This product has been in my gym bag since the first day I found it. 200% better tasting than some other brands I've tried. The energy levels are good and I haven't found myself to get immune to it's effects as fast as some other products i've tried. I mix in a scoop of straight arg to get the full effects of the product. As far as a solid pump and vascularity i have seen better results with NOXPLODE but not enough to pay double for the same amount of servings and worse taste. Also i've seen no bloat with the Pump Fixx creatine as i had in the past with creatine 'matrix' additions other products have. solid product - highly recommend
