4-FA and 4-FMA both come up in the same conversations; they overlap on Dopamine and Norepinephrine. 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. 4-FMA: 4-FMA is methamphetamine with a fluorine at the para (4) position of the ring.
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.
4-FMA is methamphetamine with a fluorine at the para (4) position of the ring. Like other fluorinated methamphetamines it raises dopamine and norepinephrine, with some serotonin activity from the para substitution. It is a poorly studied research chemical and carries the usual amphetamine-class risks plus the caution warranted by para-fluoro compounds.
both fingerprints on one instrument; where the marks line up the two compounds work the same lever, where a slot goes dark only one of them touches it. read straight from each entry's affinity table; nothing here is invented.
