6-Fluoro-AMT, or 6-fluoro-αMT, also known as 6-fluoro-α-methyltryptamine, is a psychedelic drug of the tryptamine family related to α-methyltryptamine (AMT) and 5-MeO-AMT.[1][2]

Use and effects

[edit]

6-Fluoro-AMT was allegedly manufactured and sold from the laboratory operated by Leonard Pickard and Gordon Todd Skinner, who described 6-fluoro-AMT as "a beast".[1] In interviews, Skinner stated that he first began to experiment with 6-fluoro-AMT in the early 1980s by giving it to high school friends.[2] Their experiences made him cautious about the appropriate doses, which he said ranged from 25 to 75 mg (Skinner weighed about 250 lbs at the time of his own bioassay).[2] Skinner said that 6-fluoro-AMT is a long-lasting psychedelic with more time distortion and that it was enhanced by combination with ALD-52.[2]

Pharmacology

[edit]

Pharmacodynamics

[edit]

Animal tests showed the drug to be somewhat less potent in terms of pharmacological activity than AMT or 5-fluoro-AMT.[3] It produces the head-twitch response, a behavioral proxy of psychedelic-like effects, in rodents.[5] Its IC50Tooltip half-maximal inhibitory concentration for monoamine oxidase A (MAO-A) inhibition is 580 to 1,800 nM, compared to 180 to 450 nM for 5-fluoro-AMT and 380 nM for AMT.[5][7][8]

Analogues

[edit]

Analogues of 6-fluoro-AMT include α-methyltryptamine (AMT), 5-fluoro-AMT, 5-chloro-AMT, 5-fluoro-AET, 5-chloro-AET, 6-fluoro-DMT, 6-fluoro-DET, 6-methyl-DMT, 6-MeO-DMT, 6-hydroxy-DMT, 7-chloro-AMT, and O-4310 (1-isopropyl-6-fluoro-4-HO-DMT), among others.

History

[edit]

6-Fluoro-AMT was first described in the scientific literature, by Asher Kalir and Stephen Szara, by at least 1963.[3]

Society and culture

[edit]
[edit]

6-Fluoro-AMT is not an explicitly nor implicitly controlled substance in Canada as of 2025.[9]

United States

[edit]

6-Fluoro-AMT is not an explicitly controlled substance in the United States.[10] However, it could be considered a controlled substance under the Federal Analogue Act if intended for human consumption.
