How to Verify an ExoLabz Certificate of Analysis

Every certificate we publish names the laboratory that produced it and carries the key or code that laboratory uses to confirm the document is its own. This guide walks through checking one of our certificates from start to finish: finding the page, opening the laboratory’s verification route, comparing the two documents field by field, and matching the vial in your hand to the batch the report covers.

Step 1: find the certificate page

There are two routes to a certificate. A product page links to any published report for that product, and the certificates index lists every report we have published so far, grouped by compound. We publish certificates for tested lots; not every product or every lot has one, and a product page without a certificate link means no report has been uploaded for it yet, not that the product was tested and withheld.

Each certificate page reproduces the laboratory’s document and writes out every field in plain text beneath it. The two pages used as examples throughout this guide are BPC-157 10 mg, Janoshik task #93626 and CJC-1295 & Ipamorelin 10 mg, ILS certificate COA-2026-5BEDMI. Open whichever one matches the product you are checking.

Step 2: read the laboratory and the document number

Two laboratories appear on our certificates. Janoshik identifies each job by a task number, written as #93626 in the example above, and prints a verification key on the report; for task #93626 that key is KY8VES262D7Z. ILS Laboratories in San Diego, which is ISO/IEC 17025 accredited under PJLA scope, identifies each job by a certificate number such as COA-2026-5BEDMI and prints an access code on the certificate; for that certificate the code is VS6B9TNJ.

Both the number and the key or code are written out on our certificate page. Copy the key or code exactly as it appears, character for character. If the certificate page you are looking at names any laboratory other than these two, or carries no key or code at all, stop and go to step 6, because that is not a document we published.

Step 3: open the laboratory’s verification page

For a Janoshik report, go to janoshik.com/verify/ and enter the verification key. For an ILS certificate, go to portal.ils-lab.com and enter the access code printed on the certificate. In each case the laboratory returns its own record of the document from its own system. We have no access to either site and cannot alter what it shows, which is the point of the exercise: the laboratory’s copy is the authority, and ours is a reproduction of it.

If the key or code is not recognised, check it once more against our page before drawing any conclusion; a single transposed character is the most common reason for a miss. If it still fails, regard the certificate as unverified and go to step 6.

Step 4: compare the two documents field by field

Put the laboratory’s record and our certificate page side by side and work down the list below. Every value that appears on both should be identical. A reproduction that differs from the laboratory’s copy in any field, however small, is a reproduction that has been altered, and that is the failure this whole process exists to catch.

• Laboratory name, and the accreditation statement where the laboratory gives one.
• Task or certificate number, exactly as the laboratory formats it.
• Dates received and analysed.
• Sample description: the compound name and the declared quantity on the label.
• Measured quantity (net content), where the laboratory reports one.
• Purity, as a percentage, with the technique stated.
• Identity: the technique used and whether the laboratory reports the compound as confirmed.
• Method: the instrument, column, gradient, wavelength or other settings the laboratory lists.
• Scope statement: anything the laboratory says the report does not cover.

Our certificate page also carries two things the laboratory’s record will not: photographs of the batch, and the cap and crimp colours of that batch. Those are ours, and they are what step 5 relies on.

What each field proves

How to read a peptide certificate of analysis goes through the same fields on a real report and explains why two laboratories can report different purity figures for the same material.

Step 5: match the vial to the batch

Our vials carry no printed lot number. A certificate is tied to a lot by the cap colour and the crimp colour of the vials in the batch photographs on the certificate page. Hold your vial against those photographs in daylight and compare both colours; the cap and the crimp are chosen as a pair, so both must match, not just one.

If both colours match, the report covers the lot your vial came from. If either colour differs from every published certificate for that product, your vial is from a lot without a published report. That is a gap in coverage, not a failed test, and new reports are uploaded as they come back from the laboratories; it is also exactly the situation the purity guarantee exists for.

Step 6: if anything differs

Write to us through the contact page with the address of the certificate page, the field that differs and what the laboratory’s record shows instead, and a photograph of your vial showing the cap and crimp. We will answer with what we find; a document that does not match its laboratory record is withdrawn from the site.

If your concern is the material rather than the document, use the purity guarantee: have any vial tested by an independent laboratory, and if it falls short of the specification on its certificate we refund the product and the testing fee once the unused material comes back with the laboratory’s report. Testing a single vial from a new order is the simplest way to check us that does not depend on taking our word for anything.
