Holding a NAD+ pen for the first time can feel intimidating. It shouldn't. Using a NAD+ pen at home is genuinely one of the simplest at-home wellness routines — no mixing, no measuring, no clinic appointment. Once you've done it once, it becomes a calm two-minute habit.
This UK guide walks you through exactly how to use a NAD+ pen at home, from prep to dose to safe disposal, in plain, reassuring steps.
How to use a NAD+ pen at home
- Wash your hands and let the pen and cartridge reach room temperature (2–3 minutes).
- Assemble: insert the cartridge, attach a fresh micro-needle, prime as instructed.
- Clean the site with an alcohol wipe (rotate sites each time).
- Dial your dose in units, then administer slowly and steadily.
- Remove the needle, apply gentle pressure, and dispose of the needle in a sharps bin.
- Store the pen/cartridge per the label (typically refrigerated, away from light). - RevIVe NAD+ is clinician-grade, COA-certified (99.5%+ purity), UK-based, and founded by a qualified aesthetics practitioner. - NAD+ injectables are not MHRA-licensed. For wellness support only. Always consult a healthcare professional first.
Before you begin: what's in your kit
Every RevIVe NAD+ Pen Starter Kit is designed so you can start with confidence. Lay everything out on a clean surface first:
- The reusable NAD+ pen device
- Your pre-loaded, COA-certified NAD+ cartridge
- Sterile single-use micro-needles
- Alcohol wipes
- A sharps bin (or know where to get one — see below)
Having it all ready before you start keeps the process smooth and unhurried.
How to use a NAD+ pen at home: step-by-step
Step 1 — Wash your hands and warm the pen
Wash or sanitise your hands thoroughly. Take the pen and cartridge out and let them sit at room temperature for 2–3 minutes. A cartridge injected straight from the fridge can feel colder and less comfortable — a short warm-up makes it gentler.
Step 2 — Assemble the pen
Insert the NAD+ cartridge into the pen. Attach a fresh, sterile micro-needle and prime the pen as described in your kit instructions to clear any air. Always use a new needle each time — never reuse.
Step 3 — Choose and clean your site
Common subcutaneous sites are the abdomen (a few centimetres from the navel) or the upper outer thigh. Wipe the area with an alcohol swab and let it air-dry. Rotate your injection site each time to keep skin comfortable and avoid irritation.
Step 4 — Dial your dose
Turn the dial to your chosen dose in units. Because the concentration is pre-set in the cartridge, there's no maths and no drawing up. Many people follow a short loading phase (once daily for the first few days), then move to every-other-day support of up to 50mg — but follow the guidance with your kit and your healthcare professional's advice.
Step 5 — Administer slowly and steadily
Position the pen against the cleaned site and deliver the dose slowly and steadily (roughly ten seconds). A gentle, unhurried pace is the most comfortable approach. Do not aspirate for subcutaneous use.
Step 6 — Aftercare
Once complete, set the pen down and apply gentle pressure with cotton wool if needed. There's no need to rub. A little redness can be normal; rotating sites helps.
Step 7 — Dispose of the needle safely
Place the used micro-needle straight into your sharps bin. Never put needles in household waste. When the bin is full, your pharmacy, GP surgery, or local council can advise on collection or disposal.
How to store your NAD+ pen and cartridges
Storage protects the potency you paid for.
- Keep cartridges refrigerated (typically 2–8°C) and away from direct light, unless your label says otherwise.
- Don't freeze.
- Note any "use within" period after first opening.
- Always check the expiry date and the specific instructions supplied with your RevIVe kit — these take precedence over general advice.

Feeling nervous? That's normal
The most common feedback from first-time users is relief: "That was easier than I expected." The micro-needles are fine and short, the pen does the measuring for you, and the whole routine takes minutes. Go slowly, breathe, and you'll quickly build confidence.
If you're still unsure, that's exactly the moment to speak to a healthcare professional — and to lean on a supplier who takes quality seriously.
