4F-MPH

4F-MPH is 4-Fluoromethylphenidate (Fluoritalin). The dose range is 5mg to 15mg+. It's an NDRI (Norepinephrine-Dopamine reuptake inhibitor) that releases Dopamine and Norepinephrine. It helps with ADHD to focus, remember stuff, study, gives a confidence boost, and more. Side effects include anxiety, and a riddle in your mind feeling. It lasts around 3 to 6 hours. It also combines nicely with ethanol (alcohol) to form 4F-EPH.

Tony: I took 15mg of 4F-MPH (4-Fluoromethylphenidate) and was studying for 6 hours straight.
