Upass is the synthetic urine brand sold directly by Safeguard Labs, its manufacturer since 2009. Developed in the United States, the product is presented as a laboratory-grade control solution that simulates key chemical and physical properties of natural human urine. Its formulation includes water, creatinine, urea, uric acid, and other compounds, with attention to pH, specific gravity, color, clarity, scent, and foam behavior.

Upass is intended for controlled professional and educational applications, including laboratory equipment calibration, academic instruction, lab training, product development, and scientific research. The pre-mixed, unisex solution is sealed, portable, non-biological, and does not require refrigeration. The company states that it is batch-tested for consistency and has a shelf life of up to two years when stored in a cool, dry place.

The available kit includes three ounces of solution, an air-activated hand warmer, a temperature strip, and a dispensing cap. Upass is sold through the official online store, which also provides usage guidance, customer support, wholesale information, and shipping options. Orders placed by 3 p.m.
