What is 4-HO-MET?

4-Hydroxy-N-methyl-N-ethyltryptamine, or 4-HO-MET, is a novel psychedelic substance of the Tryptamine class.

4-HO-MET is chemically related to psilocin, the active ingredient in psilocybin mushrooms (“magic mushrooms”). It was first synthesized by Alexander Shulgin, who documented it in his 1997 book “TiHKAL” (“Tryptamines I Have Known and Loved”).Buy 4-HO-MET Fumarate Online
