A subcutaneous injection goes into the layer of fat just beneath your skin, not into muscle or vein. The needle on an insulin syringe is short and fine — most people barely feel it. Here's the calm, clear version.
The best sites
You want areas with a bit of fat you can pinch. The standard rotation:
- Abdomen — the easiest and most common. Stay at least 5cm (two inches) away from your belly button.
- Outer thigh — the front-outer part, where there's a fat layer.
- Back of the upper arm — the fatty area, harder to reach yourself.
- Love handles / flank — plenty of subcutaneous fat.
The technique
Wash your hands and swab the site
Clean hands, then wipe the injection spot with an alcohol swab and let it dry.
Draw your dose
Draw the number of units the calculator gave you. Flick out air bubbles and push them back into the vial.
Pinch the skin
Gently pinch a fold of skin and fat between your thumb and forefinger. This lifts the fat away from muscle.
Insert at 45–90°
With a short insulin needle, 90° (straight in) is fine for most people. If you're very lean, use 45°. One smooth motion — don't jab slowly.
Push slowly, then withdraw
Depress the plunger steadily, count to three, then pull the needle straight out. Release the pinch.
Done — dispose of the needle
Drop the used syringe straight into your sharps container. Light pressure on the site if there's a tiny spot of blood.
Rotate your sites
Don't inject the same exact spot every time. Move around — different quadrants of the abdomen, alternate thighs. Rotating prevents irritation, lumps, and tissue buildup. A simple rule: imagine a clock on your stomach and move to a new "hour" each injection.
That's normal. The first one is the hardest and it's almost always anticlimactic — most people say "that's it?" afterward. Go slow, breathe out as you insert, and remember the needle is shorter than a grain of rice is long. WhatsApp us if you want to talk it through before your first one.
