Sure, you can try miscellaneous drugs. I have nothing against that in principle, but most people aren't aware of the "basics". It seems wise to handle those first. But what are the "basics" anyway?
1. Take a B vitamin supplement with plenty of thiamine. When you want to be at the top of your game, have a bag of thiamine HCL powder ready and take 1 gram with food. Yes, 1 whole gram.
2. Consider supplementing T3, the active thyroid hormone. Your brain needs this at a basic biological level to function efficiently. For some people, the difference is night and day.
3. A small dose of methylene blue is safe and well tolerated.

>About thirty years ago, someone found that the speed with which the iris contracts in response to a flash of light corresponds very closely to the I.Q. measured by a psychologist using a standard intelligence test. The devices used to measure reaction time in drivers' education courses also give a good indication of a person's intelligence, but so does measuring their heart rate, or taking their temperature. Colleges would probably be embarrassed to admit students on the basis of their temperature (though they commonly award scholarships on the basis of the ability to throw a ball). Colleges, to the extent that they are serious about the business of education, are interested in the student's ability to master the culture.
>Any chemical support for intelligence should take into account the mind-damaging stresses that our culture can impose, and provide defense against those. In darkness and isolation, for example, the stress hormones increase, and the brain-protective steroids decrease. The memory improvement that results from taking pregnenolone or thyroid (which is needed for synthesizing pregnenolone from cholesterol) is the result of turning off the dulling and brain-dissolving stress hormones, allowing normal responsiveness to be restored.
