01 — How to use
How to use your NAD+ Injection Pen
The full injection ritual, step by step — the pen makes it simple and repeatable.
-
01
Load your vial
Insert a 1000mg pre-mixed NAD+ vial into the pen, following the illustrated guide.
-
02
Fit a fresh needle
Attach a new 31G (6mm) micro-needle. Always use a fresh needle for every injection.
-
03
Dial & prime
Set the pen to your dose and prime it until a small drop appears at the needle tip to clear any air.
-
04
Clean the site
Pick a fatty area — lower stomach, hip or buttock — and clean with an antibacterial wipe. Rotate sites daily.
-
05
Inject
Pinch the skin, insert the needle at 90° into the fatty tissue and press the plunger fully. Hold a few seconds, then withdraw.
-
06
Dispose safely
Drop the used needle straight into the sharps bin. Never reuse or share needles.
Protocol: inject once daily for five days, then take two rest days. Store your NAD+ vials refrigerated.
02 — FAQs
Frequently asked questions
The questions customers ask most. Anything missing? Talk to us.
Is the NAD+ Injection Pen reusable? +
Yes. The pen is a reusable auto-injector — you replace the single-use needles and the NAD+ vials, not the device itself. With basic care it's built to last.
Do I need vials and needles as well? +
Yes — the pen is the delivery device on its own. It pairs with our 1000mg pre-mixed NAD+ vials and 31G (6mm) micro-needles. If you want everything together, the NAD+ At-Home Kit includes the pen plus a month of vials and consumables.
How does the pen work? +
You load a vial, fit a fresh needle, dial your dose and inject subcutaneously. The click-stop mechanism gives precise, repeatable dosing, and the needle stays covered until you fit it.
How do I care for and store it? +
Wipe the exterior clean, never share your pen, and keep it in the insulated travel case between uses. Store your NAD+ vials refrigerated.
What's the difference between this and the At-Home Kit? +
This is the pen device on its own — ideal as a replacement or spare. The NAD+ At-Home Kit is the full starter bundle: pen + 2× 1000mg vials + needles, wipes, sharps bin and travel case.

Solid, reliable device. Took one go to get the hang of loading a vial and then it's simple.
