Why ten checks?
A purity percentage is not a batch trail.
A useful source record connects the exact product, lot, report, method, identity evidence, label, and receiving file.

Check a peptide COA in ten points.
Score the visible documentation trail before trusting a purity number. Match the compound, batch, lab, method, identity evidence, fill, storage record, and claim boundaries, then copy a clean audit summary.

What this catches
Generic or mismatched COAs.
The checker surfaces missing batch IDs, stale dates, unnamed labs, bare purity claims, and gaps between the report and product page.
What it does not do
It does not certify material.
The score is a documentation screen, not independent testing, legal advice, a safety verdict, or a medical-use recommendation.
