4-Hydroxy-N-methyl-N-propyltryptamine, commonly known as 4-HO-MPT or meprocin, is a psychedelic drug in the tryptamine class of chemical compounds and is a higher homologue of the naturally occurring substituted tryptamine psilocin as well as being the 4-hydroxyl analog of MPT.

History

4-HO-MPT was first synthesized and bioassayed by biochemist Alexander Shulgin and written about in his 1994 book TiHKAL.^[1]

Dosage and duration

For psychedelic effects, the dosage and duration are listed as "unknown" in TiHKAL.^[1]

Effects

Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-HO-MPT. In a single trial of 8 mg orally of 4-HO-MPT HCl from TiHKAL, it is described as producing visual distortion, vertigo, and slight insomnia.^[1]

Legal status

4-HO-MPT is not scheduled by the United Nations' Convention on Psychotropic Substances.^[2]

United States

4-HO-MPT is not scheduled at the federal level in the United States,^[3] but it is possible that 4-HO-MPT could legally be considered an analog of psilocin, in which case, sales or possession with intent for human consumption could potentially be prosecuted under the Federal Analogue Act.^[4]
