You want to know what NAD⁺ costs. You open a seller’s site, look for a number, and find a button that says get started.
Of the 166 sellers we have reviewed, 129 publish a price you can read before committing to anything. 37 do not. On those, the only route to a figure runs through an intake.
That is a bigger share than it sounds, because it is not spread evenly: it is concentrated among clinics and the IV services, where per-session pricing is the norm.
What an intake actually asks
The shape is consistent: an online questionnaire, then review by a licensed provider, then — if approved — a price and a shipment. Some add a required blood panel before anyone will prescribe, which is better medicine and a longer wait.
The questionnaire is a medical history. Conditions, medications, sometimes a photo ID. None of that is unreasonable for a prescription product. It is simply a lot to hand over to learn a number that could have been printed on the page.
The three things it costs you
Comparison. This is the real one. You cannot open four sellers, look at four prices and pick one, if three of them require a medical history first. The practical effect is that you compare the sellers who publish and take the rest on trust, or you commit fifteen minutes each before you know anything.
An asymmetry. By the time you see the number, they know your medical history and you know one price. You have also usually invested enough effort that walking away feels wasteful, which is the part the design is doing work on.
A marketing relationship. Your email address is now in a system. That is a fair trade for a service you wanted and a poor one for a price check.
Where it is defensible
Sometimes there genuinely is no single number. A clinic pricing per visit, or a service setting the dose from bloodwork, cannot quote before it knows what it is quoting for. One concierge-style provider prices the in-office route per visit and the home route separately, which is a real reason rather than a tactic.
Even then, a range would work. “Most patients pay between X and Y” costs the seller nothing and answers the question. The sellers who publish nothing at all are not usually the ones with the most complicated pricing.
How to decide without starting one
- Start from the sellers who publish. Our price table holds every figure we have verified, and the cheapest options are ranked on the rate that repeats.
- Use those to build a range. If most verified injection prices sit in a band, a seller refusing to quote is unlikely to be far outside it — and if they are, it is more often above.
- Check the review before the intake. Where we found a figure on a call or a checkout, we recorded it.
- If you do start one, note what you were told at the end and compare it against what the advertised figure usually turns out to mean.
The one that publishes nothing at all
One seller we cover has no pricing page, no price on either product page, and no dollar figure anywhere on the site — we opened every page it publishes to check. Its product pages are otherwise careful and restrained, which makes the omission more striking rather than less.
In a category where verified prices run from roughly $60 a month to more than $700 a session, withholding the number is not a neutral choice. It moves the whole comparison onto the seller’s ground.
None of this makes a seller bad. It makes them harder to check, and the reviews say which ones they are.
