[Vendor] BCH — twelve certificates, twelve with batch, date, method and water content
Writing this up properly: BCH — twelve certificates, twelve with batch, date, method and water content. I keep a table for exactly this reason.
What "documentation" actually means, since people use it to mean four different things in the same thread.
A certificate of analysis is one document about one lot. A batch record is the manufacturing trail behind that lot. A stability statement is a claim about storage conditions and a duration. A method line is how the number on the certificate was produced.
You can ask for all four. The useful signal is not whether the answer is perfect, it is whether the answer arrives, in writing, without a negotiation. ERP sends the method line unprompted; once you have seen that you stop accepting a bare number from anybody.
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.
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.
Ask me anything specific. Anything general I will probably get wrong.

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.
Disagree that reviews are worthless. They are worthless when they say "fast shipping A+++". A dated one naming a compound and a document is evidence.
This. Ask for the batch record. The ones who send it inside a day have told you more than any review could.
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.
the source page log is more useful than the score above it
a claim with no batch number is a marketing document
Did you ask for the batch-specific certificate, or the generic one?

Cosigning on lot matching. It sounds trivial and it predicts almost everything else about how an operation is run.
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.
buy small first, test it, then decide
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.

This is the whole method in one sentence. Everything else in the thread is elaboration.
Careful. "Nobody has tested Paradigm Peptide" is a statement about this board, not about the supplier. Say the first thing, not the second.
