i just do glutes and delts, with 2 inch 18 gauge needles, i just push the needle in about 1 inch and a piece for the delts. some people don’t like big needles, i dont really care. doesn’t hurt that bad. im a medic, so i get these big ones free. who turns down free stuff? not me. i like injecting the glutes more though, i dont even feel it.
