Hey, im new to this and i just have a couple questions. Im 14 and i started working out about 3 months ago, no supplments and eating good (well expect a multi-vitamin). Before i started working out i wrestled 130 weight class and now after working out for 3 months i weigh 138 and look noticably better. I was looking at muscle milk the lady at GNC reccomended it, as i am 14 i would probably only take 1 scoop not the reccomended 2 cause of my age. If muscle milk is not suitable for me could you please list something that would help build mass combined with working out/good diet. Thank you.
