Great little pre here. I took it with a pump formula and had a killer workout, energy was on full blast though not of the heart pounding variety, though I did keep my heart rate up. Went from heavy work sets to accessories and was flying through for a good 2 hrs. Focus was there but didn’t get much in the way of the floaty euphoria. Overall it’s good if not great. They released this again without the DMAA so scoop up the full strength at Muscle Players while they still have it
