More Than One Side To Creatine!
Creatine has shown in lab studies that over the span of a lifetime, creatine usage can lead to leukocyte build up in the liver. Leukocyte buildup suggests premature stages of cancer. Also the negative effects of creatine are, GI distress, which includes intestinal cramping, diarrhea, increased urination, which leads to dehydration.
Does it work?
Of course but be fair to the people who are reading this site. And SASH, creatine monohydrate is the same across the brand, just ensure that your product is made in Germany or the US. Extra Creatine does not mean its good, during the maintenance stage you only need 0.03g per kg bwt.
If your buying the cheap stuff from China then it can depend on the brand. Do your research before you decide if creatine is right for you!
