Every price on this site was read once, on one day
376 figures from 106 sellers, read September 2026. Written September 2026.
A price index owes a reader the date before it owes them anything else. There is exactly one date on this site: every figure was read on the same day, none has been read a second time, and nothing here can tell you whether a price moved.
One date, on every figure
The premise of this site is that a price is a point in time, so the date is not a footnote here — it is a column on every board and a line on every seller’s page. There is currently one date to print. All 376 figures, from all 106 sellers, were read on September 2026.
That is a smaller claim than a price index usually makes and it is the true one. It also means the two most attractive things a price index can say — that a price went up, or that a price has held — cannot be said here about any seller at all. Sellers in this index with a second reading: 0 of 106.
What a second reading would change
A second reading is not a correction of the first. It is a new reading with a new date: the same 106 sellers’ pages read again, with the same rules, producing a second figure and a second date beside the first. Nothing about the first reading changes, and no figure is ever dated earlier than the day it was read.
What it would unlock is everything this site is named for. A seller’s row could carry what it charged before as well as what it charges now. The 73 standing monthly rates on the dated index could be compared with themselves rather than only with each other. And the sellers who publish a floor and nothing else could be checked for whether their floor is the same floor.
Until then the honest thing is a snapshot with a date on it, which is what this is.
The figures already flagged for reading again
7 figures are flagged in the record as needing to be read again before anything is built on them. The flag is set at reading time and it does not say the figure is wrong; it says the page it came from was doing something that a second look should settle.
| Seller | Figure | The words printed around it |
|---|---|---|
| InstaRX | $265 | “NAD+ Injection Starting at $265/Month *” |
| RNK Health | $139 | “AS LOW AS $139” |
| RNK Health | 139 | “Starting at 139/month” |
| RNK Health | $269 | “$269 from $139” |
| RNK Health | $139 | “$269 from $139” |
| Neo Soma Healthcare | $175.00 | “NAD+ $175.00 every 4 weeks” |
| ShedRx | $144 | “NAD+ Injections for energy support Starting at $144” |
The flag says the record should be read again before it is leaned on. It does not say the figure is wrong, and it is not a date: nothing in this index records when a figure stopped being trustworthy, only when it was read. One of these sellers prints its figure without a dollar sign, and that is transcribed as printed too.
Source: The re-read flag is a field on the record, set at reading time. Each row prints the seller, the figure exactly as the seller wrote it, and the sentence printed around it. Read September 2026.
Every one of them is still published, on the seller’s own review page, with the seller’s own words attached. Hiding a figure because it is awkward would be a different kind of dishonesty from publishing one that is wrong, and it would be invisible.
No schedule is published, because none has been decided
The obvious next sentence for a page like this is “prices are checked monthly”. It is not written here, because nobody has decided that and a schedule that is stated and not kept is a claim that decays quietly: the sentence stays true-looking on the page for as long as nobody checks the dates against it.
What can be said instead is exactly what is on every row: this figure was read on this day. A reader who wants to know whether it still stands can open the seller’s page — the address it was read from is printed as text on every seller’s review — and see for themselves. That is a weaker promise and a checkable one.
What this page cannot tell you
It cannot tell you when a figure stopped being accurate. The flag above marks figures worth re-reading; it is not a date and it is not an expiry. Nothing in this index records when a price changed, because nothing in this index has watched one change.
It also cannot tell you how a seller’s page behaved for you. Several of the sellers here publish different figures on different surfaces of their own site on the same day, and a few gate a figure behind a form. What is recorded is what was on the page that was read, on the day it was read.
Where on the page did a figure sit? This is the basis of the judgement that separates a published figure from one present only in the markup, and it is currently recorded as a yes-or-no rather than as a location.
A reading pass that records the surface each figure was read from — a hero, a plan card, a comparison table, a structured-data block — as a field. The publication judgement would then be checkable rather than merely stated.
When a seller prints two figures side by side with nothing linking them, which one belongs to which? This index can record two figures and cannot record that they are a pair, or that they contradict each other.
A field naming the offer a figure is paired with, recorded at reading time. It is a schema shape rather than a value: no field can hold a disagreement between two other fields, which is why the figures that disagree are currently marked unresolved one by one instead of as the pairs they are.
About this page
Nobody at this site holds a medical license and nothing here is medical advice, diagnosis or treatment. This is a price index; the pages like this one exist because a reader cannot judge a price without knowing what the thing is. Talk to a licensed clinician before starting or stopping anything, and see the medical disclaimer.
Every count above is computed from this index’s own reading of 106 sellers’ pages, described below, and is recomputed each time this page is built — so it cannot drift from the tables and the reviews it is drawn from. If something here is wrong, the corrections page says how that gets fixed and what has been fixed before.
Where these figures come from
Every count on this page is computed, at the moment the page is built, from this index’s own record of what 106 NAD+ sellers publish about their prices: 376 figures in all, 344 of them distinct once 32 repeats of the same offer on a second surface are set aside, and 41 of them present only in a page’s markup rather than visible to a reader. Nothing here is typed into the prose, so a count in a sentence and the same count in a table cannot disagree.
All 376 figures were read on one day, September 2026, and there is no second reading. That is the standing limit on this page and on every page like it: nothing here says a price rose, fell or held, because nothing here has been measured twice. 7 of the 376 carry a flag saying they need reading again before they are relied on, and the reviews of the sellers concerned say which and why.
Each seller has a review page of its own listing every figure this index holds for it — the figure as the seller printed it, what kind of figure it is, the seller’s own words for the billing cycle, the day it was read and the address of the page it was read from. That is the trail from any number on this page back to a sentence a company published.
