The verifiability gap: lab reports posted by research peptide stores

Anonymised, record-level audit of 18,810 lab reports (certificates of analysis) posted by 136 research peptide stores, built from the PeptideBenchmark public COA API: whether each report carries a lab-hosted verification link, which lab issued it, its age, and whether it is still posted. Store names are replaced by codes. Updated monthly. Findings, method and the corrections from a 100-report hand check: https://nuuvive.com/studies/verifiability-gap. Built from the PeptideBenchmark public COA API; record IDs, permalinks and provenance labels are preserved as its reuse terms ask. Inclusion of a report is not an endorsement of any product, store or laboratory.
