Oh yah, he didn't learn, this is his 3rd ticket this month. He should've listened to me when I told him to go on the 70 mph Diet.

4F-MPH is 4-Fluoromethylphenidate (Fluoritalin). It releases a little more Norepinephrine than Ritalin (Methylphenidate, MPH), and like at least triple the amount of Dopamine as Ritalin (Methylphenidate, MPH). 4F-MPH dose range is 5mg to 15mg+ and it lasts around 3 to 6 hours.

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.
