2-PA is an extremely obscure beta-keto phenethylamine with almost no documented human use. TripSit describes it as amphetamine with the alpha-methyl replaced by a ketone. Human data are limited to a handful of online self-experiments; no formal pharmacology, toxicology, or safety studies exist. Assume cathinone-like risks including cardiotoxicity, neurotoxicity, tachycardia, vasoconstriction, and hyperthermia. Always perform an allergy test (≤5 mg), use an accurate milligram scale, avoid consecutive-day use, and stay hydrated.
