Currently published Certificates of Analysis are available in the Lazarus Labs COA library and on the relevant product pages. Availability varies by product, strength and batch.
If you cannot find the exact certificate, that alone does not establish whether the batch has or has not been tested. Reply in your existing support conversation with the product, strength, batch code if present, and order number so the team can check. Do not use a certificate for another strength as proof for the one you received.
What a certificate reports
A COA is a laboratory report for the product, strength and batch identified on that report. Read its actual results: identity, measured content per vial and purity are separate fields, and a field may not be reported. Where a blend report lists the identity and amount of each component without a purity percentage, there is no purity percentage to quote.
Do not treat a COA as evidence of an unreported test. In particular, purity or identity results alone do not establish endotoxin, sterility, heavy-metal, residual-solvent or mass-spectrometry testing. A missing result means it is not reported on that certificate. There is no promised date for additional tests unless a current published update provides one.
Branded and supplier reports
The library includes Lazarus Labs branded reports and supplier reports. Supplier details or identifiers may be redacted to protect the supply chain; the published analytical results remain visible. Use the laboratory verification link when one is available.
The batch printed on your vial can differ from a supplier batch reference. Match it using the mapping shown in the library, or ask the support team to confirm it. Some older vial labels may not have a printed batch code. A product-name match alone does not prove a particular vial belongs to the tested batch.
Independent results or a testing discrepancy
If an independent laboratory result differs from the published COA, our support team needs to review the specific evidence. Reply in your existing support conversation with the product and strength, the batch printed on the vial, the order number if available, and a copy or link to the laboratory report. You do not need to open another email thread.
If your question concerns a refund, retesting costs, evidence requirements or permission to reproduce Lazarus Labs documents, include that question with the report. These outcomes and permissions cannot be confirmed from the published COA alone; a team member needs to answer the specific request.
