Fantastic product. Blue Raz is perfect, just the right amount of sweet flavor for me. The caffeine free aspect is great, no jitters, all pump. Definite performance increase getting a couple more reps at the end of a good set and tight full muscle pumps. I look jacked after a good workout and Pump Mode. If you do want a bit of extra energy consider stacking with BCAA Energy to kick your workout up a notch. EVL is a definite go to supp co for me. Go Hard Go Heavy and do One More Rep.
