[Vendor] CPC — 2001 establishment date checks out against the company registry

Vendor Receipts ×3 Cold Box ×1

Adding to the record: CPC — 2001 establishment date checks out against the company registry. It matches what the source page already shows, for whatever that is worth.

Inter-lab variance on this assay runs a point or two either way. Two services disagreeing by that much is agreement, not a discrepancy, and treating it otherwise starts pointless arguments.

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.

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.

Corrections welcome, especially the pedantic ones. Pedantry is how this board earns its reputation.

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.

Sent the same compound from KP and HJ to Janoshik in the same month. Both came back above the claim on the certificate — mine was 97.7% on a stated 97.0%.

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

The thing that decided it for me was that BCH answered a column-and-gradient question in writing without asking why I wanted to know.

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.

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.
