4-HO-MPT (4-Hydroxy-N-methyl-N-propyltryptamine or Meprocin) is a novel synthetic psychedelic substance of the tryptamine chemical class that produces psychedelic effects. It is a closely related structural analog of 4-HO-DMT (Psilocin) and other hallucinogenic tryptamines with powerful psychedelic effects.
Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-HO-MPT, so look after your research subjects.
