4-HO-MiPT (miprocin, 4-hydroxy-N-methyl-N-isopropyltryptamine, hats) is a synthetic substituted aromatic compound and a lesser-known psychedelic tryptamine. It is thought to be a serotonergic psychedelic, similar to magic mushrooms, LSD and mescaline. Its molecular structure and pharmacological effects resemble those of the tryptamine psilocin, which is the primary psychoactive chemical in magic mushrooms.
