the Medutest question that gets asked weekly, answered properly

Resolved Long Haul ×5 The Quiet One ×3

the Medutest question that gets asked weekly, answered properly. Making the case below, and I expect to lose some of it in the comments.

Independent testing is worth more than a supplied certificate for one structural reason: the chain of custody. A member who buys, ships and pays is testing the same thing you would receive.

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.

Happy to answer the boring questions. Those are usually the ones worth asking.

Removed pending evidence. Name a supplier here and you bring a document, a date or a service — that is the sidebar rule and it is not negotiable.

Lead time and minimum quantity are the two facts people forget to ask for and then argue about later. Both are answerable in one email before you commit.

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.
