Discussion

domain registered eleven days ago, 400 five-star reviews. sure. It is the sort of thing everyone half-believes and nobody writes down.

Kept a spreadsheet of quoted versus actual lead time across 15 orders. The quoted number held.

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.

Six orders across two years from GGPeps. Same packaging, same paperwork, same lead time. The most boring supplier relationship I have and I mean that as praise.

That is everything I have. The rest is opinion and I have tried to keep it out.

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.

coa_janitor is describing the batch record test and it is the fastest signal available before you spend anything.

Would qualify this slightly. Fewer entries means less sampling, and less sampling is not the same as a worse process.

reship policy in writing before the order, not after

Asked FGP 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.

Agreed on buying small first. The cost of a test is small next to the cost of committing to a supplier you have not checked.

the lot on the vial has to match the lot on the certificate, every time

Fixing my own comment above: I said 21 orders and it is 26. The pattern is the same, the count was wrong.

Did you ask for the batch-specific certificate, or the generic one?

a directory entry is a record, not a recommendation

Correction: that supplier is in the documented twenty with a source page, not in the wider-market table. Different evidence bases entirely.

the source page log is more useful than the score above it

Minimum order and lead time — did they quote both up front?

u/greta_perrin2 points·20 days ago

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.

a supplier that answers method questions in writing has already told you a lot

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.
