I use a 1.5" 23 g for ass pins. I hit the right glute this morning. I always pin high on the glute and on the outer quadrant of the cheek. I'm about 14% bodyfat so I'm probably fine, but this morning I went in a little more sideways than preferred. Probably a 60 degree angle instead of 90. The injection hurt as soon as i punctured the skin and of course there was some blood after pulling out. Yes I aspirated. What I'm concerned about is not getting the needle in deep enough to my glute muscle. It was a poor injection and I'm pissed. Anybody else do this on occasion? No need to repin is there?
