Buy 4-HO-MPT fumarate

Buy 4-HO-MPT Fumarate is a high-purity research chemical (available in powder or pellet form). Laboratories and researchers use it to study tryptamine pharmacology, serotonin 5-HT₂A receptor activation, and structure-activity relationships of asymmetrical N-substituted 4-hydroxytryptamines.

What is 4-HO-MPT?

4-HO-MPT (4-Hydroxy-N-methyl-N-propyltryptamine) is a synthetic psychedelic of the tryptamine class. It is the 4-hydroxy derivative featuring an N-methyl-N-propyl side chain. It is structurally related to other 4-substituted tryptamines such as 4-HO-MET and 4-HO-MiPT. It is often studied as the active metabolite of 4-AcO-MPT. Sold strictly for laboratory and research purposes only.
