Peptide certificate of analysis: three checks that make it real
A federal case over forged lab certificates shows how much weight a certificate of analysis carries. Three checks separate a real lab report from a marketing PDF.
A peptide vendor was recently sentenced to 70 months in federal prison for selling research chemicals alongside forged laboratory certificates. It is one of the first major criminal prosecutions in the research-peptide space, and a clear reminder of how much weight a certificate of analysis carries.
A COA is a lab report, not a marketing PDF
A real certificate of analysis is a batch-specific laboratory report. Over the past year, independent testing labs have flagged cases where a vendor's stated purity and its actual lab results did not line up. In a market with this little oversight, the certificate does the job that regulation would otherwise do.
Three things a legitimate COA shows
Batch-specific results
Purity and identity results vary from batch to batch because of the nature of peptide synthesis. A generic template reused across every product listing is not a test result. A COA whose numbers never change across batches is not measuring anything.
An identifiable, accredited third-party lab
Independent verification is the entire point of third-party testing. An in-house or unnamed source cannot be checked, and a lab that cannot be looked up defeats the purpose of having a COA at all.
A lot number that matches the vial
The lot number on the certificate should match the lot number on the vial in hand. Without that match, there is no way to confirm that the document corresponds to the material being tested.
Read the COA as a research variable
Every downstream result depends on the identity and purity of the starting material. That makes the certificate part of the experimental record rather than paperwork to skim past. Reading it with the same care as a methods section is the most direct protection against a forged or recycled report.
