I like what it does for my workouts
This is the first and only pre workout I've tried. I like what it does for my workouts. Seems to help me lift heavier, go longer, and as an added benefit it makes my muscles look huge post workout. Non of the jittery feelings I've heard other people describe with caffeinated pre workouts.  I will say that for the first week and a half of using it, after my workout I felt kind of nauseous until I ate something. I don't like to eat before I workout (in the morning) and I think taking this on an empty stomach is what caused the nausea. After using it regularly for about 2 weeks, that went away.
