Test Results

Every result below comes from an independent third-party laboratory. The table is the whole of it — compound, dose, which laboratory ran it, who commissioned it, when, the purity figure, and whatever else that certificate measured. Nothing is rounded, and nothing is carried across from one certificate to another.

Read this before you read the table

We are a distributor and we do not own a laboratory. We are not the client on any report below — every one was paid for by somebody else, and the Source column says which kind. That is worth spelling out rather than letting the word “tested” do the work.

Group test. Our material is bought in shared group purchases, and a panel from that batch is sent to a laboratory by one of the purchasers. We publish what comes back. We are not the client on these reports— someone else in the group paid for them and we do not name them — and the run is not tied to a production lot.

From our supplier. The manufacturer commissioned these from the laboratory, not us. The laboratory is independent of both of us; the sample was not. We did not choose the vial, we did not submit it, and we cannot show you what happened in between. It is the manufacturer’s evidence about their own production — worth publishing, and the weakest of the two kinds here, because the party with the most to gain from the result chose the sample. We would rather show it and say what it is.

Neither kind is lot-verifiable. Neither traces back to the specific vial in your order. Anyone who tells you a published certificate proves what is in the vial you received is claiming more than this kind of testing can do.

Per-lot verification is where we want to be, and we are working toward it.

The underlying test reports behind every row are available on request — email us and we will send them. On a supplier-commissioned report we remove the manufacturer’s name and its internal batch and job numbers first: who makes our material is not something we publish, and a batch number beside a result invites you to believe your vial came from it — the one thing this page tells you no certificate here can show.

Results

A dash means the certificate does not report that field. We would rather leave a cell blank than fill it from somewhere else. Purity is printed exactly as it appears on the certificate. Where a compound appears more than once, it was tested more than once — sometimes by a different laboratory. Where a laboratory prints only a report date rather than an analysis date, the cell says so. The Source column is provenance, not quality — it says who sent the sample to the laboratory, nothing more.

What these laboratories measured

Not every certificate runs every test, which is why the last column is per-row rather than a blanket list. Across the reports above you will find:

• Purity — each certificate states its own measured figure. Where a certificate names the method it used, that is the method; several state a purity result without naming one, and we do not supply the method for them.
• Content and quantity — how much material is actually in the vial, in milligrams, and for blends how that mass splits across components.
• Identity confirmation by LC-MS — on the certificates that carry it.
• Endotoxin and sterility — only where a certificate actually ran them, and reported as the certificate reports them.

Our Guarantee

Our stated purity specification is 98%. If any product does not meet it, we will replace it or issue a full refund. Every purity figure in the table above clears that number. None of these certificates is ours — the supplier-commissioned ones are the manufacturer’s evidence about their own material, and the rest were paid for by other purchasers in the same group buy. The refund promise does not depend on any of that: it is ours either way, and we stand behind every product we sell.
