4F-MPH

Methyl (2R)-2-(4-fluorophenyl)-2-[(2R)-piperidin-2-yl]acetate, known as 4F-MPH, is a synthetic stimulant primarily acting as a dopamine and norepinephrine reuptake inhibitor. It belongs to the class of piperidine derivatives and exhibits effects similar to other methylphenidate analogs, potentially leading to increased alertness and euphoria, but also carries risks such as dependence and cardiovascular adverse effects. Research on long-term effects is limited.
