most effective nootropics

Hi,
I have used Piracetam and Hydergine nootropicboost.com I currently use Aniracetam and Phosphatidyl Serine/Bacopin. I found that Hydergine was very effective at keeping my alertness level high. I used it primarily to be effective during long meetings. I was able to convince my doctor to prescribe it, therby cutting my costs:) The rest of the suppliments I call the 5% solution, good but not too noticable.
