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.
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.
