Substances
4F-MPH

A novel synthetic stimulant of the phenidate class. It is a closely related structural analog of the commonly prescribed ADHD drug methylphenidate. The two substances are believed to have very similar pharmacological mechanisms as monoamine reuptake inhibitors but have been reported to display distinctive subjective effects, with 4F-MPH being considered significantly more euphoric and recreational.
