Lazarus Labs provides two types of Certificates of Analysis (COAs), both verified through Janoshik Analytical. We have published 12 unredacted, branded COAs that display our brand name, product batch numbers, and all identifiers. We also carry supplier COAs where certain fields are intentionally redacted — specifically the supplier name, unique identifier codes, and certain manufacturer details — to protect our supply chain and prevent source identification.
This is standard practice within our operating model and does not affect the validity or legitimacy of the test results.
The products are the same across both COA types — our branded COAs and our supplier COAs cover the same peptides. On our website, we list our own batch number alongside each redacted supplier COA so you can match your vial's batch number to the correct test report.
What's visible on redacted (supplier) COAs
Peptide content and identity confirmation — confirms the peptide is what we say it is
Purity levels of the product — confirms the percentage purity from independent testing
Test date
Testing methodology
Janoshik Analytical's verification details
This means you can fully assess product quality and authenticity from a supplier COA, even with the supplier-identifying fields redacted. Our 12 branded COAs have no redactions — all fields are fully visible.
Limitations in Lab Verification Links and Publication Timing
In some cases, supplier COAs may not include a report number, which can limit the availability of direct lab-site verification links. Additionally, COAs are often published as test results become available, meaning that not all results may be accessible at a given time. Supplier COAs are conducted regularly, and only certain results may be published depending on the testing schedule.
Moving to fully branded COAs
We are currently working to replace all remaining redacted supplier COAs with our own branded, unredacted versions showing our brand name and batch numbers. We expect to have this complete by end of August / early September 2026.
