What is the second safest spot to inject, I did it in my ass but I have scar tissue now. So should I inject in my delts, and what kind of pin should I use?
You don't have scar tissue, you just have a bit of swelling. Thisi s week 4 of your 1st cycle correct? That means there's no way you could have done any more than 10 injections. Just keep hitting your glutes, you're a long ways from scar tissue.
