I have become obsessed with intelligence and IQ, and ways of improving cognitive function. Tried out Nootropics one of the racetams, Huperzine A, Adrafinil prodrug of modafinil, and the other stuff(The best for me is fishoil and vitamin D, add some choline to that too) https://en.wikipedia.org/wiki/Nootropic.

Never tried the study drugs that are usually talked about with neuroenhancement like Modafinil, ADHD medications such as Methyl Phenidate, and dextroamphetamine or those alzheimers medications such as donepezil(acetylcholine esterase inhibitor) and Memantine(NMDA antagonist)
https://en.wikipedia.org/wiki/Neuroenhancement.

Have tried TDCS(Trancranial direct current) bought one for like 100$ tried it out felt like a nice tingling buzz of alertness, nothing special helped a little. Also checked out some of the literature on improving fluid intelligence and was wondering if there was anything more to it.

Now before you reply PLEASE go through the sources and confirm or disprove whatever I've cited about improving intelligence. Here is the sources
