A high purity number is useful, but it does not answer whether the document actually belongs to the current material or batch.
I built a free browser-based checklist for auditing the documentation trail around a peptide COA and batch record. It scores ten visible items:
It does not certify purity, identity, safety, sterility, suitability, or medical use. It only measures how complete and internally coherent the visible documentation is.
No file upload or account is required. The optional source and batch fields stay in the page, and the result can be copied as a short audit summary.

Disclosure: I built this for LynxLabs, a Canadian research-use-only supplier. I am posting it because the checklist may be useful beyond our own documents, and I want the community to pressure-test it.
What would you add, remove, or separate? I am especially interested in whether sterility, endotoxin, assay/fill, and direct lab verification should become their own second-stage audit instead of being mixed into a documentation-completeness score.
