Quick Fix Synthetic Urine is a laboratory grade synthetic urine that is used to calibrate urine testing machines. This synthetic urine contains all of the ingredients found in natural human urine and is balanced for pH, specific gravity and creatinine. Infact, every batch of Quick Fix is tested before it leaves the lab! This ensures that you get the best sample possible! Quickfix is unisex, meaning it will work for both male and female. Unlike dehydrated or powdered urine the QuickFix is pre-mixed, making it easy to use in any last minute situation. Quick Fix takes only about 15 seconds to prepare!
