This is my #1 pre workout. I have at least ten different pre workouts in my cabinet. I have noticed some of them vary from day to day depending on diet and other vitamins. DUST always remains the same and can be counted on. Give a really nice focused energy that allows me to push the limits. On arm days, stack this with Blackstone's HYPE. The only down fall I have with DUST is every flavor (which I have them all) has this kind of odd synthetic ting. Given the results it produces, it is certainly worth it.
