COA verification checklist with a filled example

Use the printable COA worksheet with a filled BPC 157 example, check the report on the issuer’s website, record document gaps and match the lot to your goods.

Use the worksheet with the original

Download the linked PDF and keep it beside the original report, product record and quote. The worksheet organizes a comparison; it is not a product certificate. Enter what each source states, including the source of each field. If information is missing or inconsistent, record the question instead of completing the field from memory. The example below shows how to keep a report’s tested lot separate from the lot you are offered.

Filled example: document identification

These entries reproduce the identification fields of BPC 157 10 mg report BC10-20260908S6179 from our report library. They identify the tested sample and its source without assigning that lot to a new order. Keep the full report number and lot string so another reviewer can find the same document, and record whether the issuer’s online record matches the file.

  • Sample: BC10/BPC157 (BPC 157 10 mg).
  • Issued by: TJQXGD (www.tjqxgd.com).
  • Manufacturer (as printed): https://pllaboratory.com Telegram:@Factory_Global.
  • Report number: BC10-20260908S6179.
  • Lot (batch number): 5828704.
  • Sample received: 2026-09-08; analysis date: 2026-09-08.
  • Issuer’s online record: opened from Verify online on the report page; record whether it matches the file.

Filled example: results and method

Keep the reported measurements in separate worksheet fields. The sample label and the quantity result are not interchangeable. Record qualifiers and units exactly, and retain the original document for checking the transcription.

Do not add a pass decision merely because a result appears precise. Ask for the acceptance criterion that applies to the material being reviewed, and clarify any calculation basis that is not explained.

  • Purity (LCMS/HPLC): 99.87%; specification ≥ 99.0%.
  • Mass spectrum: Detected; specification: Conforms to [M+2H]2⁺, [M-H]-.
  • Peptide weight: 11.39 mg; no specification printed.

Filled example: product and lot comparison

The catalog comparison belongs in its own field. It helps you check the intended package, while the report supplies its own identifiers and results. Keep an offered-lot field open until the quote and corresponding documents provide the connection. The catalog code BC10 printed in the report number and sample name does not complete that connection; only a matching lot number does.

  • Catalog comparison: BC10; BPC 157 10 mg × 10 vials, from the catalog rather than the report.
  • Offered lot: to be confirmed with the quote; compare it with the report’s lot 5828704 and with the label you receive.
  • Acceptance criterion: request the applicable criterion before recording a disposition.
  • Review outcome: the report covers lot 5828704 only; keep the field open until the lot of your goods is confirmed to match.

Carry the report’s limits into your record

NorthVerity states that this report was made on the batch it currently supplies. A report covers only the sample it tested, so ask for the lot number of your goods with your quote.

The issuer (TJQXGD) states that the data come from a third-party partner laboratory, that neither it nor the laboratory holds CMA/CNAS accreditation, and that this document has no legal certification validity.

Results are transcribed from this sample report. The original document takes precedence; these results are not specifications or guarantees for other samples.

Resolve open fields before closing the worksheet

Ask for the documents for the exact lot in your quote. A report describes only the batch it tested, so check that its lot number matches the lot you receive.

Use the current-lot request link for BC10 and identify the open fields from your worksheet. Retain the answer, revised document if provided, and quote together. Update a field only when its supporting record is available; keep the report’s lot separate from the lot confirmed for your goods. Record who checked the documents and the review date so the purchasing team can follow the comparison.
