How to Verify an ILS Laboratories COA: Access Code and Portal Lookup

ILS Laboratories is a San Diego testing laboratory that issues certificates of analysis for research peptides, ours among them. Every ILS certificate can be looked up on the laboratory's own website, and the lookup takes about a minute. This page covers both ways in, what the lab's record contains, which fields to compare, and the limits of what a matching record proves. At the end we run the check on one of our own lots, including the part where our copy and the lab's record disagree.

Two ways to reach the lab's record

1. The access code, at ils-lab.com/verify

Type ils-lab.com/verify into your browser yourself rather than following a link from a seller. The laboratory's page asks for the access code from the certificate. According to the lab, the code is printed in bold under the QR code in the header, appears again in the signature area at the foot of each page, and is typically seven or eight letters and numbers.

2. The QR code, which opens the portal

Scanning the QR code on the certificate opens a page on portal.ils-lab.com/verify/ followed by a long unique ID. Before you read anything on that page, check the address bar. The host must be portal.ils-lab.com. A QR code or link printed by a seller is only as trustworthy as the domain it lands on, and the access-code route avoids that question entirely. The portal page builds itself after it loads, so give it a moment before concluding it is blank.

Some certificates carry only the access code and no portal link. Use the first route for those.

What the ILS record shows

A resolved record is a structured page, not a scanned PDF. In the order it appears:

• Tested for: the client that submitted the sample.
• Product information: product name, lot number, appearance, test type, date received and the date the analysis was confirmed.
• Main results: HPLC purity against its limit, net peptide content in mg, and identity.
• Elemental impurities by ICP-MS, element by element, with the lab's limit and a status for each.
• Sterility (PCR) and endotoxin (USP <85>) results, each with its specification.
• Notes and methodology: how each test was run.
• Signature block: the signing lab director and date, the COA number, the access code and the issue date.

Compare in this order

1. Lot number. This must match your certificate and the label on your vial. If it doesn't, nothing below it matters.
2. COA number and access code. These should be identical on the paper and on the record.
3. Product name and labeled amount.
4. Purity and net peptide content. These should match to the digit.
5. Identity, elemental impurities, sterility and endotoxin, row by row, including the method stated in the notes.
6. Dates and signatory.

Where the PDF and the record differ, rely on the record. The laboratory says each certificate is tied to a unique verification ID and that results cannot be altered after release. The PDF is a copy that has passed through other hands.

What a matching record does and doesn't prove

• The lab didn't choose or label the sample. The record's own notes say that product names, lot numbers and labeled content come from the party that submitted the sample and were not independently verified by the lab. A matching record proves that ILS tested a sample submitted under that name and lot. It cannot show that your vial came from the same material. That link is lot traceability, and it's the seller's job to make it checkable.
• Accreditation doesn't cover peptides. ILS's verification page says its quality management system is based on ISO/IEC 17025, and in the same section that peptide testing is not within any accreditation scope. If a certificate header or a seller implies otherwise (ours included), go by the laboratory's own statement. There's more on why the distinction matters in what third-party testing actually means.
• Identity is by retention time, not mass. The record's notes describe identification by comparing chromatographic retention time with a reference standard, not mass spectrometry. The difference is explained in HPLC purity vs. identity.
• The limits are the lab's own. The notes describe the elemental-impurity limits as internal screening limits for research-use materials, not a pharmacopeial monograph. The endotoxin row is reported against the client's specification. Read both as quality-control measurements of a research material.

Worked example: our BPC-157 lot

Lot BC10-2026-001 of BPC-157 carries access code WB5BX29R. Its QR code opens the laboratory's record for this lot.

These fields agree between our certificate and the lab's record:

• product BPC-157, 10
• lot BC10-2026-001
• COA number COA-2026-RJUHAJ
• HPLC purity 99.72%
• net peptide content 10.46 mg
• identity confirmed
• signed by the lab director, Dr. Greg Kalyuzhny, on 07/15/2026

Some fields do not agree:

• Elemental impurities. The elemental-impurity rows in the PDF we host differ from the laboratory's record. Every value in both versions is within the lab's limits.
• Endotoxin. The PDF names a kinetic turbidimetric endotoxin method, while the laboratory's record states kinetic chromogenic. The endotoxin row is also reported against a different criterion.

The metals discrepancy appears on 14 of our lots. We've raised it with the laboratory. Until it is resolved, the laboratory's record is the authoritative version: wherever our PDF and the portal disagree, use the portal.

Every published lot is listed with its access code and portal link on our verification page. The codes are also printed on the paper in your order, so you don't need our site to run the check.

If a code doesn't resolve

Re-enter it carefully, since letters and digits are easy to confuse. Confirm that you are on ils-lab.com and not a lookalike. Then ask the seller for the certificate as issued. A code the issuing laboratory can't resolve is the strongest warning sign covered in COA red flags.

The same check, for any laboratory

ILS is one lab among several. The general workflow behind this page works for any certificate that names its laboratory: find the lab independently, use its own lookup, and compare field by field. It is set out in how to verify any COA with the issuing laboratory, and how to read a COA explains what each result means once you have confirmed it.
