Artificial urine, also known as synthetic urine, is a carefully engineered substitute designed to closely mimic the composition and properties of real human urine. This laboratory-created solution contains essential components like urea, creatinine, and uric acid, precisely balanced to match the typical characteristics of genuine urine samples. Synthetic pee is invaluable for calibrating laboratory equipment, educating students, and developing reliable control samples for research and quality assurance. Its unique formulation allows it to effectively simulate normal human urine, making it a versatile tool across scientific and educational settings.

Beyond professional applications, fake piss has gained popularity among those seeking privacy in situations requiring urine testing.
