IMO i no i'll prob get ridiculed here but my first cycles when I was delving into test and d-bol for highschool football was when I was 16, it's fine if u run ur cycle right, pro-hormones are weak compared to that shiat. 14 is a little young but i don't think the hormone issue ithe problem, i got tested by my doc and everything and i recovered fine. If he runs this atleast help him out and get him some proper pct of toremefine. I remember how it was, football is life and nothing will stop u from being the best, it's f'ing highschool, clicks, shallow people and people take on "movie roles". I think the biggest thing to worry about is the joint, ligament and bone damage. In personal experience tell him his body hasn't grown enough to support that muscle growth and to expect injuries. Also tell him nothing will do as much for him as gaining speed, thats what coaches want. Tell him to just up his protein intake and wait until jr. year, best advice to really make him stop now, as he has already made the decision and will be running them eventually.
