AMT Succinate

What is AMT?
α-Methyltryptamine (also known as Indopan and commonly as αMT or aMT) is a lesser-known entactogen substance of the tryptamine class.[1]
αMT was originally developed by Upjohn in the 1960s.[2] It was briefly used in the Soviet Union as an antidepressant under the trade name Indopan.[1][3][4][5] Indopan was prescribed in 5-10 mg doses, which is significantly lower than the dose used for recreational effects.
Erowid has received “a handful of unverifiable reports of hospitalization after high-dose (over 60 mg oral) αMT ingestion.”[6] There were 22 deaths linked to αMT in England and Wales where the drug became popular as a legal high from 2012 until it was banned in early 2015.[7]
Limited data exists about the pharmacological properties, metabolism, and toxicity of aMT, and it has a limited history of non-medical human use. It is highly advised to use harm reduction practices if using this substance.
Chemical Properties
αMT, or α-Methyltryptamine is a synthetic indole alkaloid molecule of the tryptamine class. Tryptamines share a core structure comprised of a bicyclic indole heterocycle attached at R3 to an amino group via an ethyl side chain. AMT is substituted at the alpha carbon Rα of its tryptamine backbone with a methyl group.
AMT is found in freebase form as a racemate of its (R-) and (S-) enantiomers.
Pharmacological effects
αMT’s psychedelic effects are believed to come from its efficacy at the 5-HT2A receptor as a partial agonist.
αMT also acts as a releasing agent of serotonin, noradrenaline, and dopamine.[8][9] It also acts as a very weak, non-selective RIMA in-vitro[10] and in-vivo.[11], but this is unlikely to be very significant (if at all) with common doses.
