What is 4-HO-McPT Fumarate?

4-HO-McPT Fumarate is a rare and modern psychedelic tryptamine belonging to the 4-hydroxy-substituted derivatives. The “McPT” structure refers to an N-methyl-N-cyclopropyltryptamine , making the molecule unique within the serotonergic family due to its compact and rigid side group (cyclopropyl).

Due to its similarity to natural compounds such as psilocin, 4-HO-McPT offers an intriguing research target for pharmacological, receptor analytical, and structural-activity studies.
