Each value keeps its acquisition path attached. Missing fields are shown rather than inferred. Confidence describes extraction and attribution—not result quality.
Provenance corrected · Oct 9, 2026. We had labelled the testing date on this record “Document extracted”, as if we read it from the certificate. It came from Peptide Tech’s COA listing. It is now labelled “Vendor stated”; the value is unchanged. How we label provenance
PRODUCT RELATIONSHIP
Exact catalog attribution
The vendor and normalized product URL match the tracked catalog exactly. Name-only similarities are never promoted to this state.
Lab-verified and document-extracted panels count as certificate coverage. Vendor-stated panels remain visible, but are not represented as results from this document.

Freedom Diagnostics
This record currently relies on the vendor-hosted certificate and PB’s preserved copy. That is a weaker verification surface than a lab-controlled lookup.
