Order Clean Human Urine Each of our sample of real human urine for sale undergoes GC (gas chromatography) and MS (mass spectrometry) testing—two procedures that are considered the gold standard of urinalysis. Although typically used to confirm a positive enzyme multiple immunoassay test (EMIT), we skip this procedure for GC and MS. Our reason for doing so is simple: if it passes a properly administered GC and MS testing, it only means YOU CAN’T FAIL.
