I am sure this question is asked millions of times, but here it goes again. So I purchased some Whey Protein, and one day while I was making my shake, I noticed in fine print, saying that creatine is part of the recovery formula that they added.
Now, I hear good things and bad things about creatine, and I am still not sure if I should be worried or not. Some say creatine is harmless when it is not abused, others say creatine is a hardcore kidney killer. Can I get some feedback?
