Collection: Synthetic Pee 3oz Kits

Every Upass synthetic pee kit is a complete 3oz system: premixed synthetic urine with the full chemical profile (urea, creatinine, balanced pH, correct specific gravity), an adhesive heating pad, and a temperature strip mounted on the bottle. Nothing to mix, nothing to buy separately. Warm it, check that the strip reads 90–100°F, and it's ready.

The 3oz volume matters: it's enough for standard sample cups with margin to spare, while staying compact enough to warm quickly and hold temperature with a single heating pad. Safeguard Labs has manufactured the original Upass formula for over a decade, batch-testing every production run. Order by 2 PM PT and it ships the same day in plain packaging.
