Where to inject NAD+
No use in people is FDA-approved; it is sold as a research chemical. Because there's no FDA label, no official list of sites exists; for a shot under the skin, general advice points to the belly, front of the thigh or back of the upper arm.
- Belly: stay at least 2 inches from the belly button; choose a spot where you can pinch the skin.
- Front or outer thigh: use the middle section, which sits between your knee and hip.
- Back of the upper arm: this is easier when someone else gives the shot.
Injecting NAD+, one step at a time
- Clean your hands with soap and water, then use an alcohol swab on the injection site.
- Fill the syringe to the right line; if you're unsure about units, check the calculator.
- Pinch up a fold of skin. Insert the needle at the angle shown by your prescriber, then push the plunger slowly.
- Remove the needle, press lightly with a cotton ball and place the syringe in a sharps container.
Rotating your injection spots
Choose a fresh spot for each dose, at least an inch away from the previous one. Rotating spots reduces the risk of lumps or pits beneath the skin. Avoid skin that feels sore, looks bruised or red, or has scars.

Questions people often ask
Does the injection site matter for NAD+?
For shots under the skin, people usually choose the belly, thigh or upper arm. Use one area and rotate spots there, unless your label or prescriber tells you to do otherwise.
Should I pinch my skin?
Ask your prescriber about it; the labels we list leave that choice to them. It's common for people to pinch a fold of skin when using short insulin needles.
