[Meta] proposal — a flair for vendor posts
proposal — a flair for vendor posts. This affects how posts get sorted and removed, so it belongs in the open. 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. Why the directory has two…
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.
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.

Would qualify this slightly. Fewer entries means less sampling, and less sampling is not the same as a worse process.
Same view. A record you can read beats a rating you cannot inspect, every time.
Careful. "Nobody has tested Core Peptides" is a statement about this board, not about the supplier. Say the first thing, not the second.
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.
buy small first, test it, then decide
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.
consistency across lots beats one spectacular result
This. Ask for the batch record. The ones who send it inside a day have told you more than any review could.
