Glutes are the easiest to pin. Big muscle group, not extremely vascular. If you find it uncomfortable to twist around then your proply too fat to shoot juice anyways! But stand in front of a mirror find the spot, some like high on the hip some lower and more interior area really no different, relax and that's real important relax your muscles in your ass and stick that bitch quick and steady. Don't get nervous and shake around just relax and slowly push the plunger. The needle won't break off, if you hit a blood vein it will stop bleeding very quickly, and there is not a lot of nerves in the side and lower side of the glutes. Main thing is just relax do not tense up and keep it all super clean ! No problems
