4-HO-MET
4-HO-MET is a synthetic psychedelic tryptamine first synthesized by Alexander Shulgin and documented in his 1997 book TiHKAL. Structurally related to psilocin, it produces effects through serotonin receptor agonism. Users typically describe it as more recreational than psilocybin mushrooms, characterized by vivid colorful visuals with a less mentally intense headspace. Reports of human use emerged in the late 2000s following its appearance on the research chemical market. Very little data exists regarding its toxicity profile.
