3f-pihp powder

3f-pihp is a novel synthetic stimulant of the phenidate class that produces long-lasting euphoriant, and stimulating effects when administered. This chemical is closely related structurally to methylphenidate.

Researchers beleive two substances have very similar pharmacological mechanisms as monoamine reuptake inhibitors. However, they display distinctive subjective effects, with 3f-pihp which is 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 redosing. This perhaps owes to the fact that it has been shown to act as a higher efficiency dopamine reuptake inhibitor than the parent compound methylphenidate.

Recreational users of 3f-pihp are few. 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 became available for sale on the online gray market as a research chemical for global distribution.

Due to the potent, long-lasting stimulant effect, likely habit-forming properties as well as unknown toxicity profile. Manufacturers strongly recommend proper harm reduction practices when using this substance.
