Choose the best reagent test: to identify other substances that could be present in an MDMA sample, use reagents that with adulterants turn to a darker color than with MDMA. Find all the reference information in instructions, color charts, videos & apps.
Reagents presumptively indicate PRESENCE, but not PURITY or QUANTITY. A positive or negative test result does not mean that the substance is safe. No substance is 100% safe.
