I'm looking to gain some muscle of this HGH too however my most important reason is to help heal repair some tendons and joint problems. Is 4 iu's a day well enough to see these results? And do i need PCT for the test if i'll be using hgh in week 8? I just dont wanna drop like a rock ya know. And on emore thing...is 5 on 2 off good for the HGH
