I am currently pinning 2x a week subq in my stomach. This is fine but I am getting tired of having bumps on my stomach. I would like to consider switching to the delts every other week. Would this be acceptable? and would a 25g 5/8 needle be sufficient for the deltoid or do I need an inch. Also I could consider switching back to glutes but finding supplies not at the pharm may be hard for me.
