Reagents
Is Froehde reagent reliable?
Reliable, and built for confirmation. What agreement with Marquis proves, and what a clear result rules out.
Reagents
Is Liebermann reagent reliable?
It excludes more adulterants than any other reagent, and it turns orange for a reason most people miss.
Reagents
Is Mecke reagent reliable?
Yes, and it is the one to pair with Marquis before any other. What it confirms, and what a pale result rules out.
Reagents
Simon’s or Robadope, which one do you need?
One reacts with secondary amines, the other with primary. That single difference is what separates MDMA from MDA and speed from meth.

How to read a reagent colour chart
Chart hunting is over. Build the comparison you need in the DrugsPRO app, share it as a link, and read the reaction photos instead of matching a printed colour.
Reagents Benzocaine Cathinones Cocaine Ketamine Mephedrone MMC Morris Scott
Is Scott’s reagent reliable?
Scott is the best known cocaine test and one of the least specific. The caines give an identical result.
