4-Fluoromethylphenidate (commonly known as 4F-MPH) is a novel synthetic stimulant of the substituted phenethylamine and piperidine classes that produces long-lasting euphoriant, and stimulating effects associated with monoamine reuptake inhibitors when adminstered.4f-mph source,4f-mph powder,legal,usa vendor
It is a closely related structural analog of the commonly prescribed ADHD drug methylphenidate (known by the brand-names Ritalin and Focalin).
The two substances are believed to have very similar pharmacological mechanisms but have been reported to display distinctive subjective effects, with 4F-MPH being considered significantly more euphoric and recreational.
Anecdotal reports suggest that it is considerably more potent with fewer uncomfortable side effects such as anxiety, muscle spasms and compulsive.4f-mph source,powder,legal,usa vendor
This perhaps owes to the fact that it has been shown to act as a higher efficiency dopamine re uptake inhibitor than the parent compound methylphenidate.ALD-52
4F-MPH has an extremely short history of recreational use and has yet to be documented being sold on the streets. It was initially developed as a replacement for ethylphenidate which became illegal in the United Kingdom on April 2015 following a temporary blanket ban. Shortly after, it recently became made available for sale on the online gray market as a research chemical for global distribution.
Due to its potent, long-lasting stimulant effect, likely habit-forming properties as well as unknown toxicity profile, it is strongly recommended that one use proper harm reduction practices if choosing to use this substance.
