4-Hydroxy-N-methyl-N-isopropyltryptamine (also known as 4-HO-MiPT, and Miprocin) is a novel psychedelic substance of the tryptamine class. It produces psilocybin-like psychedelic effects when administered. It is part of a series of psychedelic substituted tryptamines such as 4-AcO-DMT, 4-HO-MET, 4-HO-DiPT. They are considered to produce variations of the core psychedelic effects typified by psilocin.
This substance is relatively uncommon and has only a short history of human use. Alexander Shulgin evaluated its activity in humans in 1979, describing a trial of 12mg as a richly insightful and highly erotic experience. A description of 4-HO-MiPT is included in Shulgin’s 1997 book TiHKAL. Shulgin’s trials and other anecdotal reports suggest that 4-HO-MiPT is similar in activity to psilocin. Thus, the active component in psilocybin mushrooms. 4-HO-MiPT Pellets
Very little data exists about the pharmacological properties, metabolism, and toxicity of 4-HO-MiPT in humans. As with psilocin, there have been no reported deaths from 4-HO-MiPT use despite the existence of reports of people taking doses which far exceeds the active dose. This suggests that it is well-tolerated physiologically.
Today, 4-HO-MiPT is either used recreationally or as an entheogenic substance and is typically distributed as a grey-area research chemical by online vendors. 4-HO-MiPT Pellets
