I am currently helping a friend of mine get into the weight game, but not only is the kid 23 years old is 5'11 and weighs 155 pounds, but also has serious Kidney issues. I think he has has 10 kidney stones in the last 6 years. His doctor suggested that he try to limit his animal protein which is detrimental to his ability to gain any muscle!
I dunno if whey protein is considered a dirivative of animal protein and whether it will have any ill affects on his kidneys. Can someone with some knowledge help me out here?
Also I wanna get him on some Creatine, but heard that is terrible on the kidneys as well, is there an alternative that will help him gain some mass??
