How to verify a peptide COA.
A Certificate of Analysis is only as good as the lab behind it, and a PDF can be edited or borrowed. Many independent testing labs let anyone check a report against the lab's own record in under a minute; here is how, and what should make you look twice.
A COA is a document, not proof.
A Certificate of Analysis is a PDF or an image, and either can be edited, reused across lots or copied from another seller. Independent testing has found real gaps between label and contents: one published analysis of peptide vials bought from three online shops, each sold as 10 mg, measured between 4.3 and 8.8 mg.
Verification closes that gap. When the issuing lab confirms a report from its own records, you know the document is genuine and unaltered, which is the one step a seller cannot do on the lab's behalf.
Lab verification portals.
Labs that support verification print a code, a QR code or a permanent link on each certificate. Entering it on the lab's own website returns the lab's copy of the report, so you can compare it line by line with the one you were given.
| Lab | Where to verify | What you enter |
|---|---|---|
| ILS Laboratories (San Diego, CA) | portal.ils-lab.com | Scan the QR code or enter the access code; a valid report opens under a Verified Certificate banner |
| Janoshik Analytical (Prague) | janoshik.com/verification | The task number and unique key printed on the report |
| Vanguard Laboratory (Olympia, WA) | verifiedbyvanguard.com | The QR code or permalink to the lab-hosted report |
If a lab offers no way to check a report, ask the lab directly, and treat a report nobody can confirm with caution.
Checking a report in five steps.
- Find the laboratory name, the certificate number and the lot number on the COA.
- Open the lab's verification page from the lab's own website, or scan the QR code printed on the report.
- Enter the code. A genuine report returns the lab's copy; an invalid code is rejected.
- Compare the lab's copy with yours: compound, labeled amount, lot, test date and every result should match exactly.
- Match the lot on the report to the lot printed on your vial.
Signs a COA may not be genuine.
- No laboratory named, or the only lab is the seller's own.
- No certificate number, QR code or other way to check it with the lab.
- The lab's copy shows different numbers, a different client or a different date.
- The same report appears for different lots, amounts or compounds.
- The lot on the report does not match the vial.
- Purity with no identity result: a pure sample of the wrong compound still reads as pure.

Verifying a Helion report.
Helion's CJC-1295 + Ipamorelin 10mg, lot 335XA, was tested by ILS Laboratories under certificate COA-2026-955706, with access code JDMZ7Q7Z printed on the report. Opening its ILS verification page returns the lab's copy under a Verified Certificate banner, tested for Helion, with the same 99.85% HPLC purity, 10.51 mg measured content and 0.081 EU/mL endotoxin shown in the COA Portal.
Every published Helion report has a Verify at ILS link in the COA Portal and on its product page. The COA reading guide explains what each line on the report means, and the peptide testing guide explains how each test works.

Questions (6)
How do I know if a peptide COA is real?
Check it with the lab that issued it. Labs that support verification print a code, QR code or link on the report, and the lab's own copy should match yours exactly: compound, amount, lot, date and results.
What does third-party tested mean?
The material was tested by an independent laboratory rather than by the seller. A third-party report names the lab and the lot, and ideally can be checked on the lab's own website.
How do I verify an ILS Laboratories COA?
Scan the QR code on the report or enter its access code on portal.ils-lab.com. A genuine report opens under a Verified Certificate banner; an invalid code is rejected.
How do I verify a Janoshik COA?
Enter the task number and the unique key printed on the report on Janoshik's verification page, janoshik.com/verification.
Can a COA be faked?
A PDF can be edited, reused or copied from another seller, which is why verification matters. A report the issuing lab confirms from its own records has not been altered.
Are Helion's COAs verifiable?
Yes. Every published Helion report comes from ILS Laboratories and links to its ILS verification page from the COA Portal and the product pages.
