Summary
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.
