2-FMA and 4-FA both come up in the same conversations; they overlap on Dopamine and Norepinephrine. 2-FMA: 2-FMA is methamphetamine with a fluorine added at the ortho (2) position of the ring. 4-FA: 4-FA is amphetamine with a fluorine at the para (4) position of the ring, which shifts its character toward a hybrid of stimulant and mild entactogen.
2-FMA is methamphetamine with a fluorine added at the ortho (2) position of the ring. It works on the same dopamine and norepinephrine machinery as its parent, but people tend to describe it as more subtle and functional than euphoric. It still carries the usual stimulant load on the heart, sleep, and appetite.
4-FA is amphetamine with a fluorine at the para (4) position of the ring, which shifts its character toward a hybrid of stimulant and mild entactogen. It releases dopamine, norepinephrine, and a meaningful amount of serotonin, so people describe an amphetamine-like push with some MDMA-like warmth. It is notable for a real, documented risk of sudden cardiovascular events, so it deserves particular caution.
