If you bust your ass hard enough you still get sore. The real question is wether it is digested properly or just passed. I guess when they change the form like they did with the creatine ethyl ester it will make it more efficient. I take it not because it makes me feel different but because ive read stuidies that show it is very beneficial in recovery. Ill tell you that if your looking for the miracle supp its not glutamine.
