What is 4-AcO-MPT Fumarate?

4-AcO-MPT is a psychedelic tryptamine and an ester form of 4-HO-MPT. It is structurally related to both psilocin (4-HO-DMT) and other 4-substituted tryptamines, and is being investigated for its potential agonistic effect on 5-HT2A receptorsIf fumarate salt it is more suitable for laboratory applications than the free base, due to higher stability and solubility.
