Piracetam with Focus XT works well for me. I've using half a scoop of Focus XT and 2 grams of Piractem over the last couple of weeks and I've noticed my cognition has improved. I'm able to capture and process concepts quicker and with less effort. Aniracetam was less consistent for me - sometimes my verbal fluency would increase and I would be on point speaking to people. Other times it would leave me a little dazed - but when it worked it was impressive.
