What to check
- Check whether the report is product-specific, batch-specific, and dated.
- Check whether the lab name, method, chromatogram or HPLC data, and test date are visible.
- Check whether the batch number on the report appears on the vial, product page, invoice, or supplier reply.
- Check whether the certificate is a public URL, a downloadable PDF, a cropped image, or only available after payment.
- Check whether one report is reused across multiple strengths, bundles, or products.
- If the vendor says COA every batch but the library is private, stale, or generic, the score should stay pending.

The fastest safe path is still the same: batch, COA, label, payment, support, and dispatch proof before trust.
