Collection: Upass Fake Urine

Upass is lab-formulated fake urine made by Safeguard Labs, the original manufacturer behind the Upass 8.4 formula, trusted across the United States for over 15 years. Every bottle here ships direct from the manufacturer, so you get current-batch stock and guaranteed authenticity that no third-party listing can match.

Each kit arrives premixed and ready to use:

• 3 oz bottle of Upass 8.4 fake pee formula
• Air-activated heating pad
• Adhesive temperature strip
• Simple step-by-step instructions

Unlike bargain fake pee and synthetic pee products, every Upass batch is lab-tested for consistency. The formula carries a complete chemical profile of balanced pH, realistic specific gravity, creatinine, urea, and uric acid, engineered to simulate the look, foam, and composition of human urine.

Upass fake urine is intended for lawful uses: calibrating urinalysis equipment, scientific research and education, product demonstrations, pranks, and adult novelty or fetish applications. Buyers are responsible for compliance with their state and local laws.

Order by 3:00 PM PT, Monday–Friday, and your kit ships the same business day. Start with a single kit or save with our 2-pack and 3-pack bundles. Every sealed bottle carries a 24-month shelf life.
