I got this pre in the blue slush flavor and not only did it taste great, it delivered the most insane energy, pump, and focus I've ever felt from a pre. My caffeine tolerance is high, so I took two scoops and it sent me! After I hit legs I still had so much energy that I hit cardio for an hour. This pre is no joke. It's basically motivation in a tub. 10/10 and my new favorite.
