A subcutaneous (“subcut” or SubQ) injection goes into the fat layer just under the skin — the method used for many GLP-1s, insulins and peptides. Here is a general, plain-English walkthrough. This is educational only; get hands-on training from a nurse or pharmacist, and always follow your product’s instructions.
Subcutaneous sites have a fat layer you can gently pinch: the abdomen (about two inches away from the navel), the front of the thighs, the back of the upper arms, and the “love handle” area. Rotate sites so you don’t use the same spot repeatedly.
A little bruising or a small bump can happen; rotating sites helps. Dispose of needles only in a proper sharps container — never in the household trash.
Usually 45 to 90 degrees. A short pen needle typically goes straight in at 90 degrees; a longer needle may be angled at 45. Follow your product’s guidance.
Sites with a pinchable fat layer: the abdomen (about two inches from the navel), front of the thighs, back of the upper arms, and the love-handle area. Rotate sites.
Usually yes — gently pinching lifts the fat away from muscle so the injection stays subcutaneous. Follow your device’s instructions.
No. Use a new needle each time and dispose of it in a sharps container. Reusing needles is unsafe.
Usually only a small pinch. Letting the alcohol dry, relaxing the muscle, and rotating sites all help reduce discomfort.
