What UI should I run for HGH thats still effective but safe?

[irlgreycel]

I plan on running test e with hgh, I just don't know how hard I should take it. I'm 15, 5'11, ~190lbs, with decent muscle. I thought about IGF-1, if my goal is to maximzie frame, height, and muscle? I just need help with all of this.
Edit: If I used IGF-1 would I swap out hgh?

4IU is good. You can use 3IU as well. 3IU is minimal but noticeable. You should note, it isn't a linear chart of dose and effect. The more you increase it, the rate of effect increase dampens. So 6IU and 8IU are much closer in effect than 2IU and 4IU.
