A COA is the lab's report for one specific batch. Anyone can make a PDF. The only thing that makes one real is finding the same report in the lab's own database. Here's a real one, field by field.
Peptide Restore BPC-157 10 mg, lot 260518BPC01, tested by Freedom Diagnostics, search code Pept2606010568, reported 03 Jun 2026. We opened the vendor's PDF, looked the code up at the lab, and compared the two files. They were identical. Every field below comes from that document. The lab's copy is here.
| Field | On the example | What it means | What to do with it |
|---|---|---|---|
| Client | Peptide Restore | Who paid for the test. The vendor, not you. | Confirm it's the company you're ordering from — not a look-alike. |
| Accession # | 2606010568 | The lab's internal ID for this report. | Copy it exactly. |
| Search code | Pept2606010568 | The lookup key. On this lab's certificates: first four letters of the client name + accession number. | Enter it at the lab's public COA Look Up. If it returns "no document," stop. The PDF is unverified. |
| Received / Reported | 06/01/2026 · 06/03/2026 | When the lab got the sample and when it reported. | Record the reported date. Don't use an old lot's report for a new lot. |
| Lot | 260518BPC01 | The batch. Must match the vial and the listing. | All three strings identical, or it isn't documented. Older certificates from this lab read "N/A" here — treat that as a gap. |
| Product | BPC-157 10mg | What the vendor says it sent. | Match to the listing name exactly. Blends must name every component. |
| Identity (LC-MS) | BPC-157 | The lab weighed the molecule and confirmed it's the one on the label. | The line that matters most for names like "TB-500," which can mean two different molecules. |
| Purity (HPLC-UV) | 99.35% | How much of the powder is the named molecule, by the stated method. | Per lot only. A listing's "meets or exceeds 99%" is a claim; this is a measurement. Some lots from the same vendor read 97–98%. |
| Net content | 12.90 mg | What was actually in the vial. | Often over label. On blends, check each component — one lot we checked ran 9.57 mg on a 10 mg label. |
| Endotoxin (LAL, USP <85>) | Pass · Pass | A bacterial-contamination screen, two replicates, method named. | Not every certificate includes it. "Pass" without a method is not a result. |
| Chromatogram / mass confirmation | One dominant peak; [M+H]⁺ and [M+2H]²⁺ labeled | The pictures behind the numbers. | You don't need to read them. You need them to be there. |
| Signature | Principal chemist | A named person signed it. | Present or absent. |
If the lookup returns nothing, don't "fix" the code and don't cite numbers from that file. Two of ten Peptide Restore certificates we checked in September 2026 were not found at the lab — both the newest lot of their product. We list them as unverified until that resolves.
