I still do delts 90% of the time, and no issues at all. With that said, I use Adequan for my arthritic knee joints (it's a big-volume IM injection; 9cc), and that one goes in the ventro-glute with a 1.5" needle. Somebody dared me that I wouldn't have the balls to use a 14-gauge (cattle) needle for that, and I took the dare... No problem! http://youtu.be/nzVkyWuIujI
