I'm 23, 174 pounds @ 5'7". I've been on growth now for 7 weeks along with sust 250. I'm taking the sust to gain mass n strength while taking the growth to get cut and gain lean mass ( also starting to get thinning hair, and hoping that after about 5 or 6 months it could start to help that). But I was talking to a knowledgeable guy at the gym n he said I'm waisting my time on the growth at my age, and should just be taking a cutter with my sust. What is your take on my situation? Am I doing the right thing... P.s I have been doing 3 IU's a day.
