Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.

Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.

Disclaimer: Psychedelic drugs offer some of the most powerful and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

A long-acting psychedelic-empathogen with a broad method of action in the brain. Not suitable for combination with many other substances. Used as an anti-depressant in the Soviet Union, but later found popularity in the RC scene, mainly in the UK.

Summary

αMT was originally developed by Upjohn in the 1960s. It was briefly used in the Soviet Union as an antidepressant under the trade name Indopan. 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. " 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. 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.

Chemistry

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.

Interactions

Caution

  1. Cannabis
    • Cannabis has an unexpectedly strong and somewhat unpredictable synergy with psychedelics. Small amounts can reduce nausea with aMT but take care.
  2. Caffeine
    • High doses of caffeine may cause anxiety which is less manageable when tripping, and since both are stimulating the combination may cause some physical discomfort.
  3. Alcohol
    • aMT has a broad mechanism of action in the brain and so does alcohol so the combination can be unpredictable
