Best Synthetic Urine for a Drug Test

We’ve all heard the stories. A woman or man goes into a urine screen with a friend’s “clean” urine and is summarily fired for testing positive for other drugs never used; or is advised to see a doctor for a medical condition they don't have. Although the stories about men congratulated for being the first pregnant male known to science are exaggerated, there is truth to the inherent risks of using adulterated urine from other persons.

All joking aside, your urine sample can be the difference between a job promotion or standing in line at the unemployment office. Many of us are just recreational smokers, and it seems extreme to have your life turned upside down because of a weekend imbibe.

So, what can you do to give greater assurance you’ll pass that urine screen if you are faced with a random urinalysis? Consider synthetic urine.

Synthetic urine is simply urine created in a laboratory that looks, smells and has the chemical makeup of biological urine.

Synthetic urine emulates the key chemical structure of clean human urine, which can then be used in research, urinalysis testing equipment calibration, and other domestic products. Of social importance, it contains the composition structure necessary in drug testing. It does this by imitating the color, smell, composition and chemical properties of real urine.

So, what is the key construction of synthetic urine needed to pass a urinalysis, you may ask? All of the major components of natural urine must be found in synthetic urine to be effective. These include (among other things) creatinine, uric acid, urea, ammonia, and sulfates. Even the pH level and specific gravity in “real” and synthetic urines are nearly identical.

Synthetic urine comes in two main forms: pre-mixed liquid solution; and dried powder. Both forms have both pros and cons that you should consider. We will look at the pros and cons later.


The simple answer is “Yes, it works”. Synthetic urine has some very good benefits. First, it remains stable at room temperature. Second it is easy to warm it to body temperature. Third, it is easier to store. Fourth, it lasts longer than human urine.

That all said, synthetic urine is an effective way to pass a urine test when you're at risk of testing positive. However, mixing synthetic urine requires knowledge and skill Many synthetic alternatives are adulterated and unreliable. While some can even be detected by a lab, others just fail to work.

That’s why it is vitally important that you choose a legitimate manufacturer and a product that you know will be 100% reliable.


How do test labs detect synthetic urine? According to the American Toxicology Institute, the answer is almost always by the color, temperature and foaming of the specimen.

Color: Biological urine has a color range that can be detected by a trained testing agent. According to the Mayo Clinic, Urochrome is the chemical in urine that gives it color. Urine can vary from very pale yellow to a deep amber hue. Although such things as dehydration, medications and food can affect the color of urine, urine is always colored. The highest grade synthetic urines will duplicate the shades of yellow or green in normal urine.

Temperature: After only a few seconds outside the body, the temperature of urine will begin to drop off. So, the testing lab will immediately test urine for its temperature. The normal temperature of urine fresh out of the body is in the range of 90°F to 98°F. Therefore, if the synthetic urine you use is outside that range, it will be red flagged.

Foaming: Natural urine contains albumin, which is what gives it the foaming quality as it leaves the body. Before offering your sample, it is always wise to give the vial a shake just to create bubbles. The best products will contain the needed albumin component to cause the foaming.

When synthetic urine is used correctly, it is almost impossible for a testing lab to detect it as a counterfeit urine. This is because the best synthetic products so closely replicate human urine.

If the 3 elements above fall outside the testing parameters, then according to the American Toxicology Institute, the sample is further verified by other constituents that often are associated with the use of adulterated urine. These constituents are often identified in low quality synthetic urines on the market that include:

  • Albumin
  • Ammonia
  • Creatinine
  • Glutaraldehyde
  • Nitrite
  • Oxidants
  • pH Level
  • Specific Gravity
  • Sulfates
  • Urea
  • Uric Acid


Powdered Synthetic Urine:

  1. 1
    Pour your powdered urine from its holding vial into the larger vial or bottle.
  2. 2
    Slowly fill the vial with water to the very top.
  3. 3
    Screw the cap on tightly and shake until the powder is fully dissolved.
  4. 4
    Open the heater package and remove the paper.
  5. 5
    Apply the heater to the backside of the vial (opposite to the temperature strip).
  6. 6
    Before undergoing the urine test, check the temperature is between 91F and 99F.
  7. 7
    Let if flow into the collector cup.

Liquid Synthetic Urine:

  1. 1
    Open container top.
  2. 2
    Microwave liquid urine for approximately 10 seconds.
  3. 3
    Close container top and shake liquid.
  4. 4
    Check temperature is 94F to 99F (heat more or let cool to reach temperature).
  5. 5
    Tape or rubber ban the heating pad to the container.
  6. 6
    Right before test, verify temperature is between 94F to 99F.
  7. 7
    Shake liquid.
  8. 8
    Let it flow into urine collector.

Here's a good video on mixing powdered synthetic urine.


The best synthetic urine products contain heating systems or heating pads to maintain the urine’s proper testing temperature until the specimen is needed. That is what we recommend and why it is so important to utilize a credible product that offers the proper temperature testing system.

In the alternative, consider the following:

  • Microwave
  • Hand Warmers
  • Body Heat

Microwave Microwave heating can be a quick fix to bring your synthetic urine to the proper testing temperature. Most manufacturers suggest that heating the liquid for up to 10 seconds is sufficient time. Overheating could cause the specimen to be damaged, so keeping it under 10 seconds and then placing it near the body to maintain the temperature is a good option.

Hand Warmers Small portable packets of hand warmers can be purchased at most stores. They can maintain a heat source to keep your urine sample at the correct temperature for hours at a time. Since they are small, you can attach them to your urine sample easily and out of sight. It is necessary to use a temperature strip before providing the sample to assure that the temperature is at the correct temperature.

Body Heat Use the heat of your body to warm and maintain the temperature of the synthetic urine sample. It is recommended for men to place the sample in your underwear near your genitalia, since you emit the most heat there. For women, inside the bra or underwear, next to the body, is optimum.

Always be sure to use a temperature test strip or thermometer to confirming the proper temperature before taking the urine screen.


Although synthetic urine is available in both dried powder and pre-mixed liquid solutions, they all have expiration dates. All synthetic urine, whether a pre-mixed liquid or dehydrated powder, has a shelf life of from months to up to three years.

Quality synthetic urine products will contain an expiration date directly on the product itself. Look for it and adhere to it! It’s a good idea to replace any unused kits that have been lying around or unused past the expiration dates. A simple rule of thumb, periodically replace your product with a fresh package – whether powdered or liquid – to assure valid results in your testing.

Synthetic urine, for optimal shelf life, should be kept in a cool and dark storage. If your kit has been exposed to excessive heat or sunlight, you should discard it.


It really is a matter of preference whether you use powdered or liquid synthetic urine. But how each compares continues to be a topic of debate. But we hope the following gives a brief synopsis of both the pros and cons for you to further deliberate.

Liquid urine, as we discussed earlier, is a liquid created to mimic the color, smell and chemical constituents of clean human urine.

Powdered urine also is a dehydrated powder that, when reconstituted with water, also will form the color, smell and chemical properties of clean human urine. Our top choice, ClearTest® also claims that its powdered urine is actually drug-free dehydrated human urine, so it will best mimic your own biological urine in a laboratory drug test.

Powdered Synthetic Urine


  • Looks, smells and foams like real urine
  • Dehydrated human urine best mimics your own urine
  • 100% test effective
  • Retains all the natural properties of human urine
  • Longer shelf life
  • Easy to store


  • Not convenient to use
  • Requires mixing
  • Directions must be followed exactly
  • Higher risk of effectiveness

Liquid Synthetic Urine


  • Pre-mixed and easy to use
  • Convenient
  • Little risk to effectiveness


  • Shorter shelf life


Every ingredient found in synthetic urine is designed to be tested to meet the specifications of color, smell and components found in authentic human urine.

Distilled Water

Urine contains about 95% water and it is important to use distilled water to keep adulterants out of the composition. So, effective synthetic urine will use distilled water instead of tap water.

Creatinine Level

Creatinine is a derivative of creatine phosphate, which is metabolized by your muscles. Creatinine is included in fake urine so that it appears normal. Creatinine levels will test at low levels, otherwise it will be assumed excessive amounts of water have been consumed to trick the urinalysis test.

Albumin Powder

Albumin is a protein found naturally in urine and is what causes urine to foam when fresh out of the body. Albumin powder, either derived from bovine serum or egg products, is added to urine to reproduce this behavior.

Uric Acid

Normal human urine contains uric acid, so it is obvious that a lab will look for it in a test sampling. Uric acid is a chemical that is present from the body breaking down certain substances called purines. Uric acid typically dissolves in blood and then travels to the kidneys where it is excreted. Since it is always found in human urine evacuation, it must be present in the urinalysis sample. The best synthetic urine will contain this product on the labeling.


Synthetic urine isn’t just for use in passing a drug or nicotine screen. There are a plethora of unexpected uses for synthetic urine, from photography to cosmetics to plump skin. So, a brief listing of alternative uses for synthetic urine follows:

  • Calibrating Urinalysis Equipment
  • Alternative Medicine
  • Education Training
  • Scientific Research
  • Cosmetic and Skin Care Products
  • Wildlife Deterrent for Lawn & Garden (Repellent for Deer, Rabbits, Dogs, etc.)
  • Wildlife Encouragement (Hunting, Research, Photography, etc.)
  • Human Scent Mask
  • Salesperson Prop
  • Adult Entertainment
  • Product Testing (Cleaning Agents, Hygene Products, etc.)


The current demand for synthetic urine has risen over the last few years, which means profits for many. Increased market demand always leads to the introduction of counterfeiters and the “quick buck Joe” who is selling adulterated products.

So, the answer to the question is a resounding "Yes". Unscrupulous companies and adulterated products will only place your urine screen at risk of failing the test. So, do your research and don’t be swayed by cheap prices and false promises. Buy direct from reputable dealers and forget the ebay discount.

That’s why we did the research and found our Top 3 synthetic urine products.

The Best Synthetic Urine to Buy is REAL Human Urine!

Lowest Price – —>

sythetic urine kit

If you like to get guaranteed results, try the TestClear Powdered Urine Kit. Unlike the Clear Choice Sub-Solution, the Powdered Urine Kit is made of real human urine. It comes with one vial for powdered urine, another vial for medical transport, a temperature strip, and two heaters.

If you haven’t read about Test Clear and their product line, do so on this page.  

Urine Simulation with Powdered Urine Kit

  • This is the best selling powdered urine kit for a reason.  It’s a “REAL” urine simulation product that will pass any level of sophisticated drug testing.  Don’t rely on fake urine when the company drug testing calls for something to work 100% effectively.

How to Use Fake Urine (Although It’s Real)

  • 45 minutes to one hour prior to your test, mix the powder with water (room temp) and place the heater on the side of the vial without the temperature strip.
  • You will notice this looks, feels, and smells like real, drug-free urine produced by humans.  Know that it’ll pass the required testing levels because it’s real.
  • All you need is water!
  • The urine kit holds 50 ML in the vial, and the heater will have a duration of six hours, and the kit comes with full instructions.
  • The heater will need about 45 minutes to have water that is room temperature get to 90 – 99 degrees.
  • The included temperature strip is very accurate, and entirely reusable.

Buy extra heaters when you buy the human urine kit, just in case you have an issue with your test and it’s delayed.

While this will help you pass any urine test, this is also a great gag gift or bed wetting prank.  Although, we like to take work seriously and focus on what it’s intended for, which is passing urine tests for marijuana.
