2-FMA
2-FMA is a synthetic stimulant of the substituted amphetamine class, structurally related to methamphetamine through fluorination at the 2-position. Available as a research chemical since approximately 2012, it is frequently compared to lisdexamfetamine (Vyvanse) for its utility as a productivity and study aid. 2-FMA is generally regarded as less euphoric and less recreationally appealing than traditional amphetamines. Little formal research on the substance exists.
