Hey guys, quick question. I know I'll get the best answer here. My son is almost 17 he has been to the gym with me for the last 3 summers. He wants to go full time now. Is it ok for him to take creatine , bcaa's and protein shakes or should I stay clear of any of those because of his age. I know I took that stuff plus more back then but I didn't have anyone to guide me besides my friends. Any thoughts or answers will be appreciated. Thanks!
