OK, this may be a dumbass question but I was wondering anyway. I use creatine monohydrate and a whey protien supplement but I still consider myself natural. My friend was over the other day and told me that he was dissapointed and thought that I was natural until he saw the creatine container. He also told me that it was horrible for my liver. I wanted to smash his skinny ass but after he left I wondered about what he said. If I use creatine and protien supplements can I still consider myself natural? And what effects does creatine have on the liver?
