5-Fluoro-α-methyltryptamine (5-Fluoro-αMT, 5F-AMT), also known as PAL-544,[1] is a putative stimulant, entactogen, and psychedelic tryptamine derivative related to α-methyltryptamine (αMT). It has been found to act as a well-balanced serotonin-norepinephrine-dopamine releasing agent,[1] a 5-HT2A receptor agonist,[2] and a potent and specific MAO-A inhibitor.[3][4][5][6] which suggests that 5-fluoro-αMT could be an active psychedelic in humans, although it is not known to have been tested in humans and could be dangerous due to its strong inhibition of MAO-A.
