4-Methyl-AMT

4-Methyl-αMT (MP-809), also known as 4,α-dimethyltryptamine (4,α-DMT), is a drug belonging to the tryptamine class that was investigated as an antidepressant in the early 1960s but was never marketed. It was briefly mentioned in TiHKAL by Alexander Shulgin as a psychedelic, with oral doses of 20 mg producing "feelings of unreality" in human subjects, as well as peripheral side effects such as flushing, muscle tightness, and mydriasis.
