Protect your privacy and medical history with Quick Fix Plus synthetic urine - the same great product in a larger 3 oz bottle.

Quick Fix is the original and best premixed synthetic urine available. Our patented formula is a laboratory created version of human urine. Specific gravity, uric acid, PH, and creatine are all at the right levels. It makes for the perfect control urine sample to calibrate drug testing equipment or for other scientific uses.

This 3oz version of our synthetic urine kit includes everything you need and can be ready to go in minutes.



Our synthetic urine was created in a state of the art laboratory by a biochemist. With our patented Biocide Protection, you can rest assured that Quick Fix fake urine will be fresh and free of bacteria. It's your very best choice when it comes to a clean urine sample.

Our easy to use synthetic urine kits contain everything you need to simulate real human urine. It is premixed and ready to go within minutes. We even include a heat pack and temperature strip to ensure the product is between 90-100°. This is the temperature range that real urine comes out of the human body.

Quick Fix 6.2 fake urine is extremely good at mimicking human urine. Most people can't tell the difference between the real stuff and our fake pee. Perfect for pulling a pee prank on an unsuspecting friend!

Millions of men and women have used Quick Fix 6.2 with success for urine tests. It is the most trusted name in synthetic urine.


Spectrum Labs has designed Quick Fix clean pee from the ground up to have all of the normal stuff found in clean urine. We are also the only synthetic urine with Biocide Protection. Quick Fix is Pre-Mixed, meaning you’re not left doing chemistry experiment before using it. No need to mix heat activator and powders with water just to pray that you got it right. Simply heat in a microwave for 7-10 seconds, shake the hand warmer and you’re good to go.


It is extremely important that your control sample contains Biocide Protection. Our patented formula kills and prevents microbial growth. This means that our synthetic urine will stay fresh for months, even after reheating.

Fake urine without Biocide will go bad fast. When urine is exposed to bacteria, it begins to break down!

Most rip off products don't contain Biocide. They are prone to going bad often before the end consumer receives their package in the mail. Poor UPS, having to deliver spoiled urine. Yuck!


Not all synthetic urine is created equal. Most cheap knock off urine serves only to rip off the end user. Spectrum Labs actively goes after these counterfeit products. We have successfully won multi million dollar judgments against individuals that have infringed on our patented formula. The biggest way to avoid counterfeit products is to buy directly from us, the manufacturer.

Quick Fix is such an innovative product that it has many uses and applications. Here are a few!


Quick Fix has a stable PH level. It is perfect for the calibration of dipstick PH strips and drug testing. You could also use QuickFix to calibrate a hydrometer due to its stable specific gravity.


We're not here to kink shame anyone. What you do in your private life is your own business. But if you're into that sort of thing in the bedroom, make you use clean pee. So many diseases can be transferred via human body fluids, it's important to play safe with fake pee.


Are you looking to simulate real human urine for product testing? Diaper manufacturers can use our synthetic product to get an idea of how real urine would affect their products. Cleaning chemical companies can use Quick Fix to demonstrate the effects of cleaning solutions on human urine. The possibilities are endless.

This product has been issued multiple patents by, and is afforded the rights and protections of, the United States Patent Office. U.S. Patent No. 7,192,776 and U.S. Patent No. 9,128,105.


Activate hand warmer prior to heating up Quick Fix® Plus (may take 30-45 minutes for hand warmer to heat up).

Shake the Quick Fix® Plus bottle and microwave on high for 10 seconds. The temperature strip should display a green dot in a range of 94° – 100°F. If the bottle feels warm in your hand, but is not showing a reading on the temperature strip, the synthetic urine is overheated. Simply let it cool down gradually until you see a reading on the temperature strip. If the synthetic urine temperature is below 94°, heat again in the microwave for a few more seconds until you see the green dot on the temperature strip between 94° – 100°F.

Now attach the hand warmer with tape or rubber band to the back of the bottle, opposite the temperature strip. This will provide prolonged heat, keeping the bottle temperature near 100°F for approximately five hours.

If you can’t microwave the Quick Fix® Plus, simply attach the hand warmer to bottle at least 1 hour prior to your test. Shake bottle before and after heating and prior to pouring into cup.

If your product remains unused, it can be reheated repeatedly as needed.
