I used to hate pinning quads. Had a few bad injections because I didn't know any better. But pinning anywhere in the Glutes is just a pain anymore. I've returned to quad injections but use slin pins for the most part as well as everyday injections and I will never go back to injecting anywhere else. So much easier and you don't have to worry about scar tissue build up near as much. My ass got so much scar tissue that after a while it was crunchy when I'd stick the needle in and it was difficult to actually squeeze the oil out of the syringe.
