1. Side Effects Written by Guest on Tuesday, 05 December 2006 Hi, I hear that there is no long-term reasearch on creatine and that it mayb unsafe. My football buddies told me that it will eventually shut down your kidneys and that it makes it so that the body doesn't create its own creatine anymore. My friend's brother was on creatine and he asked his doctor and the doctor said the same thing. Is this true? |
