I recently ordered some Creatine from Optimum Nutrition that is made with Creapure. In the time I've spent waiting for it to arrive, I've been reading some stuff about it, like it has dangerous side effects such as kidney damage and hair loss etc. Now to be honest I'm a fairly paranoid person when it comes to my health and what I put into my body. I certainly don't want kidney damage or hair loss. Are my fears warranted or am I just being paranoid?
