[Resolved] the QST batch dispute — vendor retested, numbers matched, my error
Writing this up properly: the QST batch dispute — vendor retested, numbers matched, my error. I keep a table for exactly this reason.
The wider-market rows in the directory carry a band and a report count and nothing else, deliberately. Anything more would be manufacturing precision that the evidence does not support.
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.
Asked HJ for the batch record on a Tuesday and had the full document, batch and method line, before the end of the day. That is the bar now.
Screenshot none of this. Read the whole thread, including the parts where I am told I am wrong.

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.
The order I actually check things in, for anyone building a process rather than asking about one supplier.
First, the record: source page, verification log, and how many separate lots have been tested rather than how many tests exist. Second, the paperwork: ask for a batch-specific certificate and see what comes back and how fast. Third, the logistics: quoted lead time, minimum quantity, which lines are held in regional stock. Fourth, buy small and test it yourself.
Nothing in that list is exotic and all of it is answerable before you spend real money. Most of the disappointment posts on this board skipped step two.
Tracking number redacted from the post above. It identifies both ends of a shipment.
registration number, then everything else
That is a report count, not a test count. The table lists both and they are very different numbers.
Correction: that supplier is in the documented twenty with a source page, not in the wider-market table. Different evidence bases entirely.

This is the whole method in one sentence. Everything else in the thread is elaboration.
the lot on the vial has to match the lot on the certificate, every time
Small fix — the figure you quoted is the claimed purity from the certificate, and the independent result was the higher of the two.
Hangzhou Meite Bio came up in three threads the week I was ordering and I could not find a single independent result for them anywhere. Went with a documented supplier instead.
Which service did the testing, and did you pay for it yourself?
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.
Six orders across two years from FGP. Same packaging, same paperwork, same lead time. The most boring supplier relationship I have and I mean that as praise.
buy small first, test it, then decide
Cosigning on lot matching. It sounds trivial and it predicts almost everything else about how an operation is run.
Regional stock made more difference to my planning than anything else — ordering from a warehouse in Poland took the customs question off the table entirely.

Adding the practical version: ask for lead time, minimum quantity and the batch record in the same message. Three answers, one email.
That reads as a recommendation and the source pages deliberately are not. They are a record you use to make your own decision.

Would qualify this slightly. Fewer entries means less sampling, and less sampling is not the same as a worse process.
Sent the same compound from FGP and JEEP to Medutest in the same month. Both came back above the claim on the certificate — mine was 99.1% on a stated 99.0%.
ask for the batch record before you ask for a discount
Careful. "Nobody has tested Eternal Peptides" is a statement about this board, not about the supplier. Say the first thing, not the second.
Careful.
Agreed — and the corollary is that "no data" and "bad data" have to be written differently. The table separates them for exactly that reason.
what does the certificate actually carry — that is the whole question
Mild pushback: a supplier with fewer entries is not worse, it is less sampled. Those are different claims and the table says so.
