An hour after taking phenylpiracetam I noticed it kick in and I felt a subtle sensitivity and awakening. An hour afterwards I had a 8oz red bull and my alertness became much much sharper, far sharper had I just had the phenylpiracetam or red bull.
It's a very interesting alertness, much smoother feeling than having a lot of caffeine.
Has anyone else experienced something similar? Does Phenylpiracetam increase\potentiate other substances?
Thanks!
