4F-EPH (4′-fluoro-ethylphenidate) or 4F-ethylphenidate has substituted phenethylamine, piperidine, and close analog of ethylphenidate and therefore methylphenidate (ritalin).
There has not been many reports on the use of 4F-EPH in humans however due to 4F-EPH and 4F-MPH’s similarities in their pharmacological mechanisms but distinctively different subjective effects where one maybe more euphoric and recreational in its experience while others maybe more functional stimulants.
4F-EPH has little to no history of human usage prior to its distribution online through research chemical vendors.
It was initially developed as a replacement for ethylphenidate which became illegal in the United Kingdom, due to a temporary blanket ban.
