Subtle but Effective: Six Months of Semi-Regular Use
This is going to be a long report, so if you want to get straight to the effects of the drug, just skip to the ďEFFECTS & DOSAGEĒ section. 4-fluoro-methylphenidate will be referred to as 4F-MPH.
Since my youth, Iíve been a firm believer in the idea of better living through chemistry. Iíve tried several dozen different drugs, but Iíll skip the tradition of giving a complete list of every drug Iíve tried. But, since this is a report on a stimulant, Iíll list the stimulants Iíve tried: amphetamine (both dextroamphetamine and Adderall), methylphenidate, ephedrine, dexmethylphenidate, ethylphenidate, isopropylphenidate, cocaine, n-ethylhexedrone, 2-FMA, lisdexamfetamine, and of course caffeine and nicotine. Suffice it to say Iím experienced. I primarily use these drugs - some of which were/are prescribed - to treat adult ADHD.
My daily experience is a struggle to function. Although my ADHD isnít severe, I have an extremely demanding and busy life. Without stimulants, I am constantly forgetting meetings, missing deadlines, and generally failing to keep up with my life. Simple things, like listening to people talk longer than a few minutes, are a monumental challenge. My mind inevitably drifts toward other things. Since Iím so busy, itís hard to pay attention to anything for very long without thinking about the plethora of other things I have to deal with.
I have non-drug ways to cope with ADHD, like intense daily exercise, getting plenty of sleep, and taking carefully scheduled breaks. I am a zealous listmaker, and I use lists with an almost religious fervor. Even writing this report was put on my list - otherwise it would have never gotten done. Regardless, without a chemical stimulant, Iím simply not as functional as I need to be.
4F-MPH appealed to me for two reasons. First, its duration is perfect for a workday. One dose in the morning, with a smaller booster dose in the afternoon, is enough to last me well into the early evening. Second, itís very potent - supposedly 3.33 times as potent as methylphenidate - meaning I get more bang for my buck.
I ordered the drug from a research chemical vendor on the dark net, and before long I was anxiously opening the package. A reagent test indicated that it was, most likely, the substance in question. I prepared a volumetric solution, and the next morning I put 7 mg in a water bottle and went to work.
EFFECTS & DOSAGE
4F-MPH takes up to an hour to kick in orally. For functional purposes, there is no reason to take more than 10 mg at once unless you have a strong tolerance. While many people take 15+ mg, thatís definitely a recreational dose. For me, a perfect functional dose is 3 mg. That may not seem like much, but other people have confirmed the potency of this compound. Anyone without a stimulant tolerance should be able to feel 5 mg or less. To be fair, Iíve always preferred subtle stimulation and believe in the ďless is moreĒ philosophy, but 3 mg always does the job for me.

My initial 7 mg dosage, which was followed by an additional 6 mg later in the day, resulted in a harsh comedown. It went something like this:
T + 0:00 After some sipping, I polish off the water bottle with the dose in it.
T + 0:35 I arrive at work, not feeling much. I begin to think I havenít taken enough.
T + 0:50 Unusually chatty, somewhat distracted.
T + 1:00 I am slammed with stimulation and focus. I begin working rapidly, but due to a lack of work to do I quickly become bored and begin reading a million articles online.
T + 2:30 Simultaneously focused and distracted, I find a quiet spot in the office and get some more work done.
T + 4:00 Past the peak, I eat lunch and take an additional 6 mg.
T + 4:45 Now more stimulated than at any point in the day. Iíve taken too much.
T + 6:00 Heart pounding, sweating profusely, and highly anxious, I retreat to the bathroom. I stay there for twenty minutes, compulsively checking my phone. People notice my strange behavior.
T + 8:00 The rest of the day having been rather lazy and unproductive, I go home. By the time I arrive back home, I feel better, but fried. I read a bit, eat dinner (I had no appetite for it and had to force myself to eat). I am irritable and unpleasant for the rest of the evening, and eventually go to bed where I have trouble sleeping.
I eventually lowered the dose, which was helpful, and rarely take more than 5-6 mg in a day. At this dose, the effects are a subtle stimulation, mood boost and somewhat increased focus. Motivation is a little better but generally unchanged. Compared to methylphenidate, itís a little less physically stimulating but as good or better at treating my ADHD.
4F-MPH typically lasts 4-6 hours, with residual stimulation lingering for an hour or two after. There is some euphoria/mood boost, but it only lasts for the first hour or two. I take it 2-4 times per week to avoid tolerance, with caffeine.

I also notice it makes me much more chatty, but I donít know if this is an empathogenic effect or just increased energy.
As far as the -phenidates go, this one is a good treatment for my ADHD. Getting the dosage right is tricky, and definitely requires volumetric dosing, but once I figured that out this drug has immense potential. Iím a big fan. Its duration and effects are perfect for my life.
The comedown is rarely of the ďI want to fucking dieĒ variety at reasonable doses, unlike cocaine or cathinones. Instead, itís characterized by fatigue, inattention, mild irritability and insomnia (donít take it within 8-10 hours of trying to sleep). Coming down on this drug feels like having all the spark sucked out of my brain. Really, I just feel foggy and tired. Itís not terrible, but it isnít fun.
Notably, the comedowns get worse and the positive effects get less prominent with daily use. I canít use this more than two days in a row, or else Iíll be totally useless and my ADHD will become much worse. Taking too much makes me feel like a zombie, so be careful.
Over the last six months, I have been using this pro re nata with good effect. I haven't noticed any negative physical or mental health consequences, and use no other drugs regularly besides caffeine.
For me, this is the perfect ADHD medicine. I wish it could be prescribed by a doctor, but alas, the nature of drug laws would never allow it. Good luck, and stay safe.
