Craze is definitely a solid pre-workout and DAA is clearly a great addition for pre-workout with more aggression. How long has it been since you've had a break from stimulants, OP? I only ask because if you're taking 2 scoops of Craze on a semi-regular basis, I'd be looking to take a good break to let your body relax and let your sensitivity come back. And if you're enjoying the Power Chews as a nice snack, I'd go for the BCAA or glutamine chews so you can munch on them whenever. You can get away with it with D-Test and creatine, but I'd rather take in more BCAAs or glutamine, personally (if we're talking past the minimal amount needed daily).
