I have a pretty fat ass, so when I do glute shots I can't help but wonder if my 1.5" needle is even getting into any muscle. It doesn't hurt at all and is completely painless. When I do any other shot I can at least feel it somewhat.
So, what happens if you are injecting into fat and not muscle? I've read that your body still absorbs it, just at a slower rate. I figured I'd make sure since I don't want to be wasting my gear on shots that aren't even doing anything.
