Is your peptide source telling you the truth?
Answer eight questions about the vendor and the lab report in front of you. You get a verdict, the specific weak points, and the exact next step to confirm the material with the laboratory itself. Everything runs in your browser — nothing you enter leaves this page.
1. Can you see a Certificate of Analysis before you pay — without asking?
“COA on request” is the oldest stall in the market. Real documentation is published, not promised.
2. Does the report name the independent lab that ran it?
A named third-party lab (Janoshik, Freedom Diagnostics, etc.) can be contacted. “Tested in-house” is not third-party testing.
3. Does the COA carry a lot or batch number that matches your vial?
A report is only evidence for the exact batch it tested. An unmatched report tells you nothing about what you received.
4. Does it show the actual data — an HPLC chromatogram and a mass-spec result?
A bare “99% pure” line is a claim. The chromatogram and the MS spectrum are the evidence behind it.
5. Does it confirm identity, not just purity?
HPLC answers “how clean.” Mass spec answers “is this actually the molecule.” Substitution is invisible without it.
6. Can the report be verified on the lab’s own website, not just the vendor’s PDF?
A PDF can be edited in minutes. A report that resolves on the lab’s own domain is far harder to fake.
7. Is the test date recent and consistent with the batch?
A report predating the batch, or years old, is a recycled document — a common tell on fabricated COAs.
8. Is the price plausible for genuinely tested material?
Independent assays cost real money per lot. Pricing far below the market usually means a corner was cut — often the testing.
What a real certificate of analysis actually shows
Most disputes about peptide quality come down to one thing: the buyer was shown a number instead of a document. A purity figure on a product page is marketing. A certificate of analysis is a record of a test run on a specific batch, by a laboratory that can be contacted. These are the fields a genuine report carries, and what each one is for.
How to confirm a report with the laboratory yourself
If a report offers a verification link or a report number, use it, and check that the page you land on is on the laboratory’s own domain rather than a lookalike hosted by the seller. If there is no verification path, you can still email the issuing lab, quote the report number and the lot, and ask whether the document is theirs. Laboratories answer this routinely — it is part of why buyers pay for third-party testing at all. A vendor who reacts badly to that step has told you something useful.
The same checklist, applied to us
It would be hollow to publish a standard and dodge it. BBA Peptides publishes third-party reports from independent laboratories — Freedom Diagnostics and Janoshik — with the lot on the report matching the lot on the vial, the chromatogram and mass-spec data included rather than summarized, and, for Janoshik-issued reports, verification that resolves on the laboratory’s own platform rather than ours. Open the certificate library and run every question in this tool against our own paperwork before buying anything. That is the entire argument.

How do I know if my peptide COA is real?
Work through six checks: the report names an independent laboratory; it carries a lot or batch number that matches the vial in your hand; it shows an HPLC chromatogram rather than a bare percentage; it confirms identity by mass spectrometry, not purity alone; the test date is consistent with the batch; and, where the lab supports it, the report resolves on the laboratory's own website rather than existing only as a PDF the seller sent you. A genuine report invites that scrutiny. A fabricated one wants you to accept a single number.
What should a certificate of analysis include?
At minimum: the analyte (compound) name, the issuing independent laboratory, the lot or batch number, the method used (HPLC for purity, LC-MS or MS for identity), a purity result expressed as a number, and the date the test was run. Reports that also publish the chromatogram and the mass-spec spectrum let you check the underlying data instead of trusting a summary line.
Can I verify a peptide lab report with the laboratory directly?
Sometimes, and it is worth doing. Some laboratories host reports on their own platform, so a report identifier can be checked against the lab's records rather than taken on faith from a PDF. Where a verification link exists, follow it and confirm the document resolves on the laboratory's own domain, not on a page controlled by the seller.
Why do so many research peptides fail purity testing?
Independent testing costs money per lot, so a supplier competing purely on price has a standing incentive to skip it, test one lot and reuse the paperwork, or rely on a certificate supplied by the manufacturer. Published analyses of grey-market material have repeatedly found a meaningful share of samples failing basic purity checks, which is why batch-level, independently verifiable documentation matters more than any purity number printed on a website.
Does this tool store what I enter?
No. The checker runs entirely in your browser. Nothing you select is transmitted, saved, or attached to you: the score is calculated on your own device and disappears when you close the page.
