Nootropics and performance

[Fastandfurious]

Has anyone using nootropics (piracetam,aniracetam etc and other smart drug-type drugs-not amphetamines or stimulants like ephedrine) seen actual performance gains from them ? Like more weight lifted,more reps ,more work capacity or better CNS recuperation ? Or anything directly or indirectly linked to better performance ?
Or is their effect strictly in the mind -only making you feel more focused or aware ?

I use the BJ stack of pram/pir/cho/gp3 and for sure see more concentration and can stay focused for longer, no direct link for performance that I could actually say was noticable.
