4f-mph powder

4-Fluoromethylphenidate (commonly known as 4F-MPH) 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 4F-MPH 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 4f-mph 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.

Cognitive effects

• Many users of this compound report positive, functional cognitive effects associated with the therapeutic aspect of traditional stimulants. This may owe to its similarities to methylphenidate, in which these effects have been well-studied.
  • Anxiety – 4F-MPH anxiety is stronger and more common than that of other commonly used stimulants like amphetamine or cocaine. Similar to the closely related compound. 4F-MPH has a very short-lived and compulsive euphoric rush similar to that of cocaine. This is as result of dopamine reuptake inhibition. Although methamphetamine produce  less reliable and intense rush.
  • Compulsive redosing -users report this but with less frequency than other common stimulants such as amphetamine or cocaine. However, users report it to be more common than the closely related compound methylphenidate at high or non-orally administered doses. Thus, researchers recommend to dose orally or set a limit to avoid using more than needed.
  • Ego inflation
  • Emotion suppression – users reported this component as being more prominent than with other stimulants. However, users say it is in-line with emotion-suppressing effects they observed with other stimulants.
  • Focus enhancement – This component is most effective at low to moderate dosages as anything higher will usually impair concentration.
  • Increased music appreciation
  • Time distortion
  • Motivation enhancement
  • Memory enhancement
  • Suggestibility suppression
  • Thought acceleration
  • Wakefulness
