I think I already know the answer, but here's the question. I have a pulled muscle in my shoulder. I have been on HGH for about 5 months, currently at 4 iu/day 5/2 doing sub-q injections twice daily. Would there be any benefit to do my injections temporarily into the affected muscle (IM) for any site muscle/repair benefit? Or is it just systemic in its effetciveness and would not matter? Any thoughts/studies/personal opinions appreciated!
