Ten doses was enough to decide. Ordered the refill on day twelve.

The smallest honest way to find out what NAD+ does for you. A real pen, a real 500mg cartridge, ten full doses — around two and a half weeks. Long enough to feel the difference, short enough that you're not betting a month on a maybe.
Everyone's baseline is different, and so is everyone's response. Rather than ask you to take our word for it, this kit hands you the whole system at trial size: the same auto-injector, the same pharmaceutical-grade NAD+, the same five-minute ritual. If it works for you, step up to the full kit or a refill and keep going.
What's in the box
- 1 × refillable auto-injector pen with click-stop dosing
- 1 × 500mg / 3ml NAD+ cartridge (10 doses of 50mg)
- 10 × sterile, individually wrapped micro-needles
- 10 × antibacterial wipes
- 1 × sharps bin for safe disposal
- 1 × illustrated quick-start guide
How to use it
Start with one 0.3ml dose daily for the first three days, then move to every other day — ten doses, roughly two and a half weeks. Some people settle at once or twice a week after that; there's no prize for going faster. Let the cartridge warm up out of the fridge for 20–30 minutes first, dose at 45° into the stomach, hip or outer thigh, and rotate the site each time.
Good to know
- What's in the cartridge: pure nicotinamide adenine dinucleotide and sterile solution. Nothing else.
- Storage: cartridge in the fridge; pen and consumables at room temperature.
- Shelf life: 12 months unopened.
- How it feels: most people report feeling alert rather than anything dramatic. A brief warmth or mild sting during the dose is common and passes in seconds.
- The pen is yours to keep — refills fit it from here on.

01 — Benefits
Why NAD+
Before you commit to a month, it's fair to want to know what you're committing to. Here's what NAD+ does — and this kit is the smallest honest way to find out whether it does it for you.
01Cellular 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
02Mental Clarity & Focus
+
NAD+ is a cofactor in the synthesis of neurotransmitters tied to attention and mood. People report cleaner focus and less afternoon fog.
03Faster Recovery
+
Effort depletes NAD+ stores. Replenishing them shortens the recovery window after training, travel and high-load weeks.
04Longevity & DNA Repair
+
NAD+ activates sirtuins — proteins associated with cellular longevity, DNA repair and metabolic regulation.
Backed by sirtuin research
05Deeper Sleep
+
NAD+ helps regulate the circadian rhythm via the SIRT1 pathway, supporting cleaner sleep and mornings that don't feel borrowed.
06Skin & 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.
02 — How to use
How to use your NAD+ Discovery Kit
Everything here is the same as the full kit, just at trial size. Your first dose will be the hardest, and it won't be hard.
-
01
Take the cartridge out of the fridge
Twenty to thirty minutes before your first dose. Warm solution is far more comfortable than cold.
-
02
Seat the cartridge
Open the pen, drop the 500mg / 3ml cartridge in and screw it closed. It stays there for all ten doses.
-
03
Fit a fresh needle
A new sterile micro-needle every single time. Ten are included — one per dose.
-
04
Dial and prime
Set the pen to 0.3ml and prime until a small bead appears at the tip, clearing any air.
-
05
Clean, pinch, inject
Wipe a fatty area — lower stomach, hip or outer thigh — pinch a fold of skin, go in at 45° and press the plunger fully. Hold a few seconds, then withdraw. Rotate the site each time.
-
06
Dispose safely
Needle into the sharps bin, pen back in its place, cartridge back in the fridge.
Protocol: one dose daily for the first three days, then every other day — ten doses, roughly two and a half weeks. Keep the cartridge refrigerated; the pen and consumables are fine at room temperature.
03 — FAQs
Frequently asked questions
The questions customers ask most before starting. Anything missing? Talk to us.
What exactly do I get? +
A refillable auto-injector pen, one 500mg / 3ml NAD+ cartridge (ten 50mg doses), ten sterile micro-needles, ten antibacterial wipes, a sharps bin and an illustrated quick-start guide. Nothing else to buy to get started.
Is the NAD+ the same as in the full kit? +
Identical. Same cartridge, same pen, same protocol — there's just one cartridge instead of two. The only thing you're trying at a smaller scale is the commitment.
Will ten doses be enough to tell? +
For most people, yes. Two and a half weeks is long enough to notice whether your energy and focus have a different floor. Some effects — recovery, sleep, skin — build over longer use, so a first cartridge tells you whether it's worth continuing rather than the full story.
What do I buy next? +
You keep the pen, so from here you only ever buy NAD+. Most people move to the two-cartridge Refill Kit; if you dose lightly, a single 500mg cartridge may be all you need.
What's in the cartridge? +
Pure nicotinamide adenine dinucleotide and sterile solution. Nothing else added.
Does it hurt, and will I feel odd afterwards? +
The needles are ultra-fine and go into fatty tissue — most people feel a light pinch. During the dose a brief warmth or flush is common and passes in seconds. Most people report feeling alert rather than anything dramatic.
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.

Glad I didn't start with the big kit
Wanted to know I'd actually stick with it before spending three hundred quid.
★★★★★
Noticeable by week two
Nothing dramatic on day one. By the second week I was clearly sharper in the mornings.
★★★★★
Keeping the pen makes it a no-brainer
You're basically paying for the NAD+ and getting the hardware thrown in.
