NAD⁺ at home: injections, pens and drips compared
Most people meet NAD⁺ in a clinic chair with a cannula in their arm. This is the plain version of what a drip does, what an at-home NAD⁺ injection pen does, what each costs a month, and how to pick a dose.
What an NAD⁺ injection is
NAD⁺ (nicotinamide adenine dinucleotide) is the coenzyme your cells use to turn food into usable energy. Cells spend it constantly and rebuild it constantly, and the rebuilding slows with age, which is why the clinics that offer NAD⁺ tend to fill up with people in their forties and fifties.
An NAD⁺ injection places the molecule in the tissue just under the skin, where it enters the bloodstream without passing through the digestive system. That route is the reason clinics use drips and injections rather than tablets. Our vial contains two ingredients, NAD⁺ and water for injection, made in the UK with no preservatives or buffers.
NAD⁺ drip vs injection at home
| Clinic drip | At-home pen | Capsules | |
|---|---|---|---|
| Routehow it gets in | Into a vein by cannula | Under the skin, pen needle | Swallowed, through the gut |
| Typical costUK, 2026 | £250 to £900 a visit | £175 to £235 a month | £20 to £80 a month |
| Time | One to three hours in a chair | A few minutes | Seconds |
| Where | A clinic, by appointment | Home | Anywhere |
| Cadence | When you can get there and afford it | Monthly plan, dosed through the month | Daily |
| Who does it | A nurse | You, after the first go | You |
The drip is not the problem. Getting there every month is. NAD⁺ is spent, not stored, so one large dose in a clinic rises and falls, and the next appointment is a morning off, a drive into town and another bill. A pen on a plan delivers the same molecule in smaller amounts, more often, at home.
The NAD⁺ pen, and why people call it a peptide pen
The pen format comes from the injector pens used for insulin and peptides, which is why "NAD⁺ peptide pen" turns up in searches. NAD⁺ is not a peptide, it is a coenzyme, but the device is the same idea: a fine, short pen needle, a measured dose, and no vial-and-syringe drawing up.
The DIYNAD⁺ pen ships as a month's supply, 750mg or 1000mg of NAD⁺, taken in small doses across the month following the instructions in the pack. It is on a monthly plan you can pause, skip or cancel, so the cadence looks after itself.
NAD⁺ 500mg, 750mg or 1000mg: which dose?
Clinic drips are usually sold per visit, most often between 250mg and 1000mg in one sitting. A pen is a monthly amount, so the numbers are not like for like: a single 500mg drip is less NAD⁺ over a month than 750mg spread across it, and it arrives all at once rather than steadily.
We make two strengths. 750mg a month is where most people start. 1000mg a month is for people who want the higher amount from the beginning, typically those who have already been having drips, train hard, or are over 55. We do not make a 500mg pen; if you have been offered 500mg as a drip dose, the 750mg pen is the closer equivalent over a month.

The plan prices are £175.00 a month for the 750mg pen, £235.00 for 1000mg and £110.00 for the nasal spray, each delivered every 28 days with free UK delivery. One-off purchases are £205.00, £275.00 and £135.00. The spray is the needle-free option: the same two ingredients, two sprays a day, a month per bottle. It delivers less per dose than the pen, which is why we say so on its own page.
Doing NAD⁺ injections at home
Everything you need comes in the box with written instructions, and the first dose takes longer than any after it. A pen needle is the size used for insulin, a brief pinch rather than a clinic cannula. Rotate the site, store the pen as directed, and keep to the schedule in the pack.

NAD⁺ at home, answered
Does an NAD⁺ injection hurt?
A pen needle is short and very fine, the type used for insulin. Most people describe a brief pinch. It is a different experience from a drip, which needs a cannula placed in a vein and left in for the length of the infusion.
How long does a pen last?
A month. The plan delivers every 28 days so the next one arrives before the current one runs out, and you can pause or skip a delivery from your account.
What is in the vial?
NAD⁺ and water for injection. No preservatives, no buffers, no other actives. It is made in the UK.
Can I switch from clinic drips to the pen?
It is the same molecule by a different route, and a large share of our customers came to us from a clinic. If you are under a clinic's care for a condition, tell them you are switching.
Pen or nasal spray?
The pen puts NAD⁺ under the skin and into the blood; the spray is needle-free and delivers less per dose. If you will not inject, start with the spray. If you will, start with the pen.
What does "NAD⁺ at home" actually mean?
NAD⁺ you take yourself rather than at an appointment: an injection pen or a nasal spray, delivered to your door on a plan. Ours ships from the UK, monthly, with free delivery.
