4,5-MDO-DMT
4,5-MDO-DMT, or 4,5-methylenedioxy-N,N-dimethyltryptamine, is a lesser-known psychedelic drug of the tryptamine family. It is the 4,5-methylenedioxy derivative of dimethyltryptamine (DMT) and is an analogue of psilocin (4-HO-DMT) and 5-MeO-DMT. The drug was included as an entry in Alexander Shulgin's 1997 book TiHKAL (Tryptamines I Have Known and Loved), but it was not tested to determine its psychoactive effects and its dose and duration are unknown.
