Nootropic for Better Mind-Muscle Connection?

Does anyone have reclendations to improve the mmc? Ive heard of a supplement but the post was deleted so i cant remember! Id really appreciate feedback and to hear your thoughts.
I want to try one or two

I have read Phenylpiracetam is a good one, s9 good it was banned from professional competitions. Any reviews?

L-tyrosine combined with caffeine 15-20 minutes before training is a tried and tested method. Personally just an old fashioned cup of black coffee does the trick for me.

Indeed Caffeine will help you out.
