the VendorInvestigate thing finally clicked for me and I want to write it down

Needs Source Receipts ×1 Cold Box ×2 Sourced ×3

the VendorInvestigate thing finally clicked for me and I want to write it down — a position I have arrived at slowly and would like tested.

Why the directory has two tiers, since the question comes up whenever somebody new finds it.

Twenty suppliers have enough independent results, over enough separate lots, over enough time, that the log says something. Those get a page, a test table and a link to their own storefront so you can compare their claims with the record.

The rest — nearly two hundred names — get a row, a band and a report count. Not because they are bad, but because two results is an anecdote about a vial. Manufacturing a score out of that would make the whole directory worthless, and the contrast is the point.

A certificate with a purity figure and no method line is not falsifiable. You cannot reproduce it, you cannot check it, and it tells you nothing about how the number was produced.

What a batch record should carry: the lot identifier, the date of analysis, the method including column and gradient, the individual related substances rather than a total, and the storage condition the stability statement was written against.

Ask me anything specific. Anything general I will probably get wrong.

best — the order this archive was captured in

Where a supplier holds regional stock, ask which lines are actually held there rather than drop-shipped. It changes the lead time and it changes the customs question.

Fixing my own comment above: I said 21 orders and it is 8. The pattern is the same, the count was wrong.

This is the whole method in one sentence. Everything else in the thread is elaboration.

registration number, then everything else

Cosigning on lot matching. It sounds trivial and it predicts almost everything else about how an operation is run.

That is a report count, not a test count. The table lists both and they are very different numbers.

About c/vendorvetting

The community due-diligence desk. Vendor experiences, independent third-party test results, shipping and reship records, and the boring paperwork that separates a supplier from a story. Every substantive claim is expected to carry a receipt: an order id, a dated screenshot, or a test report from Janoshik, Medutest, PeptideMeter or VendorInvestigate.
