For cognition enhancement, AD makes a great base for a good neuro stack IMO. Do yourself a favor and try it with Citicoline and Huperzine A. Good stuff. Mental clarity and cognition through the roof with 250mg CDP and 100mcg Huperzine. I would assume other products in this category could work just as well. I have some aniracetame that will eventually get incorporated but seeing as how it's my first time using Anirace, a solo run is warranted first.
