Least painful and most safest places to pin are glutes and deltoids but you end up running out of injection sites eventually.
I agree. And also when you press the plunger to get the air out and some of the oil runs down the needle, the benzyl alcohol can cause stinging. Most instances I don't have a problem. But every once in a while I'll get one that is super painful from the burning/stinging sensation. Most times it's from the alcohol still being wet on the skin, other times the benzyl alcohol. I only pun delta and tris daily, so this phenomenon happens everywhere.
