Im 16, and i play football as well as your son, I dont know much at all about lifting and supplements, but I have heard that Thermogains, and this new Nitric Oxide, isnt that good for someone under 20 or so, It sounds like your sons pretty awesome though 155 himself and benching 240, thats not bad at all. I dont know if hes on creatine or not, but I heard that someone his age and my age will actually create the things creatine gives you untill you turn about 18 or 19. Im just saying what I heard, and ive heard it from a very reliable person I think, My coach, a bodybuilder as well. But as someone said before, your son should start to eat a little more fat, Im a lineman, I dont know what your son plays but hes probobly extremely explosive and that will help him so much, espesially when he gets a couple more pounds on him, he will be able to just throw other players around like rag dolls......fun!
