Description  more details

If you need a product that can accurately replicate urine, then the powdered urine kit is the ideal solution for you. It is widely regarded as the top choice for many individuals, and we strongly recommend it to you as well, regardless of the complexity of your experiment. The kit contains all the necessary chemicals, including uric acid, to simulate urine effectively.

  • To prepare for your experiment, mix the powdered natural urine with room temperature water (70F/21C) at home. About an hour before your experiment, arrive near the facility and attach the heater to the vial opposite the temperature strip. It will take approximately 45 minutes to reach the desired temperature, so keep an eye on the temperature strip and begin your experiment once it indicates the correct temperature (90-100F/32-37C). 
  • Our urine kit made of powder is specifically designed to resemble drug-free human urine in terms of appearance, scent, and chemical properties, enabling you to pass any test confidently. Our powdered urine is free of toxins and serves as a standard for calibrating drug testing machines, making it the most dependable product available in the market.
  • The kit includes a 50-ml plastic medical vial, drug-free powdered urine, an air-activated heater that lasts up to six hours, a temperature strip, and an instruction sheet with helpful hints and tips. Please note that you will need to provide your own water.
  • The plastic transportation vial can hold up to 50 ml, and you must submit at least 45 ml for your sample to be valid. We provide you with an extra 5 ml, but if you need more, you can add up to 25 ml of extra water (totaling 75 ml). Adding more than 75 ml of water may result in a diluted sample. The temperature strip is highly accurate, reusable, and of the best quality in the kit so that you can be sure of the exact temperature at all times. 
  • Extra heaters are available for purchase in case the experiment is delayed.
  • Additionally, a digital thermometer can be purchased, which some users find helpful for obtaining a wider temperature reading. For experiments that do not follow standard testing guidelines, an extra 15 ml vial is available. 
  • You can dilute our synthetic urine with 50% more water (25 ml) without any adverse effects. Our powdered urine is toxin-free and used to calibrate drug testing machines, making it the most reliable product on the market. It also makes for a great gag gift or bed-wetting prank.

Product Details

What Comes in the Testclear Powdered Urine Kit 

  • One vial containing powdered urine
  • One 50 ml plastic medical transport vial with a blue lid
  • One temperature strip
  • Two air-activated heaters


  1. Pour the powdered urine in the small vial into the larger 50 ml tube.
  2. Slowly fill the tube with water to the very top, screw the blue cap on tightly and shake until the powder is completely dissolved.
  3. 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.
  4. Before conducting your experiment, verify the temperature is within the correct range (90-100F/32-37C).

Tips and Tricks To Pass the Urine Drug Test

Drug tests are given following court cases or to protect the interests of public safety on a job site. The last thing you need is for a urine sample to cost you your job, send you back to the courthouse, or keep you from parole and all the indignities and emotional distress that come with these situations. Still, it's important not to commit serious ethical violations, such as using this tester to get around medical screenings or a drug screening for recent drug use when you're performing safety-sensitive duties where a falsified tox screen could result in injuries. For example, the U.S. Department of Transportation (DOT agency) has serious penalties for being intoxicated on the job, which may result in losing your commercial driver's license.

We must stress that job-related or legal penalties aren't the only reason you shouldn't use substances that could affect your judgment or performance while engaging in safety-sensitive duties. Being under the influence can have dire effects on your reaction time, for example, leading to dangerous accidents, especially when driving or operating machinery. This is true whether the substance is legal or not.

With that covered, here are some tips for using our powdered urine kit correctly:

  • Always call or email before your experiment if there are any questions. Don't guess; ask. - please reach out to [email protected] or our live chat

  • Before conducting the urine test simulation, you must verify that the urine temperature is between 90F and 100F/32C and 37C. Any sample outside that temperature could cause an invalid experiment, unintended laboratory test results, or anomalies.

  • We suggest you start with room temperature instead of hot or warm water because the heater we give you brings the water up to the correct temperature range on its own. Use one heater unless you want to get to the proper temperature faster.

  • It is not broken if you do not see any reading on the temperature strip. The urine is either too cold or too hot. The temperature strip is highly accurate, reusable, and the highest-quality component in the kit.

  • If the urine is too cold, be patient and let the heater raise the temperature. If the urine is too hot, remove the cap and heater and gently blow on the urine until it comes into the correct range.

  • Practice cooling the water. Take the tube alone, go to the sink, and put it in hot water, driving the temperature off the scale above 100F. Gently blow on the liquid until the rainbow temperature indicator comes into the 90- to 99-degree range. This does two things: It lets you see the rainbow indicator on the temperature strip and gives you experience bringing the temperature down, just in case the temperature rises above 100 degrees.

  • Be sure the heater is not too close to the temperature strip, or the strip will measure the heater instead of the water. Use rubber bands or adhesive tape for a snug fit between the heater and tube.

  • Unless the urine is too hot, do not take the heater off the tube, or the temperature will eventually fall out of the required range of 90 to 99 degrees.

  • Don't jump the gun. These heaters are single-use, so be positive about when your 10-panel drug test will take place before preparing the kit.

  • If your experiment requires more than 50 ml, take a small vial of water to dilute the sample to the minimum level of 75 ml. Be careful not to affect the temperature too much.

  • After the urine is ready, here's how to conceal it: Women can use the bra area or adapt to the common method men use: wearing two pairs of briefs or tight underwear and slipping the tube between the layers. If the tube is in a warm place against the body, the temperature should remain within the correct range for about 30 minutes.

  • Extra heaters are available at the time of purchase. They are highly recommended in case the test gets delayed.

  • A digital thermometer is also available at the time of purchase. Some people find providing a wider temperature reading helpful than the strip can. This option is highly recommended for first-time users who need to conceal illicit drug use.

  • An option for extra vials (either 50 ml or 15 ml) is handy when the extra volume is needed. Technically, you only need drops to conduct your experiment, but extra volume is useful to impress the audience or send a strong message. You can dilute the powdered urine we give with 50 percent more water (25 ml) without causing any adverse effects.


Is Powdered Urine Real Urine?

The kit contains powdered urine with real, drug-free human urine qualities. This urine in powdered form has uric acid and other compounds in authentic human urine. It will behave the same as a normal, clean urine sample in-home tests and when applicants or those in a drug-court program go to take their tests. If it is used correctly, the powdered urine sample will avoid a positive test result and conceal the use of illicit substances like THC, opiates, synthetic opioids, stimulants, and others. It will also behave accordingly for any experiments performed for health care, the creation of medicine, or similar purposes.

The powdered urine kit also differs from liquid synthetic urine or fake pee advertised in other fake urine kits. Such synthetic urine is made using chemicals and is typically used to test the effects of urine on bedding, diapers, and other products that are likely to come in contact with it. We don't recommend using such a product for specimen validity testing or tests detecting a drug's presence, as it may produce a false-positive result.

How Do You Use Clear Urine Powder?

Follow these steps to use the powdered urine kit for your experiment, simulation, or pre-employment drug test:

  1. Pour the vial of powdered urine into the collection container tube included in the kit. 

  2. Stick the temperature strip to the tube, which also comes with the kit.

  3. Fill the tube with water that reaches the top of the container and put the cap on tightly.

  4. Shake the tube to dissolve the powdered urine.

  5. Stick the heater to the backside of the tube.

  6. Verify the temperature and submit.

How Do You Pass Fake Urine for a Drug Test? 

This powdered urine kit is ideal for unsupervised drug tests. Confirm the testing details to make the necessary preparations for the urine drug test at home or in the facility’s bathroom. Ensure the urine sample is the correct amount and within the right temperature range to be a valid specimen. 

Will powdered urine pass a government or court-ordered test? 

No. Not only is using powdered urine to falsify a supervised drug test, government tests, or court-ordered test 

Can a powdered urine sample be saved if I don't use it the day it was mixed?

Yes, as long as it's used within 72 hours. This is the maximum amount of time the sample can be refrigerated, and you'll need to reheat it using the original process. Reheating more than once or attempting to use the kit after 72 hours will not produce the desired results.

Is the powdered urine kit a way to get clean of drugs?

No. As mentioned, the powdered urine kit is not meant for supervised drug tests, nor does it have anything to do with detoxifying your body. If you wish to detoxify your system, you must purchase one of our detox programs. Once your system is cleansed using these products, you can remain clean of drugs if you avoid further exposure.
