Halogenated amphetamines are generally neurotoxic indeed, but fluorine is a bit different as a chemical moiety than the other ones: for example it is quite quite small. Of course still very electronegative but the steric hindrance should be much less. From what we know it seems the fluorinated ones aren't really that toxic but I understand if people would just rather stay away altogether. Definitely stay away from stuff like brephedrone (bromo-mephedrone... probably quite harmful, yet it is available)
2-FA resembles dexamphetamine most of the fluoramphs in my opinion. 3 and 4 are exceedingly more serotonergic and effective for other purposes than studying. Forget about the (meth)cathinone and methamphetamine varieties, they are probably more harmful and also more meant for recreation.
PEAs with deprenyl is a quite dangerous plan and I would always recommend against such things. I have tried beta-PEA on it's own and it gave a very warm and sweet feeling but it was extremely fleeting, went away in not more than a few minutes. So gave up on that. Didn't even improve attention, only lovey-dovey stuff.
Desoxypipradrol always seemed like an interesting one on paper and I still have it lying around, have it for years now I think. But it can easily spiral out of control with that one. Very tricky shit if you cross the line with it. And sleep is virtually impossible for a good time afterwards, probably the entire following night. If you take a little more than necessary and add a little extra to get that nice little boost-y feeling, then possibly the next thing you know is that you can't sleep for multiple nights and get into an amphetamine-psychosis like state pretty damn fast. Which is why I still dare not touch it with a 10 ft pole.
Ethylphenidate felt alright to me, maybe a little more useful than methylphenidate.
My advice is: modafinil.And potentially in the future (I have yet to try it): other racetams than the piracetam I have yet used extensively (such as
aniracetam) and
Noopept. I have no use for studying myself but to make cartoon work and to put some hours into music production, who knows how useful they can be. And - including modafinil - relatively much safer than the truly monoamine releasing or reuptake inhibiting stims.
Onto the next generation of drugs!
(I think there was another ampakine peptide available on Russian prescription but alas I forgot the name!)
