Step-by-step guides to checking what is actually in a sample. Which reagent suits which substance, how to read a colour change, and where reagents stop and purity testing begins.
How to detect caffeine?
Caffeine is the single most common cut in European stimulants. It is also one of the easier adulterants to find, if you use the right test.
How to test LSD derivatives?
Lysergamide analogues are legal in many countries and increasingly common. They do react with Ehrlich and Hofmann, just not on the same timetable.
How to detect PMA / PMMA / PMEA?
PMA and PMMA have killed people who believed they had taken MDMA. Here are the reagent reactions that separate them, compound by compound.
How to test LSD quantity?
We checked whether the Hofmann test, generally used to confirm the presence of “acid,” could be used as a reagent to test the amount of LSD. It turns out that yes, so when you buy a PRO test for identifying LSD you get a free test for quantity.
How to detect meth/amphetamine mixed in MDMA?
When a sample has more than one ingredient, a reagent mostly shows you the strongest reaction. Here is how to work around that and find the stimulant.
Eutylone reagent testing results
Eutylone has been missold as MDMA since 2019. Unlike most cathinones, its reagent results are distinctive enough to catch it.
1P-LSD does not turn Ehrlich purple
1P-LSD, one of novel lysergamides, is known to not react with the Ehrlich reagent within the expected time frame (minutes). Despite that, some users report that their samples do in fact turn Ehrlich reagent pink / purple.
