Batch verification
Confirm batch identity, certificate status, and third-party testing references for Cobalt research compounds.
Verify a batch
Enter the batch number exactly as it is printed on your product label, dashes included.
Found on your product label — type it exactly as printed, dashes included
Verification chain
Batch identity
Match the batch number printed on the product label.
Purity data
Review the purity values published on the certificate for that batch.
Third-party check
Enter the verification key at the laboratory's own site to read their record.
Analytical methods
- HPLC: purity analysis
- High-Performance Liquid Chromatography (HPLC) is the industry standard for determining chemical purity. Where a batch has been tested and falls below our 99% purity threshold it is destroyed, not reclassified and not returned to the supplier. The recorded purity result for a tested batch is shown on its published certificate as an area percentage.
- The laboratory report behind it
- A published certificate transcribes the purity and content figures reported for the batch. It is not the laboratory's own report and does not reproduce chromatograms, mass data or identity confirmation. Where a batch carries a verification key, entering it at the laboratory's site returns their record of the analysis, which is the authoritative document.

Frequently asked questions
How do I verify my Certificate of Analysis?
Enter your batch number (found on your product label) in the search box above. Batch numbers take one of two forms — SKU-YYMM and SKU-DDMMYY — so enter yours exactly as it is printed on the label. An older label carrying an LP- prefix still verifies. If you are unable to find your batch number, navigate to the product page for your variant and it will list the latest batch for that product.
How recent are the test results?
Where testing has been commissioned, it is arranged on receipt of stock from our suppliers, and the test date is displayed on the published certificate. We recommend using compounds within the recommended storage timeframe to maintain purity and stability.
Will the laboratory report show my in-house batch reference?
Not in every case. Cobalt Peptides may use internal batch references for stock tracking, and some of our published laboratory reports are supplier-level third-party CoAs. Third-party laboratory documentation may therefore reference the corresponding supplier batch or sample rather than the Cobalt Peptides internal batch code. Our published CoAs provide the testing information available for the relevant product or batch.
What if my batch number isn't found?
If your batch number is not found, please verify that you entered it exactly as printed on your label — either SKU-YYMM or SKU-DDMMYY. If the issue persists, please contact our support team with your order details.
