So what are your guys thoughts on creatine? I've been using the Aldi brand protein powder to make a recovery drink for the last couple weeks and I just realized that the protein powder had creatine in it. I've been feeling pretty good on the bike, but what effects should I expect, if any, from the creatine? I remember a friend taking it in high school and having big time stomach issues but this stuff doesn't seem to be bothering me. Does that mean that its not really enough concentration to have any effect?
