4F-MPH is sold in 15mg Pellets.
Formally know as 4-Fluoromethylphenidate, 4F-MPH is a synthetic stimulant in the classes of substituted phenethylamine and piperidine. 4F-MPH produces long-lasting euphoriant and stimulating effects. It is a closely related structural analog of the commonly prescribed ADHD drug methylphenidate (which is known by the brand-names Ritalin and Concerta).
ADHD & 4F-MPH 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. Research reports suggest that it is considerably more potent, with fewer uncomfortable side effects, such as anxiety and muscle spasms. This perhaps owes to the fact that it has been shown to act as a higher efficiency dopamine reuptake inhibitor, than its parent compound Methylphenidate.
