Hey I've sat around getting decent gains without supplements or special powders and watched my friends take Creatine and Protein Whey. I heard Creatine is harmful to your kidneys and so did my friends therefore most of them stopped using it, but this protein powder is begining to come into the school weightroom now and I was wondering if it was harmful to anything like Creatine, because creatine sounded like harmless body making substance untill students were discovering the kidney fact. If I started using Protein after being natural all this time and gaining so much natural muscle make me have huge gains when I start using it?
