What should I make of an orforglipron documentation package that has no batch certificate?

Stated plainly: orforglipron · batch certificate.

I would like help reading this properly rather than being told what conclusion to reach.

I have the full report including the method section, so I can quote specifics if that helps.

What would I need in addition before this supported a decision?

The most common trap is reading a certificate as if it were a guarantee when it is actually a single point estimate from a single test.

Writing the lot number on your vial in permanent marker is worth doing because it later proves that the certificate traces to your material.

The test date matters because a certificate six months older than the vial is not evidence about your material, it is evidence about what the material was like half a year ago.

The practical summary: check the lot number, ask for the method, and reserve judgement until you have both.

Before anything else, check that the lot number on the certificate matches the vial in your hand — that traces back to your material and not to some other lot from some other date.

A purity figure to two decimal places with no supporting chromatogram is giving false precision and is a red flag on the same level as spelling errors.

The certificate is a snapshot and nothing else — it tells you about the material on one day from one sample of one lot, and extrapolation beyond that requires logic.

The limitation is cost — truly rigorous testing on every lot is expensive enough that most people do not do it, which is exactly why the variation matters.

If the certificate does not trace to your vial, it is not evidence about your vial.
