“I’ve seen this stuff promoted here a lot as an easy way to pass a drug test. So I’d like to let everyone know that it does not fail-proof. I took a test on Friday and just got a call from the clinic today that there were issues with the sample, and I’ll need to retake the test. I got the stuff from their direct website, checked the batch number, and the temp was perfectly in range, so I don’t know what the issue is. Think I’m going to go with actual urine this time. Be careful, everyone, because this stuff isn’t perfect.”
R/Tress- Reddit User


“I’ve used Quick Fix several times now for pre-employment drug tests with no issues whatsoever. I would recommend this product.”
Sarah, Chicago

Reviews By Consumers:

“My only gripe against this product is the warmer it provided. Long story short, it was too hot, and my urine sample was not accepted. I’m in the bathroom blowing on a hot sample and was just told to come out if I can’t pee. For anyone using this, either don’t attach the heater to the bottle or use hand warmers over toe warmers. Say what you want, but I don’t feel you should worry about overheating once it’s concealed.”
Larry, Clinton Township


“I got the basic powdered urine kit and used it exactly as directed. It’s more expensive than some others, but it’s not synthetic. It’s real powdered urine. Got the negative result for the 10-panel, pre-employment drug screen.”

Buyer’s Guide: How To Choose The Best Synthetic Urine?

There are a few things you need to look out for when you purchase fake urine for drug testing:

  • Low cost: Fake urine isn’t cheap. It must contain numerous factors, including creatinine and urea. All of those components are not inexpensive. So, if a synthetic urine brand offers you a deal for $20, then you are buying low-quality synthetic urine unlikely to pass a drug test.
  • Packaging and marketing: You can usually tell whether a company is serious about its product by looking at the fake pee packaging and marketing. A lab-tested good will always appear to be a trustworthy and effective piece of equipment. It will most certainly not have the title ‘UStream’ on it.
  • Non-credible third-party website: If you are buying something from a third-party website like Amazon or eBay, it is possible that you are being scammed. The deals might be great, but make sure that you don’t skimp on quality and get a product that will help you pass any drug test.

What is Synthetic Urine?

Synthetic urine is a liquid that will help you to pass a urine drug test. The chemical makeup of this synthetic urine is designed to match that of human urine as closely as possible. There are many different fake pee brands, but they all have the same goal: to help you beat a drug test.

How Does Synthetic Urine Work?

Synthetic urine works by providing a fake urine kit or fake urine sample containing all of the same chemicals found in human urine. The main difference is that synthetic urine does not contain any of the banned substances that may be detected in a drug test.

The process of using synthetic pee is very similar to the process of using normal urine. The only difference is that you put the synthetic pee into the cup instead of your own urine. If you have the right equipment, you can even pretend to pee into the cup by making movements that look like you are urinating.

However, you will need to be careful about the temperature of the synthetic urine. Most people tend to go wrong with synthetic pee when they use expired products, don’t maintain the temperature, or store the created artificial urine for longer than six hours. Most urine kits have a temperature strip to help.

Resource #1: Here’s a Chart Representing Drug Detection Times

Chart: How long do drugs stay in your system

Every substance that enters your body must go through the natural process of metabolism. Whether it’s alcohol, cannabis, or any other type of drug, it leaves traces in your urine and blood. Once a substance is ingested, it will have a detection period where it will show up in a drug screen or a urine drug test. It means you will end up not passing a drug test with your real urine.

Certain factors can influence the time frame such as age, body fat, the frequency of use, and physical condition. Underestimating how long the drug stays in your system, is one of the main reasons why most people fail their drug test.

Drinking lots of water before the test will not help you pass the test. Many users believe they can cheat the test [2] by trying to dilute their urine before the test, but it has very little impact. I advise you not to try that method.

2 Types of Synthetic Urine 

There are two types of synthetic urine: liquid and powder. As the name suggests, synthetic urine is urine that is ready to use, while powder urine must be mixed with water before use.

1. Liquid Synthetic Urine Kit

Liquid fake urine is a synthetic product. You don’t need to add anything else to it. Just mix it, heat it up, and then use it on a drug test.


  • Because it is premixed, synthetic urine is extremely handy and simple to utilize.
  • You can’t be seen as you go through the process of producing your urine.
  • Since there are few complicated procedures to follow, you’ll have a low margin of error and, as a result, higher chances of success.


  • Liquid fake urine lasts for a shorter amount of time than powdered fake urine.

 2. Powdered Synthetic Urine Kit

Powdered synthetic urine is dehydrated synthetic urine that must be ‘passed’ as genuine. Using tap water with powdered fake urine is a major blunder that will not provide a valid sample on a drug test.

The fake urine sample is packaged in a vial that must be transferred to a larger container to combine and make the imitation pee. 

Typically, there’s enough in the vial to fill a gallon of fake pee, so measure your distilled water out according to the manufacturer’s recommendations. A fair amount of mixing and specific instructions are required when making your own urine, but the process is pretty straightforward.


  • Powdered synthetic urine forms into a foam that is identical to actual urine.
  • You’ll soon discover that it smells exactly like normal urine.
  • The shelf life of this synthetic urine is longer than that of liquid synthetic urine.
  • It’s a lot easier to store than a liquid vial.
  • It effectively replicates natural qualities since it is manufactured from real human urine.


  • It’s not as simple as liquid synthetic urine since you must combine the urine and then warm it up.
  • It’s a waste of a vital if you don’t follow the instructions precisely.
  • Due to the amount of mixing and measuring that must be done, there’s a greater risk of things going wrong.
  • If you do this at your workplace, it is more likely that you will be caught. You will definitely be noticed if you try this.

Ingredients of the Best Synthetic Urine Kits

A fake urine kit for a drug test is a product that might include anything from tiny plastic tubing to a fake color-matched penis as part of the delivery system. 

The best synthetic urine has no hazardous chemicals in it.

Synthetic urine was originally designed by laboratories to check their lab equipment in order to ensure it was working properly before evaluating genuine pee samples.

Here are some of the most typical components in fake piss:

  • Uric acid
  • Urea
  • Phosphorus sodium
  • Pure water
  • Potassium chloride
  • Creatinine
  • Sodium chloride

The best synthetic urine kits will include both urea and uric acid. All successful synthetic urines also include creatinine, which is a result of muscle metabolism. Most testers will look for a yellow color to make sure the sample isn’t too diluted. Some testers might also smell urine samples to see what they smell like.

Using Synthetic Urine Kits

The first and most important thing to remember about making fake urine is that it must appear genuine on a drug test. Whether it’s liquid or powder, the key issue is replicating the appearance of urine to help you pass a drug test.

1. Powdered Synthetic Urine Kits

The procedure of utilizing powdered human urine is more time-consuming than that of liquid pee. These fake urine kits come with a vial of powdered urine. The majority of the time, you’ll be able to make a full bottle of fake urine using the kit.

In order to create this synthetic urine properly, you’ll need to combine powdered urine with cooled distilled water in a bottle and vigorously shake it. The shaking will cause the required foam and dissolve the powder in the water.

Make sure you shake the rest until no more synthetic urine powder is left and you only see bubbles. Once this is the case, heat it up until it reaches 95 degrees. Before using the urine, simply shake once more.

The complexity of this task stems from the precise amount of water and heat needed to be achieved. Even a minor variation in measurements or temperature might corrupt the entire sample. As we mentioned before, the temperature of your fake urine is key.

2. Liquid Synthetic Urine Kits

A lot of people choose this synthetic urine over powder because it is a lot simpler to use before a drug test. You must open the vial and pour the entire contents into the collection cup. The container that the fake pee comes in will have temperature strips on the side, so all you need to do is make sure that it’s between 92-100 degrees.

The output will be much warmer than body temperature, so it is essential to ensure that you don’t heat it too much. If the tester suspects that the sample has been heated, they might reject it outright.

One thing to remember is that you should urinate a little before using the synthetic urine, as this will help lower the cup’s temperature.

Another thing to remember is that you should use gloves when handling the fake pee, as your body heat can also affect the temperature before the drug test.

4 Ways of Heating Synthetic Urine Sample

As we mentioned before, one of the most important things to remember when using a synthetic urine sample is that it must be at the right temperature. The vast majority of urine drug test procedures will check the temperature of the sample, as hot or cold urine can indicate that it’s not real. There are four ways to heat synthetic urine: microwave, hand warmer, body heat, and heating pads.

1. Microwave 

A microwave is all you need to warm up your fake urine before a drug test. If it’s still grossing you out, think about what could happen if you get caught.

When using a microwave, you must be careful and watch it closely. If it gets too hot, your synthetic specimen will be ruined. If it starts boiling, then you’ve overdone it. The perfect time would be no more than 10 seconds in the microwave. Check the temperature of the specimen with a temperature strip to be more accurate.

2. Hand Warmers

Hand warmers that you can buy in a box or package of three to five and carry around with you are called portable, disposable hand warmers. They claim to keep the heat going for roughly 18 hours. They’re more than likely the best way to heat your specimen.

Once you’ve mixed your synthetic urine combination, put it in a hand warmer and check the temperature on a regular basis. Keeping the sample near to your body is the best way to keep it from becoming too hot.

3. Body Heat 

With only your body heat, getting the ideal temperature takes considerably longer than with the other two procedures. If you have time, consider utilizing your body heat to warm up the sample.

It is ideal when kept on the skin and in the warmest parts of your body. 

The synthetic urine would be beneath the pants for males. Women may use the same approach or place it between their bra and skin for maximum effect. When ready to submit the sample during a drug test, use a stick to verify the desired temperature.

4. Heating Pads

Heating pads are electric warming pads that can be found at any drug store. They come in different shapes and sizes, but they all serve the same purpose: to generate heat. The pads will have an indicator light that tells you when it’s on, so there’s no need to worry about leaving it on for too long.

Use the pad on its lowest setting and place the container of synthetic urine on top of it. Check the temperature on a regular basis to make sure it doesn’t get too hot.

Using a pad is one of the most foolproof ways to heat up your specimen, but it takes a little longer than the other methods.

No matter which method you choose, check the temperature of your synthetic urine before submitting it during a drug test. 

Which Synthetic Urines Have Uric Acid?

Several brands of synthetic urine have uric acid in their formula to more closely mimic the composition of human urine. Some of these brands are:

  • Quick Fix Synthetic Urine
  • Sub Solution Synthetic Urine
  • Monkey Whizz Synthetic Urine
  • UPass Synthetic Urine
  • XStream Synthetic Urine

Tips and Tricks to Store the Synthetic Urine

If you’re going to use synthetic urine, you must know how to store it properly before a drug test.

Here are some tips and tricks to keep in mind:

  • Store the urine in a cool, dark place.
  • Make sure the lid is on tight so that it doesn’t leak.
  • Don’t freeze the urine, as this can ruin the sample.
  • If you’re using a pad, unplug it once the urine is at the right temperature.
  • Don’t overheat the urine, as this can also ruin the sample, and avoid direct sunlight.

These tips will help ensure that your synthetic urine is in good condition and ready to use when needed.

Signs of a Bad Synthetic Urine 

There are a few signs that you can look for to tell if your urine is terrible due to incorrect application of the instructions.

These include:

  • The sample is cloudy or discolored.
  • There is sediment at the bottom of the container.
  • The sample has an unusual smell.

Frequently Asked Questions

How Long is Synthetic Urine Good For?

Banner for "How Long Can You Keep It?"

High-quality synthetic urine brands can be good for up to two years, as long as it has not been opened. Once you open the bag and create the mixture, you have very little time to use it before your results can be compromised. Powdered urine could even last longer.

Can Fake Piss or Synthetic Products Be Detected Easily?

Yes, fake pee or synthetic urine brands can be detected easily, but it depends on a few factors. If you don’t buy quality synthetic urine, don’t store it correctly in its bag, and follow the instructions perfectly, of course, it can be detected.

Fun fact though, drug testing labs use synthetic urine to calibrate their urine screening equipment, so when used correctly, it is easy to trick the system. Just make sure you follow the instructions on the package EXACTLY.

How Many Ounces of Urine Do You Need?

By law, you are only required to submit two ounces of urine. Although this doesn’t necessarily mean that a nosey official won’t ask you to submit more than that. This could potentially be an issue if you only brought two ounces of fake pee, which is why we always recommend buying the bigger size, which is three ounces.

Is there Unisex Synthetic Urine Available?

Most synthetic urine kits are unisex, meaning they can be used safely by both girls and guys. Standard drug tests do not typically analyze for gender, meaning you are free and clear.

unisexActually, most drug test procedures are only looking for a few common elements in clean pee including pH levels, creatinine levels, uric acid, nitrate, urea, glutaraldehyde, as well as color, odor, and temperature.

What you DO need is a delivery system that’s made for your gender. If you’re doing an unsupervised assessment, it doesn’t matter – you can just pour the synthetic urine into a clean cup. But if it’s supervised drug tests, and you’re a male, you’re going to need a system like the reliable reliable Monkey Dong to fake the actual act of peeing.

Is There a Product Just for Women?

There are synthetic urine kits available on the internet that is advertised solely to women, but don’t be fooled — there is nothing outstanding or different about these products, except maybe for their price tag. As we said, the only thing that’s going to be different for the ladies is the system to fake the actual act of taking a whiz during a drug test.

Some brands have created fancy kits for dispensing pee discreetly, which are designed for males or females, but otherwise, there is no actual difference. We can’t drive home this point enough, though — you must get yourself a high-quality synthetic urine brand if you want to pass your next assessment.

How to Prepare for a Test Using Synthetic Urine?

To prepare a good synthetic urine kit for passing drug tests, it is crucial that you only mix the product right before you are about to drop your sample off at the lab.  If you can take the fake urine kit at home and then drop it off, place the mixture containing your premixed synthetic urine in the microwave for 10-15 seconds and use the heat activator or temperature strip that comes with the kit.

Store it in your pocket or bag, one that is big enough to hide a small warming pad discreetly, and then hand it off to the lab technician as quickly as possible for passing drug tests. Synthetic urine will cool off much faster than human urine, so keep this in mind. Usually, with the best synthetic urine brands that use a heating pad or temperature strip, you’ve got about 6 hours of leeway time.

What Are the Different Types of Drug Panels?

If you didn’t know, there are different types of drug panels when it comes to testing for different substances. It is good to know which one you’re going to be tested for so you can properly prepare for it. Here are the different panels and exactly what drug they test for:

7 Panel Urine Test 10 Panel Urine Test 12 Panel Urine Test
Marijuana Marijuana Marijuana
Opiates Opiates Opiates
Cocaine Cocaine Cocaine
Amphetamines Amphetamines Amphetamines
Benzodiazepines Benzodiazepines Benzodiazepines
Barbiturates Barbiturates Barbiturates
Methadone Methadone
Propoxyphene Propoxyphene
Quaaludes Quaaludes
7 Panel Urine Test
10 Panel Urine Test
12 Panel Urine Test
Now, having this information does make it seem a little bit more complicated than it used to be, but it does help you come prepared when to pass drug tests.

Is It Possible to Make Them Yourself?

Yes, it is possible to make them yourself, but it is not that easy. And to help you out a bit more, here is our full guide on how to make your own synthetic urine. Good luck!

But to summarize our take on it, we don’t think it’s worth it to make these things on your own. It’s harder than mixing powdered urine, and the shelf life could be dubious at best. Also, there is just too much risk for the reward, which is saving a couple of bucks. Do you honestly think that your job is not even worth that amount of cash? Yeah, definitely give it a long thought because you’re playing with fire here.

Does Synthetic Urine Expire?

Yes, they do expire. Even the best ones have a shelf life of about 2 years. And that is if you keep them properly stored with the right temperature and all. Once they have hit the expiration date, they are no longer useful because their integrity has been compromised and that will cause you to fail your test.

If you’re thinking about powdered synthetic urine, they have a longer shelf life compared to liquid synthetic urine, so just watch for that!
