I have heart valve leak problem and I am taking medicines. No complication. I started gym .Its four months now. When ever I asking for a protein supplements or is it ok for me to use that no one replying and suggesting me food diets. I am not lean but to be bit muscular I think my normal food intake not do anything. And for a middle class I can not afford nutritious food diets on a daily basis. Thats why I need to know about proteins like whey. If any problem in using creatinine or whey proteins? This time I hope a solution for my question. Thank you
