What this certificate reports
Each value keeps its acquisition path attached. Missing fields are shown rather than inferred. Confidence describes extraction and attribution—not result quality.

Provenance key Lab verifiedDocument extractedVendor statedManual review
Provenance corrected · Oct 9, 2026. We had labelled the testing date and purity on this record “Document extracted”, as if we read them from the certificate. The testing date came from Peptide Tech’s COA listing. The purity came from our collection for Peptide Tech, which reads the certificate first and falls back to Peptide Tech’s COA listing without recording which one supplied the value, so we cannot show it was read from the certificate. They are now labelled “Vendor stated”; the values are 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.

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.

05 / CHANGE HISTORY
Versions, changes, and reuse
The archive tracks source and content fingerprints over time, including replacements and certificates that later disappear from vendor sites.
This is the first observed version for this vendor product.
No preceding version is available for comparison.
