TMA-2, known more formally as 2,4,5-trimethoxy-amphetamine, is a psychedelic hallucinogen which has appeared on the illicit drug market. Unlike amphetamines and cathinones, TMA-2 has no effect on monoamine re-uptake. TMA has modest effects on the 5-HT2 serotonin receptors (pEC50 values of 5.15 and 5.31 M for phosphatidylinositol release through 5-HT2A and 5HT2C, respectively). This product is intended for research and forensic applications.
