I just started my therpy last week and I am aiming to do IM injections on my M,W,F schedule. I have been using a 25 gauge 5/8" needle to draw and inject into my quads. I have read about a lot of people using the easy touch insulin syringes/needles to inject. I figured either of these would hit IM if done in the delts or elsewhere if the person were lean. I do carry a bit more body fat and I am just concerned with the 5/8 or 1/2 inch needles not being IM, especially in my quads. Is using a 1 inch needle overkill? Should a 5/8" needle suffice to hit the muscle in both the quads and VG? I know similar questions have been asked, but most of the stuff I've found is in regard to people who state they are fairly lean, not the other way around. Thanks everyone! Sorry for asking another common question in just a slightly varied manner.
