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

the answer for the UK does not apply anywhere else

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

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.

Disagree — that is the position in one country and this thread is about another.

Disagreeing with this line: that is the position in a different country and it does not transfer.

a claim with no batch number is a marketing document

A certificate with a purity figure and no method line is not falsifiable.

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

three independent results beat thirty forum posts

Agree. The verification log is the part with the checkable facts in it; the number at the top is just a summary of a lot of averaging.

Mild pushback: a supplier with fewer entries is not worse, it is less sampled. Those are different claims and the table says so.

a claim with no batch number is a marketing document

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

the interesting column is spread, not maximum

Kept every document including the dull ones. When a process started, having the dates in order made it short.

consistency across lots beats one spectacular result

Is this a hold, a request for information, or a seizure notice?

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.

Right — GL Biochem publishes the method line on the certificate, and once you have seen one that does you notice every one that does not.

Not convinced by the ranking-by-vibe approach here. The community number is derived from reports; your feeling is derived from four posts you remember.

Started buying small deliberately, tested every lot for the first four, then stopped testing every lot because there was nothing to find.

reship policy in writing before the order, not after

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.
