TweetI inject glutes about 4 inches below the kidney area, with a 1.5" needle and rotate the area. I find a 23guage works best. 25 guage is just to slow and hard to push in. Just take the skin around injection site and stretch it to make it taunt. Take needle and just push it in don't screw around going slow. After injection, pull the needle out fast at the same time releasing the skin. I have very little if no bleeding or leakage this way.
