A lesser-known psychedelic drug is 4-MeO-MiPT, or 4-methoxy-N-methyl-N-isopropyltryptamine. It is MiPT’s 4-methoxy analog. Alexander Shulgin’s 4-MeO-MiPT was first synthesized and is described in his book TiHKAL (Tryptamines I Have Known And Loved). Subsequent tests by Shulgin on human subjects revealed an effective dosage of 20-30 mg (or 0.4 mg per Kg of subject body weight); the time of onset between ingestion and the first measurable effects was 45-60 min, with sensations lasting from 2-2.5 hours. The sensation was significantly milder than that of 4-HO-MiPT, with erotic-enhancing effects produced by 4-MeO-MiPT and few of the visuals typical with tryptamines. There is very little evidence on 4-MeO-pharmacological MiPT’s properties, metabolism, and toxicity.
