n-methyl-n-propyltryptamine (abbreviated mpt; also known as methylpropyltryptamine) is a synthetic psychedelic of the tryptamine class that has reported to display powerful hallucinogenic and sometimes entactogenic effects. it is structurally analogous to n,n-dimethyltryptamine (dmt) and various base psychedelic tryptamines by which one can have a “breakthrough” experience such as met, ept, and dpt.
while little is known aboout the pharmacology of this substance, early reports indicate it shares that vaporizing or freebasing the compounds shares most of the core components of the dmt experience, just with its own stylistic pharmacodynamic and kinetic variations.
mpt is extremely uncommon and has little history of human usage. it has never been documented as being sold on the street and is instead primarily acquired through the use of research chemical vendors and outfits who specialize in the sale of exotic psychoactive chemicals.
due to the lack of research regarding the substance, all discussion regarding the pharmacology of it is purely based on its structure and subjective effect similarities to other tryptamine psychedelics such as psilocin and dmt. with this in mind, mpt is thought to act as an 5-ht2a partial agonist.
however, the role of these interactions and how they result in the psychedelic experience continues to remain elusive.
