The gold standard in synthetic urine. Over a decade at the top. 💛

Synthetix5 has, for more than a decade, been the number one trusted company for synthetic urine kits — evolving over the years to include improved accessories and consistent batch-to-batch quality. Although crafted in a laboratory, this blend is nearly identical to real human urine — making it ideal for fetish play, role-play scenarios, and calibrating urine testing equipment.

🧪 Formula

Synthetix5 contains creatinine, urea, uric acid, and many other naturally occurring compounds — with the proper balance of pH and specific gravity to deliver the most lifelike experience possible. The liquid has been incubated for 48 hours, which eliminates sedimentation and separation — no shaking required.
