On the subject in the title: A supplier who responds to a discrepancy with silence Working notes rather than a conclusion.

Structured report rather than an opinion, following the format the maintainers asked for.

Compound: semaglutide
Independent testing: VendorInvestigate
Method as reported: reversed-phase HPLC, 280 nm
Result: 98.1% area
Certificate figure for the same lot: 99.1%

I am not drawing a conclusion about the supplier from one lot and I would ask that nobody else does either. I am adding a data point to a record.

Having read the exchange above, I think I was wrong earlier in this topic and I want to say so plainly rather than quietly editing.

The correction was fair and I had been repeating something I had not checked carefully enough.

Documentation quality as a signal: a supplier that reports method identifiers, distinguishes specification from result, and states the counter-ion form is telling you something about systems behind the document. A certificate that is a number and a signature tells you less.
