Common questions

What is fake pee?
Fake pee (also called fake urine, synthetic pee, or synthetic urine) is a laboratory-made solution that simulates real human urine. Upass has been manufactured by Safeguard Labs since 2009 for lawful uses: calibrating and validating urinalysis equipment, scientific research and product testing, medical and laboratory education, demonstrations and pranks, and adult novelty applications.

Is Upass sold on Amazon, at Walmart, or in smoke shops near me?
No. Upass is sold direct from upassurine.com, the only authorized online channel. Kits found on marketplaces or in stores are not authorized and counterfeits circulate through those channels. Buy direct to be certain of what you are getting.

How do I know my kit is genuine?
Every authentic Upass box is printed with a lot number and expiration date next to the UPC. No lot number means it is not from us.

How long does a sealed kit keep?
Sealed bottles carry a 2-year shelf life, with the expiration date printed on the box.

Who makes Upass?
Safeguard Labs, the original manufacturer, in continuous production for over 17 years. Independently lab tested, and every batch is quality-checked in-house. 127 verified customer reviews with a 5.0-star average.
