3-FPM is a derivative of phenmetrazine- a once-popular stimulant substance that was clinically used as an anorectic in Europe in the 1950s. It produces its activity by increasing the levels of serotonin, dopamine, and norepinephrine. 3-Fluorophenmetrazine (3-FPM) is a synthetic molecule of the amphetamine family. Scientists report that 3-FPM had similar classical stimulant outcomes comparable to those of amphetamine. 3-FPM was introduced onto the research chemical market in around 2014, since that time it has become increasingly popular.
