I know it's proper protocol to switch injection sites for every pin. But I'm right handed and find it easier to pin my right glute. And so far no pip at all with E. So, that's what I've done my first 5 pins. The one time I tried pinning in my left glute I must have hit a vein or something and got an abcess. So, is there any issues or hazards of just pinning in the same area all cycle or is best to switch between glutes and quads and so on?
