Reading a Real Certificate: BPC-157 Lot BC10-2026-001

Most explanations of a certificate of analysis describe a certificate in general. This one reads a single real document from top to bottom: the signed certificate for lot BC10-2026-001 of BPC-157. Every figure quoted below is printed on that certificate. Open it beside this page — the BPC-157 COA — and follow along.

The header: which sample this is

Before any result, the certificate says what was tested and by whom.

• Laboratory: ILS Laboratories, with its street address in San Diego, CA, and the name of the lab director who signed.
• COA number: COA-2026-RJUHAJ. This identifies the document itself.
• Lot: BC10-2026-001. This is the number that has to match the label on the vial. A certificate for a different lot says nothing about the vial in your hand.
• Dates: received 07/01/2026, tested 07/15/2026, issued 7/15/2026.
• Sample: lyophilized, tested under the laboratory's "Full QC Panel".
• Overall result: PASS.
• Access code: WB5BX29R. This is what lets you confirm the document with the laboratory, covered at the end.

The footer carries one more line worth reading: the certificate "relates only to the items tested". It describes the sample the laboratory received, not every vial ever sold under the same name.

Purity: 99.72% by HPLC

The line reads Peptide Purity (HPLC), specification >= 95.0%, result 99.72%, status PASS.

HPLC separates the sample into its components and measures how much of the detected signal belongs to the main peak. A result of 99.72% means that share of the peptide-related signal was the main component, and 0.28% was something else. It is a statement about how clean the sample is. It is not, by itself, a statement about what the main component is, or how much of it is in the vial. Those are the next two lines. The difference is covered in what an HPLC purity number does and doesn't prove.

Identity: confirmed against a reference standard

The line reads Identity (HPLC-RTM), specification BPC-157 Confirmed, result Confirmed, status PASS.

RTM is retention-time matching. The laboratory runs a reference standard of BPC-157 under the same conditions as the sample and checks that the sample's main peak arrives at the same time. A match is the evidence that the main peak is BPC-157 and not another compound that happens to be pure.

Net peptide content: 10.46 mg

The line reads Net Peptide Content, specification Report Only, result 10.46 mg.

This is the measured amount of peptide in the vial, against a label of 10 mg. "Report Only" means the laboratory states the figure without grading it pass or fail. A lyophilized vial also holds counter-ions and residual water, so the weight of the powder and the weight of the peptide are not the same number. This line is the second one.

Sterility and endotoxin

Two separate lines, often confused.

• Sterility (PCR): specification No Growth, result No Growth, status PASS. This screens the sample for microbial contamination.
• Endotoxin (USP <85>): specification Report Result, result NMT 0.05 EU/mL, status Reported. Endotoxin is a component of bacterial cell walls that can remain after the organisms are gone, which is why it is tested separately from sterility.

The certificate prints its own note on the endotoxin line: the result is reported as a quantitative value, and because acceptable limits vary by product type and matrix, no universal pass/fail threshold applies to research-use-only material. That is why the status says "Reported" and not "PASS".

Heavy metals: five elements, each with its own limit

Under Heavy Metals Analysis (ICP-MS) the certificate lists arsenic, cadmium, lead, mercury and chromium. Each has its own limit — not more than 1.5 ppm for arsenic and mercury, 0.5 ppm for cadmium, 1.0 ppm for lead and 10.0 ppm for chromium — and each carries its own status. On this certificate all five read PASS.

For the element-by-element figures, read the laboratory's own record, reached with the access code below. That is the version nobody but the laboratory can edit.

Fentanyl screen

The line reads Fentanyl Screen, specification Immunoassay, 50 ng/mL cutoff, result Not Detected, status PASS. An immunoassay screen answers one question: was fentanyl present at or above the stated cutoff. It is a contamination check, and the cutoff is part of the result.

What this certificate does not tell you

• Anything about another lot. The results belong to BC10-2026-001.
• Anything about storage after testing. The laboratory tested the sample it received on the dates printed.
• Whether the material suits a particular experiment. That is a judgement for the researcher, made with the figures above.

This material is sold for in-vitro laboratory research only.

Check it yourself

Do not rely on this page, or on our copy of the PDF. Go to ils-lab.com/verify, enter access code WB5BX29R, and the laboratory shows its own record of this lot: the product, the lot number, the results and the signatory. We do not host that page and cannot edit it.

Every other published lot and its access code is on our verification page, and the general method — for any vendor's certificate — is in how to verify a COA with the issuing laboratory.
