NAD+ AT HOME Injection Pen Kit 1000mg
The at-home, self-injectable wellness kit everyone's talking about. Pharmaceutical-grade NAD+ that boosts energy, clarity and skin repair, replenished on your own schedule.
ISO-certified labs · ~100% bioavailability · Discreet, tracked UK dispatch
Description
The NAD+ Pen is a revolutionary delivery system that allows near-100% bioavailability of Nicotinamide Adenine Dinucleotide (NAD+) a critical coenzyme that powers energy production, DNA repair, and cellular resilience.
Unlike oral supplements, which are largely degraded in the digestive system, the NAD+ Pen delivers NAD+ directly beneath the skin via painless subcutaneous micro-injections.
This ensures rapid cellular uptake and maximum potency, giving you clinical-grade results in the convenience of your own home.
Key Benefits:
Restores declining NAD+ levels for sustained energy and cellular repair
Enhances mitochondrial function for optimal energy production
Promotes smoother, more radiant skin through improved cell turnover
Painless, precise, and easy-to-use delivery system with clinical efficacy
Scientific Insight:
NAD+ acts as a master regulator of cellular energy. It fuels enzymes like sirtuins and PARPs key players in longevity, inflammation control, and DNA integrity.
Increasing NAD+ levels has been linked in scientific studies to improved metabolism, neuroprotection, and cellular repair.
Because NAD+ cannot cross the cell membrane easily in oral form, subcutaneous administration via pen injection provides the highest absorption and fastest systemic response
What’s Inside the NAD+ Injection Pen Kit:
- 1 x Premium Auto-Injector Pen
- 2 x Cartridges containing 500mg/3ml of NAD+ each (1,000mg total)
- 1 x Free Travel Case with Cold Cooler Packs
- 20 x Micro-Needles
- 20 x Antibacterial Wipes
- 1 x Sharps Bin (for safe needle disposal)
- 1 x Step-by-Step Instruction Guide
Each 500mg/3ml cartridge provides approximately 10 doses (50mg per injection), totalling 20 doses per kit, lasting around 5 weeks following the standard protocol.
How to use
Storage: Keep cartridges refrigerated upon arrival to preserve stability and potency. The liquid may appear clear or slightly yellow, this is normal.
Dosage: 0.25–0.3ml per dose (50mg NAD+). Each kit includes 20 total doses.
Protocol: Begin with one dose per day for the first three days, then reduce to every other day. Continue for approximately five weeks. Individual needs may vary, some users prefer daily use, while others dose 1–2 times per week for maintenance.
Administration: Using the NAD+ Pen, inject subcutaneously into a fatty tissue area (abdomen, thigh, or upper arm). Rotate injection sites regularly to minimise irritation.
Hygiene: Use a new sterile needle for every injection and clean the area with provided antibacterial wipes. Dispose of used needles in the included sharps bin.

Fuels mitochondrial energy production for sustained, all-day vitality.
Skin renewal
Supports cellular turnover for smoother, more radiant-looking skin.
Mental clarity
Helps sharpen focus, memory and cognitive performance.
Age from within
Powers DNA repair and healthy cellular ageing at the source.
Precision injection pen delivers a controlled, virtually painless subcutaneous injection
1000mg pharmaceutical-grade NAD+ for high-dose replenishment with maximum bioavailability
Pen design simplifies self-administration, no clinical experience required
Supports cellular energy, cognitive clarity and recovery at the mitochondrial level
Includes all components for a complete at-home treatment session

A few quiet minutes, every other day
No clinic, no appointments. Each kit comes with everything you need for a hygienic at-home routine, plus a step-by-step guide. Refrigerate on arrival, rotate sites, and let your cells do the rest.
The science of NAD+
Nicotinamide Adenine Dinucleotide (NAD+) is a vital coenzyme found in every living cell, responsible for driving energy metabolism, DNA repair and cellular communication. As we age, NAD+ levels naturally decline, leading to fatigue, slower recovery and visible signs of ageing.
Replenishing NAD+ reawakens cellular vitality and supports healthy metabolic function. Delivered subcutaneously, it bypasses the digestive system for exceptional absorption, so your cells can begin using it almost immediately.
NAD+ powers the sirtuin and PARP enzymes that regulate cellular repair, inflammation and gene expression. Raising NAD+ availability has been shown to mimic the effects of caloric restriction, extending cellular lifespan and improving metabolic resilience.

Close to 100% bioavailability
Oral supplements are largely broken down in digestion. Delivered subcutaneously, NAD+ reaches your system directly, so cells can start using it straight away for energy and repair.
How to use
Storage: Keep cartridges refrigerated upon arrival to preserve stability and potency. The liquid may appear clear or slightly yellow, this is normal.

Your questions answered
Is NAD+ safe to use at home?
Yes, when used as directed. Each kit is produced in ISO-certified labs, batch-tested for purity, and includes everything for hygienic self-administration plus a step-by-step guide and video. Always speak to your practitioner first if you are pregnant, breastfeeding or managing a health condition.
How soon will I feel a difference?
Many people report increased energy, clarity and focus within the first week. NAD+ works best taken consistently across the full protocol.
How often should I use it?
If it is your first time, use one 0.25ml micro-injection daily for the first three days, then move to every other day. Each vial holds roughly 20 doses.
Why injection instead of a capsule?
Subcutaneous delivery bypasses the digestive system, where much of an oral dose is broken down. That gives NAD+ close to 100% bioavailability, so your cells can use it straight away.
Will the injection hurt?
It can sting slightly and small bruises are not unusual. Take the vial out of the fridge about 30 minutes beforehand, as cold solution stings more. Pinch the skin, insert at a 45 degree angle just under the skin, and rotate sites each time.
Where is best to inject?
The needles are for subcutaneous injection, just under the skin into fatty tissue. The stomach, hips or buttocks all work well. Rotate the site with each dose to minimise irritation.
Who is NAD+ not suitable for?
NAD+ is not suitable for anyone under 18, or with an allergy to NAD+ or sterile solutions. Please avoid it, or speak to your doctor first, if you have or have had: active or previous cancer, pregnancy or breastfeeding, Lyme disease, a recent skin graft, atrial fibrillation, immunosuppression, an organ transplant, or a history of Haemophilus influenzae.
Are there any side effects?
Most people notice none and simply feel alert and energised. Occasionally there can be temporary tiredness for a day or two, or mild sensitivity at the injection site. If that happens, choose a different site next time, and stop if anything feels unusual.
What colour should the solution be?
A transparent liquid that is either colourless or has a light yellow tint. Both are completely normal.
How should I store it, and what is the shelf life?
Refrigerate the vial for optimal freshness. Unopened and stored correctly it keeps its quality for 12 months. NAD+ also stays stable at room temperature for several weeks, so a day in transit is no problem.
How do I dispose of the needles and vial?
Place all used needles and the empty vial into the sharps bin provided, making sure nothing sticks out of the top.
How is this different from an IV drip?
It delivers the same NAD+ benefits with near 100% bioavailability, but on your own schedule and at a fraction of the cost of in-clinic IV therapy. No appointments, no waiting rooms.
How is it delivered?
Discreetly and tracked across the UK, packed with a cool pack to keep it in perfect condition. A Certificate of Analysis is available on request.
