So, I was looking over the ModUP store website (https://www.modup.net/shop/) and I noticed that they sell a lot more than just modafinil and armodafinil. Included on their product list are racetams, such as piracetam, aniracetam, oxiracetam, pramiracetam, and phenylpiracetam. I read here that piracetam is one of the oldest and most widely used smart drugs because of its ability to "disable the enzyme of a neurotransmitter called acetylcholine." I know that acetylcholine is responsible for cognitive functions such as memory and focus, so I wonder if taking piracetam in addition to modafinil and/or on my modafinil 'off days' would increase these functions? Let me know if you have had any experiences with the other nootropics on ModUP's store, specifically the racetams, and if so, whether you would recommend them. Thanks!
