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.
Dosage and duration
For psychedelic effects, the dosage and duration are listed as "unknown" in TiHKAL.
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.
4-HO-MPT is not scheduled at the federal level in the United States, 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.
