The pen route: a reusable auto-injector and two pre-filled 500mg cartridges, so every dose is a turn of the dial and a click, with nothing to draw up or measure by eye. Twenty doses at 50mg, about five weeks on the standard protocol.

The ritual, fully equipped. A precision auto-injector pen, two sealed 500mg cartridges of pure NAD+, and every consumable the month asks for — nothing else to order, nothing to figure out.

What's in the box

  • 1 × refillable auto-injector pen with click-stop dosing
  • 2 × 500mg / 3ml NAD+ cartridges (20 doses in total)
  • 20 × sterile, individually wrapped micro-needles
  • 20 × antibacterial wipes
  • Step-by-step instructions printed inside the lid
  • Certificate of Analysis available on request

The pen, both cartridges and every consumable arrive in our rigid presentation box, each in its own place, with the full dosing sequence printed inside the lid.

Before you start

How to dose, how to store it, and whether it's right for you.

How to use it

Each cartridge holds ten 50mg doses (0.3ml). Most people start with one dose daily for the first three days, then move to every other day — twenty doses across the two cartridges, around five weeks at that rhythm. Take the cartridge out of the fridge 20–30 minutes before you seat it; cold solution stings more than it needs to. Wipe the site, pinch a fold of skin on the stomach, hip or outer thigh, go in at 45°, and rotate where you dose each time.

This protocol reflects common practice and what customers tell us, not clinical proof. Confirm your dose with a licensed prescriber. The reasoning behind the 50mg dose is in our NAD+ dosage guide.

Good to know

  • Storage: cartridges live in the fridge. The pen, box and consumables are happy at room temperature.
  • Shelf life: 12 months unopened.
  • Colour: clear to faintly yellow is completely normal — that tint is the NAD+ itself.
  • How it feels: a brief warmth or mild sting during the dose is common and passes in seconds. The occasional small bruise is nothing to worry about.
  • Travel: NAD+ holds up at room temperature for several weeks, so a trip won't ruin it.

Is it for me?

Adults 18+. Not suitable during pregnancy or breastfeeding, or if you have a current or previous cancer diagnosis, an organ transplant, immunosuppression, a heart-rhythm condition such as atrial fibrillation, a recent skin graft, or significant liver or kidney impairment. If you take prescribed medication or you're unsure, speak to your doctor before starting.

Not sure which kit?

02 — Benefits

Why NAD+

NAD+ is the coenzyme your cells use to make energy and repair themselves. It falls year after year from your late twenties. Replenishing it directly is the closest thing science has to a cellular reset.

01

Cellular Energy

+

NAD+ fuels the mitochondria — the engines inside every one of your cells. Raising NAD+ lifts ATP production for sustained energy that doesn't depend on stimulants.

The engine, not the stimulant
02

Mental Clarity & Focus

+

NAD+ is a cofactor in the synthesis of neurotransmitters tied to attention and mood. People report cleaner focus and less afternoon fog.

03

Faster Recovery

+

Effort depletes NAD+ stores. Replenishing them shortens the recovery window after training, travel and high-load weeks.

04

Longevity & DNA Repair

+

NAD+ activates sirtuins — proteins associated with cellular longevity, DNA repair and metabolic regulation.

Backed by sirtuin research
05

Deeper Sleep

+

NAD+ helps regulate the circadian rhythm via the SIRT1 pathway, supporting cleaner sleep and mornings that don't feel borrowed.

06

Skin & Visible Ageing

+

Visible markers of ageing track cellular energy decline. Restoring NAD+ supports the machinery that keeps skin functioning the way it did a decade ago.

03 — How to use

How to use your NAD+ Discovery Kit

Loading the pen is the only part that feels new, and only the first time. Here's the whole ritual, start to finish.

  1. 01

    Take it out of the fridge

    Twenty to thirty minutes before you dose, bring the cartridge up to room temperature. Cold solution stings more than it needs to.

  2. 02

    Seat the cartridge

    Open the pen, drop in a 500mg / 3ml NAD+ cartridge and screw it closed. One cartridge covers ten doses before you swap it.

  3. 03

    Fit a fresh needle

    Attach a new sterile micro-needle. Always a new one — never reuse, never share.

  4. 04

    Dial and prime

    Set the pen to 0.3ml and prime until a small bead appears at the tip. That clears any air in the line.

  5. 05

    Clean, pinch, inject

    Wipe a fatty area — lower stomach, hip or outer thigh — pinch a fold of skin, insert at 45° and press the plunger all the way down. Hold a few seconds before you withdraw. Rotate the site every time.

  6. 06

    Dispose safely

    Drop the used needle straight into the sharps bin. Cartridge back in the fridge, pen back in the box.

Protocol: one dose daily for the first three days, then every other day. Each cartridge holds ten 50mg doses (0.3ml) — the two cartridges cover roughly five weeks. Keep cartridges refrigerated; they stay stable at room temperature for several weeks.
04 — FAQs

Frequently asked questions

The questions customers ask most before starting. Anything missing? Talk to us.

What's actually in the kit? +

A refillable auto-injector pen, two 500mg / 3ml NAD+ cartridges (1000mg and 20 doses in total), 20 sterile micro-needles, 20 antibacterial wipes, a sharps bin and a quick-start guide, all in a rigid presentation box. Nothing else to buy to get started.

How long does one kit last? +

Each cartridge holds ten 50mg doses. Following the usual protocol — daily for three days, then every other day — the two cartridges cover about five weeks. Dose more often and it goes faster; that's what the single 500mg cartridge top-up is for.

Does it hurt? +

The needles are ultra-fine and go into fatty tissue, so most people feel a light pinch and nothing more. Letting the cartridge warm up out of the fridge first makes a noticeable difference, as does rotating where you dose.

When will I notice anything? +

Most people describe steadier energy and cleaner focus within the first two to three weeks. It isn't a stimulant — the effect is a floor that stops dropping rather than a spike.

How do I store everything? +

Cartridges in the fridge. The pen, box, needles and wipes are fine at room temperature. NAD+ holds up at room temperature for several weeks, so travel isn't a problem. Unopened cartridges keep for 12 months.

What happens when I run out? +

You keep the pen. From then on you only reorder the NAD+ Pen Refill Kit — two cartridges plus consumables — or a single 500mg cartridge if you just need a top-up.

Who shouldn't use it? +

Adults 18+ only. Not suitable during pregnancy or breastfeeding, or if you have a current or previous cancer diagnosis, an organ transplant, immunosuppression, a heart-rhythm condition such as atrial fibrillation, or significant liver or kidney impairment. This product is not intended to diagnose, treat, cure or prevent any disease. If you take prescribed medication or you're unsure, speak to your doctor before starting.

More energy without the crash

Three weeks in and the afternoon slump is basically gone. The pen is easier to use than I expected.

Cheaper than the clinic, same feeling

I used to book IV drips. This is a fraction of the hassle and I get the same benefit at home.

Tom H.✓ Verified customer
★★★★★

Travelled with it, no drama

Took it to Lisbon for two weeks and never broke the rhythm. The cartridges were fine at room temperature.

Alina G.✓ Verified customer
★★★★★

Clear instructions

Took me a couple of goes to get comfortable with the routine, but the guide is genuinely good. Sleeping better overall.
