A reagent kit will not tell you your dose, but it will tell you whether what you have is roughly what you think it is, and that single check heads off the worst surprises.
What we rate
How clearly the colour reactions read, how long the reagents keep, and how easy the kit is to use in bad lighting at the end of a night. The best kits are foolproof; the worst leave you squinting.
What it will not do
Measure purity or milligrams. Pair it with a scale and start low. Our testing guide walks through how to read a result.
Information, not medical advice. Threshold does not promote or encourage MDMA use. This exists so that people who make their own choices can make safer, better-informed ones. It is not a substitute for professional care.
