Buy 4-HO-MALT 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 psychedelic structure-activity relationships in the 4-substituted tryptamine family.
What is 4-HO-MALT?
4-HO-MALT (4-Hydroxy-N-methyl-N-allyltryptamine), also known as Maltocin, is a synthetic psychedelic of the tryptamine class. It is structurally related to other 4-hydroxy tryptamines like 4-HO-MiPT and 4-HO-MPT, featuring an N-methyl-N-allyl side chain. It first appeared on the research chemical market around 2020 and is sold strictly for laboratory and research purposes only.
