Received my can yesterday (Monday, 3/18) and got a pack in about 30 minutes before hitting the gym.
Since it was my first day with the new Stak, here are my initial thoughts:
-The new formula seems smoother without the caffeine pills. I usually threw them away anyway and just took a shot of Rage.
-Fatigue didn't set in where it normally does in my session. I hit all of my reps/sets, hit a new PR on Standing Overhead Press, and was still fired up even after 8 hours in a cube.
-Recovery this morning was better than usual. My muscles are sore; but nowhere near their normal level.
