The nine flags
These are unordered. A warning near the bottom is not weaker than one near the top; each is a separate thing to look for, and each is settled by a question about a document rather than a feeling about a brand. No seller is named on this page.
The page has an incentive and does not say so
Any page telling you where to buy stands to gain from where you go, this one included. The honest ones put that in writing above the first outbound link, not only in the footer where it is easy to miss. An undisclosed incentive does not make the paperwork wrong, but it tells you to read the paperwork twice.
Is there a disclosure, and does it sit above the first link or only at the very bottom?A purity figure with nothing beside it
A number on its own says a laboratory was involved and nothing more. Purity is a measurement, and a measurement carries the method that produced it and the criterion it was judged against. Stripped of both, a percentage is decoration.
Does the figure name its method, and is a release criterion printed next to it?A badge that no file stands behind
The words lab tested set beside a shield graphic are the cheapest thing on any listing to produce. The test is the file, not the badge, and a badge that clicks through to nothing is an assertion dressed as evidence.
Does the badge open a certificate, or does it open nothing at all?A picture of a certificate, not a certificate
An image carries only what sat in the frame when the picture was taken, cropped to flatter. A document has pages you can turn, a certificate number, a batch code, a laboratory name and a date. The difference between the two is the difference between a claim and a record.
Are there pages, a number, a batch code and a laboratory name, or just an image?A certificate that names no laboratory
A panel that will not say who ran it proves nothing about who ran it. The name has to be on the document itself; a laboratory named only in the marketing copy wrapped around the file is a name attached to nothing.
Is a laboratory named on the file, or only in the sentences around it?A panel missing the sterility or the endotoxin line
A purity figure answers one question about a preparation. Sterility and bacterial endotoxin answer others, and on a full panel they sit together on one line. A page that shows purity and goes quiet on those two is showing you part of the panel and calling it the whole.
Are sterility and bacterial endotoxin both present, or is one of them missing?No route from the vial back to the paper
A certificate proves something about a batch. It proves nothing about the unit in your hand unless a published route connects the two. A listing that shows a document but cannot say how a delivered vial ties back to it has skipped the step that makes the document mean anything.
Is there a published way to connect a delivered unit to the certificate shown?A best place claim with no paper behind it
The phrase best place to buy is a marketing line, not a finding, and nothing on the listing is obliged to stand behind it. A verdict with no document under it is ranking itself. A page worth reading points at paper anyone can open instead.
Does the page cite a document you can open, or does it only rank itself?A certificate held behind your email
The certificate is the one thing on a listing that should open freely. When it is held back until you hand over an address, the form has been placed in front of the file on purpose, and the reason is rarely in your favour.
Does the file open without a form, or does the form come before the file?The request that settles most of these
Seven of the nine are answered by one move: ask for the certificate and count what is on it. The request in full, ten lines long, is the request that settles most of these. With it in hand, go back to the audit table and see which counters can produce the document at all.
Scope and research reading
A paperwork note, in short. This page reports two things only: what a seller already publishes for anyone to open without an email, and what one supplier's certificate for this compound records. Material of this kind is sold for laboratory research and it is not an approved medicine. Nothing here says what the compound does, reads the research on it, or weighs a purchase against anybody's circumstances, and a question about a person belongs with a licensed clinician.
