I have been playing football for 3 years and I am currently a sophomore in high school And i am currently second string and the person in front of me is like a 210 pound senior. I am currently 160 pounds and I need help so I can gain muscle mass as fast as possible, I am wondering if there are certain vitamins and protein products I should use. I don’t want to use anything that has bad side affects such as acne and shrinkage because in high school you just want those kind of things if you know what I’m saying.
