Pre-mixed liquid: Upass, like other brands such as Quick Fix, comes ready to use in liquid form, eliminating the need for mixing.
Chemical composition: It is formulated to closely match the chemical composition of real urine, containing substances like creatinine, salts, and yellow coloring.
Temperature sensitive: Upass is temperature sensitive, and maintaining the correct temperature (typically between 90°F and 100°F) is crucial for a believable sample during drug testing.
Temperature strip: The bottle includes a temperature strip to help users monitor the temperature.
Heating methods: Instructions for heating often involve microwaving or using a heating pad to bring the urine to the desired temperature.
Concealment: Due to its intended use, Upass is often packaged in a small bottle to facilitate discreet transport and concealment.
