Alpha,N,O-TMS

Alpha,N,O-TMS, or α,N-dimethyl-5-methoxytryptamine, is a lesser-known psychedelic drug. Its abbreviated nomenclature is derived from its structure, as it is α,N,O-trimethyl serotonin. α,N,O-TMS was first synthesized by Alexander Shulgin. In his book "TiHKAL" ("Tryptamines I Have Known and Loved"), Shulgin lists the dosage as 10-20 mg when taken orally, and the duration as 6–8 hours.
