Verity Peptides supplies research chemicals intended strictly for in-vitro research use only. Independent verification of what is in each vial is central to that purpose. This page explains how every lot is tested, what a Certificate of Analysis (COA) reports, and how you can confirm that a COA is authentic and matched to the exact lot you received.
Every lot is independently tested
Each production lot of every product we offer is submitted to an independent, third-party analytical laboratory for testing before it is released for sale. The laboratory operates separately from Verity Peptides and from our suppliers, so the results reflect an outside assessment rather than an in-house claim. Testing is performed on a per-lot basis, which means that two vials carrying different lot numbers are backed by their own separate analyses rather than a single shared report.
What a Certificate of Analysis reports
A Certificate of Analysis is the laboratory document that records the analytical results for a specific lot. Depending on the compound and the test panel applied, a COA we publish may include the following:
- Identity — confirmation that the material corresponds to the labeled compound.
- Purity by HPLC — the purity of the material measured by high-performance liquid chromatography, reported as a percentage.
- Mass spectrometry — where applicable, molecular-weight confirmation supporting the identity result.
- Endotoxin — where applicable, an endotoxin (LPS) measurement for the lot.
- Sterility — where applicable, a sterility result for the lot.
Not every test applies to every compound or presentation, so the specific panel shown on a given COA reflects the tests that are relevant to that lot. Each COA identifies the lot or batch number it covers, the testing laboratory, the methods used, and the date of analysis.
How you receive a lot-matched COA
Every order ships with the Certificate of Analysis for the exact lot supplied, and you can request the certificate for any lot number through our Contact page at any time. As lots are released, their certificates are also published on the corresponding product pages. Because the document is lot-matched, the report you receive corresponds to the actual material being supplied rather than to a generic or compound-level summary.
How to confirm a COA is authentic
Each vial is printed with a lot or batch number. That number is the key to verification: it ties the physical material in your hands to a specific laboratory report. To confirm that a COA is authentic and matched to your lot, follow these steps:
- Locate the lot or batch number printed on the vial.
- Open the Certificate of Analysis that accompanied your order (or the certificate published on the product page). Confirm that the lot or batch number on the COA matches the number printed on your vial exactly.
- Check that the identity and purity results, and any additional results shown, correspond to the product you ordered.
- If you would like an independent confirmation, or if the number on your vial does not match the COA you received, submit the lot number through our Contact page and we will verify the certificate for that lot and respond to you directly.
We encourage you to perform this lot-number check whenever you receive an order. Matching the printed lot number against the published COA is the most reliable way to confirm that the documentation corresponds to the exact material you received.
