Drug Purity Report #33/26
Welcome to “last week on drugs”, a PRO Test series dedicated to reporting on drug-market purity. This week: doppelgänger Ecstasy pills, pills containing more than one stimulant, and continued diversity among cathinone samples.
Caution: warnings are not limited to compounds mentioned in this post. All published laboratory results are warnings. No psychoactive substance is 100% safe.
Data fatigue is real, so here is the gist of what is worth knowing.

Red TikTok pill tested in Austria. Pills with the same appearance were found to contain either MDMA or caffeine.
Doppelgänger Ecstasy pills
Every pill should be treated as different. The latest red TikTok and blue Punisher pills found in Austria illustrate why: half of the tested samples contained MDMA, while the other half contained caffeine.
A weak effect from a caffeine pill may encourage someone to take more and overestimate their tolerance, increasing the possible risk of an accidental overdose if another pill contains MDMA.
Multi-stimulant pills
Pills containing both MDMA and caffeine were found in Austria, including another type of blue Punisher tablet.
MDMA with amphetamine was detected in a round orange pill in Innsbruck. In Slovenia, a Donkey Kong pill contained NEP mixed with an unknown compound, following recent detections in other countries across the region.
Cathinone diversity
As reported in previous weeks, 4-MMC is becoming increasingly rare while numerous substitutes remain in circulation.
Samples contained 3-CMC, 4-CMC, 2-MMC, 3-MMC, 4-BMC and NEP. Ethylpentedron was also detected this week.
