Methylpropyltryptamine (MPT), also known as N-methyl-N-propyltryptamine, is a psychedelic drug of the tryptamine family. It is a homologue of methylethyltryptamine (MET).[1]
Use and effects
In his book TiHKAL (Tryptamines I Have Known and Loved), Alexander Shulgin described MPT’s effects as being unknown and its dose as being greater than 50 mg orally.[1]
Interactions
Chemistry
Detection
An analytical method for MPT’s detection has been reported.[2]
Crystal structure
In 2019, Chadeayne et al. published the crystal structure of MPT.[3] The authors describe the structure as “…a single molecule in the asymmetric unit, with an indole group that demonstrates a mean deviation from planarity of 0.015 A°.”
Analogues
Analogues of MPT include 4-HO-MPT, 5-MeO-MPT, methylethyltryptamine (MET), ethylpropyltryptamine (EPT), ethylisopropyltryptamine (EiPT), and dipropyltryptamine (DPT), among others.[1]
Society and culture
Legal status
Canada
MPT is not a controlled substance in Canada as of 2025.[4]
United States
MPT is not an explicitly controlled substance in the United States.[5] However, it is an isomer of diethyltryptamine (DET), which is a schedule I controlled substance in this country, and so may be considered a controlled substance in the United States similarly.[5][6]
