MPT (N-Methyl-N-propyltryptamine)
Also known as N-Methyl-N-propyltryptamine · Methylpropyltryptamine
MPT is the N-methyl-N-propyl homolog of DMT, an obscure psychedelic tryptamine. It has appeared only rarely as a research chemical and lacks any formal human study; all descriptions are anecdotal.
01 Overview
MPT (methylpropyltryptamine) belongs to the family of asymmetrically substituted DMT analogs. Its properties are inferred largely from its position between DMT and DPT in the structural series.
No controlled pharmacology, safety or pharmacokinetic data exist. All dose and effect information below is anecdotal and should be regarded as unreliable.
