COA Authenticity Checker

Q: What does the COA Authenticity Checker do?

It fetches the COA URL a vendor cites, confirms the document is still live at that exact address, and scans it for a recognized third-party lab name, batch/lot ID, date, and purity figure — the signals a credible Certificate of Analysis should show.

Q: Does a 'pass' mean the peptide is pure?

No. It means the COA is reachable and carries the structural signals of a real third-party report. It does not re-test the compound. Always read the COA and cross-check the lab independently.

Paste the Certificate of Analysis URL a vendor gave you — or upload the COA as an image or PDF. We check it for a recognized third-party lab, a batch/lot ID, a date, and a purity figure, then run an AI analysis of its completeness and internal consistency. This does not re-test the compound; it analyzes the document, not the molecule.
