4-AcO-DET

4-AcO-DET is a synthetic psychedelic of the tryptamine class, first synthesized by Albert Hofmann at the Sandoz laboratory in 1958. It is chemically related to psilocin and belongs to a series of substituted tryptamines that includes 4-AcO-MET and 4-AcO-DMT. Its effects are generally compared to those of psilocybin mushrooms. It remains a lesser-known research chemical, typically encountered as a slightly off-white powder and most commonly administered orally.
