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.

Some of the most commonly reported effects are:

  • Stimulation
  • Anxiety suppression
  • Disinhibition
  • Empathy, affection, and sociability enhancement
  • Analysis enhancement
  • Conceptual thinking
  • Emotion enhancement
  • Cognitive euphoria
  • Immersion enhancement
  • Increased music appreciation
  • Memory suppression
  • Ego death
  • Thought acceleration
  • Thought connectivity
  • Time distortion
  • Wakefulness
  • Acuity enhancement
  • Colour enhancement
  • Pattern recognition enhancement
