4-ACO-DMT

4-Acetoxy-N, N-dimethyltryptamine (also known as 4-AcO-DMT, 4-Acetoxy-DMT, O-Acetylpsilocin, and psilocin) is a novel psychedelic substance of the tryptamine class. It is chemically similar to psilocybin, the active ingredient in psilocybin mushrooms (magic mushrooms). It belongs to a group known as the substituted tryptamines which act by stimulating serotonin receptors in the brain.

The synthesis of 4-AcO-DMT was first reported in 1963 by Albert Hofmann and Franz Troxler
