4-Acetoxy-MET (4-Acetoxy-N-methyl-N-ethyltryptamine), also known as metacetin or 4-AcO-MET, is a hallucinogenic tryptamine. It is the acetate ester of 4-HO-MET, and a homologue of 4-AcO-DMT. It is a novel compound with very little history of human use. It is sometimes sold as a research chemical by online retailers.
It is expected that the compound is quickly hydrolyzed into the free phenolic 4-HO-MET by serum esterases, but human studies concerning the metabolic fate of this drug are lacking. There is proof that this is a very active substance.
4-Acetoxy-MET is unscheduled in the United States.
