2-FA
2-FA is a synthetic stimulant of the substituted amphetamine class, distinguished by a fluorine atom at the 2-position of the amphetamine structure. It first emerged on the online research chemical market in the 2010s as part of a series of fluorinated amphetamine analogs. Among these, 2-FA is regarded as the most closely resembling conventional amphetamine in its subjective effects and is frequently compared to dextroamphetamine. It is considered habit-forming.
