hell no i dont care....im younger than most using HGH, im turning 27 here in a couple months.....i started using HGH right after my third surgery from a bad motorcycle accident, i had bone grafts from my hip put into my foot, wrist reconstructed, knee reconstructed, so i started on it right after that. this is the first time i've been on it and had my training and diet in perfect order and also had my body in 100% working condition from the surgeries......im planning on staying on it all year......i think the results are just now showing at their best
