i am in a serious search for any drug or medicine that can give me the highest level of mind concentration the mind can attain.i need everybody to help me.

[MrMistery]

careful sir. some of those drugs can have SEVERE complications and side effects, that include acquiring an addiction, insomnia(because some contain outrageous quantities of cafeine), inability to concentrate and slight dislexia after you stop using them and more.
Whatever you do, don't take anything based on metamphetamine(i am not joking, some derived compounds are used to stimulate concentration and memory by insane college students). That will(not can, will) lead to severe addiction and sometimes even brain damage if you use it for too long
Once more, be careful.
The best option would be to buy supplements that contain B vitamins, lecitine and natural extracts such as Ginkgo biloba, gingseng etc

Concentration is useless without knowledge, knowledge does not come without understanding, understanding does not come without study, and study...well study cannot be done without some serious time investment.

hahaha this is so funny those drugs you're looking for would not help you concentrate but only narrow your consciousness or focus of attention. The pilots that infamously took amphetamines for long flights over Iraq werent very concentrated on what they were doing they were just hypervigilant for anything appearing on the screen...

DRUGS... you probably have to consult your doc here. It's not that easy to give an idea 'bout the drug, specially that drug metabolism really affects our physiology.

there are plenty of drugs for ADD, if such a thing exists.
