I would like to mix up my pinning spots so instead of the buttocks I want to go to the deltoids. Do I need to change my needle to inject in the deltoid because it’s a smaller muscle than the butt?
1" covers it all. And rotating injection spots is a very good idea. You almost have to when doing daily or EOD injections. DeltsX2, glutesX2, pecsX2, quadsX2, work for me. I've not been brave enough for calves yet. After a while there's nothing to it and you just pin, no problemo.
