I find glute injections painless. With quad injections, however, I have had pain AFTER the shot every single time. The whole area around the injection site turns red for an area about the size of the palm of my hand and stays that way for a couple of days and it hurts like hell to walk. The shot itself doesn't hurt but afterwards, forget it! And I doubt it is technique as I have given thousands of injections and know how and where to do them. It also isn't the gear as it is U.S. made pharmaceutical right from the pharmacy. I guess we are all different though and some places work better in some than others.
