I'm working on bulking right now, and was wondering if there was much difference between brands on protein and creatine. I.E. is Weider Creatine Capsules, as good as Six Star Professional Strength Creatine Capsules. I am already taking Amino's, so I didn't know if that was the difference in the two or not. Also, are certain whey proteins better than others?? Right now I'm using Six Star Whey Protein, I'm okay with the taste, but wondering if it is good enough. 25g per 4oz. serving.
