Crafted by Safeguard Laboratories, every bottle of UPass Urine comes with 3oz of laboratory grade synthetic urine for you to use in all your fetish adventures. Because it contains all the same chemicals and compounds typically found in a sample of human urine, UPass Urine perfectly mimics real pee. However, since it’s guaranteed to be free from all harmful toxins and bacteria, it provides a safer alternative for all your piss play activities. If you’re into urine, grab a bottle today and you’ll see how amazing this liquid gold really is!  Save 25% by purchasing the Upass Value Pack - buy 3, get 1 free!

Each bottle of UPass contains 3oz of premixed synthetic urine that comes loaded with all the ingredients your own urine has - like uric acid, creatinine, and urea. UPass Urine is even balanced so it has the same pH level and specific gravity (density) of actual, human pee. In fact, it’s so close to the real thing, many lab technicians will use UPass to help them calibrate their urinalysis equipment. That’s right! Although UPass is only intended to be used for novelty and fetish purposes, it’s so close to actual urine, it could even pass for pee in a urine testing laboratory!

Who doesn’t love a little wet-sex action? But, wait! Did you know that human urine can transmit harmful diseases to your fetish friends? When you play with UPass instead, you’re staying safe by not putting your partner(s) at risk. Because UPass Urine doesn’t contain any of the toxins or bacteria you’d normally find in human urine, it’s cleaner and safer - while still being completely realistic!

You can use your UPass Urine anywhere you need a substitute for your own piss. However, the most common use is to simulate a golden shower experience. To do this, all you have to do is heat up the liquid to body temperature. Simply shake the bottle of UPass, remove the cap, and place in the microwave for 10 seconds (or until the temperature strip on the bottle reads between 94 and 100 degrees). Replace the flip-top cap and you’re good to go! If you’ll be needing to keep your fake pee at body temperature for awhile, you can use the included hand warmer to keep your sample warm for up to 8 hours. Just open the warmer, shake to activate, and then strap it to the bottle of UPass using the included rubber band. Make sure to put it on the side opposite the temperature strip, otherwise it can cause the strip to give you a false reading. When you’re ready to dispense your synthetic urine, give the bottle one last shake and check that the temperature strip reads between 94-100 degrees. Open the cap and empty your fake pee wherever you want it most!

Every bottle of UPass has been 100% pretested in the Safeguard Laboratory and has never failed! It’s guaranteed to pass for piss wherever you need a urine substitute. Get yourself a bottle today and feed your kinky side ;)
