Pep TrustPeptide COA verification
Know what's really in the vial
Pep Trust reads a peptide Certificate of Analysis (COA) and tells you, in plain language, how authentic and how complete it is — cross-checking the testing lab, the molecular weights, and known forgery markers.

Why a COA isn't enough on its own
The research-peptide market is largely unregulated, and a Certificate of Analysis is the main objective evidence that what's in the vial matches the label. But COAs can be outdated, generic, reused across products, or outright forged — and most buyers have no way to read one critically. Pep Trust is that second pair of eyes.
How it works
Upload the COA
Drop in a PDF or photo of the certificate. No account needed to start — your first scan is free.
We cross-check it
Dozens of checks run automatically: the testing lab, the claimed molecular weight vs. the real peptide, purity sanity, and visual forgery markers like pasted-over or pixelated fields.
Get a clear verdict
Two scores plus a plain-language breakdown of every red flag — so you understand the result even without a chemistry background.
What you get back
Is this document genuine?
Whether the COA looks real or shows signs of tampering, template reuse, an untraceable lab, or a mismatched molecular weight.
How thorough is the testing?
Which sections a strong COA should contain are actually present — identity, purity, mass, contaminant testing — and which are missing.
Every flagged item is explained in plain English (for example, "Laboratory address is missing" or "Molecular weight doesn't match the named peptide"), so you know exactly what to ask the vendor for.
Frequently asked questions
How can I tell if a peptide COA is fake?
Common red flags include no testing-laboratory name, a layout reused across different products, blurred or pasted-over fields (lab name, batch number, QR code), a molecular weight that doesn't match the named peptide, a suspiciously perfect 100% purity, and no way to verify the report with the lab. Pep Trust checks for all of these automatically and explains what it finds.
What is a Certificate of Analysis (COA) for peptides?
A COA is a lab report stating what a specific batch was tested for and the results — typically identity (by mass spectrometry), purity (by HPLC), and sometimes contaminant testing. It's the main objective evidence that the contents match the label, which matters most in an unregulated market.
What should a legitimate peptide COA include?
At minimum: the product/peptide name, a batch or lot number, the analysis date, the testing laboratory's name and contact details, a numeric purity result, mass-spectrometry identity confirmation, and ideally a way to verify the report with the lab. A thorough COA also includes a chromatogram and contaminant testing. Pep Trust shows you which of these are present and which are missing.
Does a high purity number mean the peptide is safe?
No. Purity is not safety, and it's not potency. A COA usually doesn't test for sterility, bacterial endotoxins, heavy metals, or residual solvents — and a peptide can be highly pure yet degraded or misfolded. A COA also only describes the sample that was tested, not necessarily the vial you received. The only way to know what's in your vial is independent testing of that vial.
Is my first scan really free?
Yes — you can run your first COA scan at no cost and see the full diagnostic before deciding anything.
