@heavyhitter if your CNS is anything like your stomach, which is very similar to mine, the racetam family will feel speedy (not to discount their effectiveness) as I have tried and enjoyed a few but I also have hypertension this should be NOTED. Noopept 30-45 min before desired time of study, I dont remember what I Used to use to potentiate it but there was something I used. Taurine and Noopept saved my body and mind when I was abusing substances. I want to say noopept has some beneficial effect on our nMDA receptors if I remember correctly which is good for ptsd sufferers. Eggyolks have choline in them
