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]
