The page and a half you were emailed, read as a document
The same word, in research, names a document that has to exist before a single participant is approached, that is registered publicly, and that its authors are then held to. Understanding the difference between those two objects is most of what a person needs to evaluate the one in their inbox.
Set aside for a moment whether the plan is a good idea and ask a narrower question: what does this document oblige anyone to do?
It commits you to a series of appointments and to paying for them. It commits the provider to supplying those appointments. It does not commit anyone to a definition of success, to a point at which the plan is abandoned, to recording what happens, or to telling anybody the result. If you finish the course and feel exactly as you did before, nothing in the document has been contradicted, because nothing in it made a prediction.
That is not a hidden flaw. It is what the genre is. A service schedule is a perfectly honest thing for a business to produce. The problem starts when it is read as though it belonged to the other genre.
Why an NAD+ protocol binds nobody to anything
The features that give a research protocol its authority are all absent, and each absence is worth naming rather than gesturing at.
There is no comparison group, so any change you notice has nothing to be compared against except your own memory. There is no blinding, so both you and the person charging you know what you received. There is no outcome named before you started, so the result can be judged afterwards against whatever ended up looking best. There is no registration, so no external record exists of what was planned. There is no analysis plan, no independent monitoring, no ethics review of the risk you are taking, and no obligation to publish anything at all.
Remove all of that and what is left is a plan of purchases. It may still be a plan you want. It carries no evidential weight, and it cannot generate any.
The two documents, obligation by obligation
The last row is the one people notice least and it changes the incentives of every row above it.
| Obligation | Registered trial protocol | Plan emailed by a provider |
|---|---|---|
| Written before anyone is exposed | Required | Written after the consultation |
| Publicly registered | Required in the systems that matter | No |
| Primary outcome named in advance | Required | Absent |
| Comparison group | Specified, usually placebo controlled | None |
| Reviewed by an ethics committee | Required | No |
| Independent safety monitoring | Usual for anything invasive | The practice monitors itself |
| Results reported whichever way they fall | Expected, and increasingly enforced | Nothing is reported |
| Who bears the cost | The sponsor | You |
The loading course, and the arithmetic underneath it
Almost every plan in this market opens with a run of closely spaced sessions before settling into something slower. The shape is borrowed from real pharmacology, where a loading phase exists because a drug with a known half life takes a predictable time to reach a steady concentration, and the loading amount is calculated from that.
Here the borrowing keeps the shape and drops the calculation. For the injected coenzyme in humans there is no published work establishing what is reached, how long it persists, or what would count as steady. The interval was not derived. It was chosen, and it happens to front load the revenue of the course.
That may be uncharitable in an individual case. Some providers space sessions closely because clients report feeling better that way, which is a reason, if not a strong one. It is not a reason drawn from the compound's behaviour in people, because that information has not been generated.
What happens when you report back that nothing changed
Watch what the document does with a negative result, because this is where the difference from a trial becomes concrete rather than theoretical.
You finish the loading course and feel no different. In a trial, that outcome was defined before you enrolled, it goes into the analysis, and it counts against the intervention whether anyone likes it or not. There is no version of the study in which your result is quietly reinterpreted.
In a clinic, the same report has several available answers and none of them is written down in advance. You may be told that the loading phase needs extending. That responses vary and yours is slower. That a maintenance schedule is where the benefit accumulates. That your baseline was lower than expected. Every one of these can be said sincerely by a clinician who believes it, and every one of them converts a disconfirming result into a reason to continue.
That structure is what philosophers of science mean by a claim that cannot fail. It is not evidence of bad faith. It is a property of a document with no prespecified outcome, and it will behave this way even in the hands of the most scrupulous provider.
The practical test is worth applying before you start rather than after. Ask, at the first appointment, what result after the loading course would make them recommend stopping. A provider who has an answer, and who names something specific and checkable, has given you a version of prespecification that the document itself does not contain. A provider whose answer is that a lack of response means more sessions has told you the plan cannot be wrong.
The part of the bill that buys something real
None of this makes a clinic worthless, and pretending otherwise would be its own kind of dishonesty.
What you are buying that has value: a trained person taking a history, who may spot that your tiredness has a cause worth investigating properly. Someone who checks your medication list. Sterile technique and a cannula placed by somebody who does it regularly. A room with a person in it who will notice if you react badly and stop. Insurance, and a complaints route that leads somewhere.
What the fee cannot buy, at any price: an approved use, a verified product, a defined amount, a leaflet listing known harms, a recall mechanism, or a reporting system that will record your experience so that the next person benefits from it. Those are functions of a regulatory system, not services a practice can generate.
A provider who tells you which column each part of their offer sits in is being straight with you. That is a better signal than anything in the document itself.
