I started with abdominal injections for about a year, then rotated to the hips/flanks for another six months. Over time, as body fat decreased in those areas, injections became more sensitive and less comfortable.
So far, upper outer glute/buttock subcutaneous injections have worked best for me. I alternate sides and stay in the fatty tissue.
In general, most peptides that are intended for subcutaneous use can be injected into the abdomen, upper thigh, hips/flanks, or upper outer glute area. Rotation matters more than the specific peptide for most people, since repeatedly using the same spot can lead to irritation, tenderness, or scar tissue.
One thing to be careful about with glute injections is avoiding the central/inner areas where larger nerves run deeper .... especially the sciatic nerve. With a shallow subq insulin pin and proper placement in fatty tissue, the risk is low, but hitting an irritated area can definitely be painful and is something you notice immediately.
