Is insulin syringe 29G 1/2" sufficient enough to reach deltoid muscle? I am swichting to insulin syringes, but i’ve been doing IM injections all the time and i don’t want to change that. I will be doing injections more to the side of deltoid, where the muscle is sticking out the most when i flex my delts. I am not lean (just started slight cut), but i don’t think this is a place where fat accumulates. What do you guys think?
