many people wonder which is the better of the two.

We have explained the liquid form of synthetic urine, but what is powdered urine?

It smells, looks, and behaves chemically like drug-free human urine. Rather than receiving an already diluted form of synthetic urine, you buy the powder and mix it with water before the drug screening. It is 100% natural human urine that has gone through mass dehydration, making it one of the easiest and most accurate ways to pass any drug test.

Powdered urine is 100% natural human urine that has gone through mass dehydration.

Dehydrated urine is drug-free, giving you a higher chance of passing the test. The urine retains its properties and is identical to real urine, producing accurate results in a calibrating machine. Each kit should come with an instruction manual to help you correctly mix the powdered urine with water.

However, a recent synthetic urine review found that the liquid form is superior to its powdered counterpart because it is already mixed and ready to go. Meanwhile, powdered urine requires you to do it yourself, which increases the risk of error.

Can Labs Tell the Difference Between Real and Synthetic Urine?

Yes! Laboratories can determine whether someone cheats during a urine drug test. Regardless of how good a fake urine product is, there are biological markers in human urine that a synthetic version can’t replicate. However, typical drug screens don’t include testing for these markers.

It is also a fact that drug testing labs are a ‘for-profit’ industry. They are likely only to perform the minimum requirement as additional testing eats into their profit margins. Labs tend to look at the following:

  • Gravity Levels: Should be between 0.1002 and 0.1003
  • pH: Urine can be between 4.5 and 8.0, although individuals with health issues such as kidney stones could have urine falling outside this range
  • Temperature: Between 94- and 100-degrees Fahrenheit
  • Creatinine: Between 601mg and 2936mg
  • Urea: Between 12 and 20 grams
  • Froth: Minimal froth is best; low-grade kits have adulterants and produce excessive froth

Therefore, high-quality synthetic urine should pass a test over 99% of the time. Indeed, this is what some sellers claim. As long as a fake sample has the right temperature, creatinine levels, pH, and density, it should pass a test.

Other Reasons to Use Synthetic Urine

Apart from using synthetic urine to pass a drug screening, it has the following uses:


Animal Repellent: Garden enthusiasts use animal repellent to keep rodents from their favorite plants. Synthetic urine works just as well as the real thing and brings down the overall costs for gardeners.

Pranks: This is the most entertaining reason to use synthetic urine for people with a little extra time on their hands!

Education: Medical students train using synthetic urine. Typical training includes urinalysis tests and clinical experiments.

Cleaning Agent Tests: Fake urine is very popular among salespeople and marketers. They use it to demonstrate the effectiveness of various cleaning agents, especially for carpets and furniture that need urine stain cleaners and odor removers.

Science: Scientists use synthetic urine for various purposes, from preparing for Mars missions to developing new urine tests for different diseases.

Final Thoughts on Synthetic Urine

Mandated testing is commonplace in the workplace, particularly in the United States. While there are other suggestions for passing drug tests, such as detoxing and consuming large amounts of water, synthetic urine is certainly the most reliable and effective.

Although it could help you pass a drug test, there are no guarantees. Also, we must point out the dangers. Being caught using synthetic urine will almost certainly lead to contract termination and even legal action in some states. Therefore, you use synthetic urine at your own risk.

If you are looking for a detox product, we’ve tested quite a few. Below are the results from the products we tried out to date.


How Long Does Synthetic Urine Last?

A lot depends on how you store it. Properly stored synthetic urine can last for up to 3 years. However, factors such as oxygen exposure, high humidity, or a dirty storage environment will cause the product to become unreliable after a relatively short period.

Where Can I Buy Synthetic Urine?

While third-party sites sell such products, your best bet is to go directly to a seller’s official website. Make sure you check out the brand’s reputation before making a purchase. Quick Fix, UPass, and Clear Choice are regarded as high-quality synthetic urine sellers.

What is Synthetic Urine Made Of?

It depends on the brand but usually consists of urea, water, creatinine, uric acid, and pH balance.

What Happens If You Get Caught Using Synthetic Urine?

That depends on where you live. The legality of synthetic urine varies from one state to the next, and at least 18 states have outlawed the manufacture, delivery, sale, or use of the product. Therefore, you could go to prison if caught using fake pee! Certainly, you can expect termination of your contract at the bare minimum.

Does Synthetic Urine Expire?

Yes. It can last 2-3 years as long as you store it correctly. After this time, the quality begins to deteriorate, and it is much easier for a lab to spot fake urine. If you buy a synthetic urine product, don’t open it unless necessary. Use an adulteration test strip before using it to ensure it is still good, and don’t reheat and cool it several times over.

Is Synthetic Urine Legal?

Federal law doesn’t make it illegal to cheat on a drug test. However, many states make the process illegal, with punishments ranging from fines to imprisonment. For example, in South Carolina, users and sellers of products designed to cheat drug or alcohol tests can receive a prison sentence of up to three years.
