A NAD+ injection sold online is a vial of NAD+ and a box of syringes, shipped on a subscription by a telehealth company. It is not the drip you sit through in a clinic, and on this roster the two are priced on completely different terms: most of the sellers here publish a figure for the injection, and only a minority of those ever say how many milligrams you are getting.
What you are actually buying
The word covers two products that share nothing except a molecule. One is an intravenous infusion given in a clinic, billed per session, with a nurse in the room. The other is a subcutaneous vial you receive in the post after an online consult, and it is what almost every search result for “NAD+ injection” is selling. The price comparison between the two has its own page: a per-session price and a per-month price are not comparable until the milligrams and the cycle are attached to both.
What arrives is the drug, the packaging around it, and a prescription. What a seller charges for is usually a bundle: the vial, the supplies, the online consult that produced the prescription, and shipping. On this roster 90 of the 159 injection figures say in the seller’s own words what the number covers, and the rest do not say at all. That gap is the single most expensive thing to guess about, because two figures that look like the same price can be buying a different list.
Some of what is sold beside it is not NAD+. An NMN or NR capsule is a precursor the body converts: a different molecule with its own evidence, not a cheaper version of the same thing. This site marks every one of those rows, and the page on oral NAD+ and precursors is about telling them apart on a seller’s page.
How sellers price it
Not by the injection. Almost nobody prices this per vial: the standard is a subscription, and the question is which subscription. Of the 60 sellers with an injection row, 27 publish a standing monthly rate, meaning a number that will still be the number in month four. The rest publish something else, and the something else matters.
| Charged per | Figures | What that means on the page |
|---|---|---|
| A month | 70 | billed by the calendar month |
| A block of months | 39 | three, six or twelve months, usually paid up front |
| A first period only | 8 | an opening price that is not what you pay next |
| Weeks or days | 10 | every four weeks, every 28 days, per 30-day supply |
| A vial or a unit | 3 | one thing, once |
| No cycle at all | 27 | a number with nothing attached saying how often it lands |
| Two cadences at once | 2 | the page gave a cadence that argued with itself, and the reading refused to pick one |
60 sellers’ own pages, read September 2026. One row per distinct figure, so a seller publishing three prices appears three times. The basis is the one the seller stated; none was inferred from a page title or a URL.
Underneath the cadence sits a second question, which is what kind of number it is at all. Of those 159 figures, 26 are a floor rather than a rate — a “from” price, usually attached to the smallest size or the longest commitment. 13 are an opening price that changes later. 22 are the total for a block bought up front, which divides into a flattering monthly number that nobody is actually charged. 30 could not be resolved into a price anyone pays, and they are kept with that said rather than dropped. And 16 of them are in the seller’s markup without ever being shown to a reader, which is not a published price at all.
Nothing in that table names a cheapest, and the reason is arithmetic rather than manners. A monthly rate, a prepaid block and a floor are three different claims, and only 20 of 60 sellers publish the milligrams that would let you put any two of them on one denominator.
What has been measured in people
Very little, and it is worth being exact about which part. NAD+ given into a vein has been followed in people: a pilot study measured plasma and urine through a six-hour infusion and found no change in circulating NAD+ or its metabolites for the first two hours, with the compound cleared from plasma over that window and appearing in urine by six hours. Its own abstract states that no data on the fate of directly infused NAD+ in people existed before it.1
That is the intravenous route. The subcutaneous injection, the one with 60 sellers behind it, has no comparable human study that a search turns up. A PubMed title search for NAD+ with injection or subcutaneous returns 11 records, and not one of them is a study of subcutaneous NAD+ given to people.
PubMed, searched September 2026. The query ("NAD+"[Title] OR "NAD"[Title] OR "nicotinamide adenine dinucleotide"[Title]) AND ("subcutaneous"[Title] OR "injection"[Title] OR "injections"[Title]) returned 11 records. Every hit was opened. Not one is a study of subcutaneous NAD+ given to people: they are adipose-tissue transcriptomics, flow-injection biosensor chemistry, capsaicin injections in rats, an NMN bolus in animals, and four papers from 1963-1991. A count is what one search returned on one day, not proof that nothing exists anywhere.
So the honest position is that the sellers are ahead of the evidence. That is a statement about what has been published, not an accusation: plenty of things people buy have thin literature behind them. What it does mean is that any page telling you what a NAD+ injection will do for you is telling you something no published human study of that route has measured. Questions about whether it is appropriate for you belong with a licensed clinician, and the page on injection side effects is about which of those questions change with the route.
What to check before you pay
- Milligrams, as a number. Not “a full dose,” not a concentration on its own. Of the 60 sellers here, 40 never print one, and without it no price can be compared with any other price.
- What the figure is charged per, in the seller’s own words, before checkout. A month and a prepaid quarter look identical in the same typeface.
- Whether it is a rate or a floor. “From $X” is not a price; it is the cheapest corner of a price list.
- What is included, specifically the consult, the supplies and the shipping. 69 of 159 figures on this roster do not say.
- What happens in month two. An opening price and a standing rate are different numbers, and 33 of 60 sellers here publish no standing monthly rate at all.
- Who you call, and when that line is open. Nobody is in the room with an at-home product, and the answer to that question is a real difference between two sellers charging the same amount.
Every one of those is answerable from a seller’s own page in about two minutes, and this site’s board of NAD+ injection sellers prints the route, the milligrams and the billing cycle for each row so the answers sit side by side.
To see how the care arrangement is described by an injection provider, read our Mondae NAD+ review. It covers the consultation and patient-portal access the company advertises, plus the pharmacy and checkout details to confirm before signing up.
Every figure above is a seller’s own published number, with the route it buys, the milligrams it buys and the date it was read attached. None of it is medical advice, and nothing here is a recommendation to take or avoid anything. Talk to a licensed clinician who has your history in front of them.
