Is this peptide COA real?

Check a Certificate of Analysis for the red flags of a fake, recycled or self-tested COA — free and independent.

This tool gives an automated heuristic verdict for guidance only and is not a lab analysis. Always verify a COA with the issuing lab.

What is a COA?

A Certificate of Analysis is a lab’s signed result for a specific batch — purity, identity and content. Trust depends on whether it’s independently verifiable, not vendor-hosted.

How to verify a peptide COA

  1. 1Find the issuing lab and the report or batch ID on the COA.
  2. 2Look it up on the lab’s public verifier (e.g. verify.janoshik.com) — fabricated COAs fail the lookup.
  3. 3Confirm the batch or lot number matches the product, and that both HPLC purity and mass-spec identity are present.
  4. 4Be wary of vendor-hosted PDFs with no independent verification path or an implausibly perfect purity.

Red flags of a fake or recycled COA

  • Tested by the vendor itself, not an independent accredited lab.
  • No batch or lot number — so the COA can’t be tied to the product you received.
  • The same COA re-used across batches or stores (recycled or shared).
  • A purity figure that looks implausibly perfect (e.g. exactly 100%).
  • HPLC purity only, with no mass-spec identity test to confirm the molecule.
  • No way to verify it independently — e.g. no public report ID or lab lookup.
