What Is 4-Pro-MET?
4-Pro-MET — chemically 4-propionoxy-N-methyl-N-ethyltryptamine — is a synthetic tryptamine derivative. The compound serves as a prodrug: in the body, the propionyl ester group is cleaved, producing 4-HO-MET (metocin) — the actual active metabolite.
As of April 2026: 4-Pro-MET is not listed under the BtMG or NpSG in Germany. Legal status may change — always verify the current regulations in your jurisdiction.
