Every batch we ship is independently tested by a third-party laboratory. Here’s who, and why.
Every batch of every compound we sell is shipped to an independent third-party analytical laboratory before it reaches our shelf. We do not test our own product. We do not rely on supplier-provided data. We commission a fresh analytical workup against every lot, signed and dated, and we make the result public on the COA Library.
The single most common shortcut in research-peptide retail is in-house or upstream-supplier testing — the lab that produced the batch issues the certificate, with no independent eye on the result. We don’t do this. The lab we work with has no economic stake in our finding a particular outcome.
For each new lot, we ship a representative sample of the lyophilized powder to the lab in its original sealed primary container. The lab logs receipt, photographs the sample, runs the methods listed in Test Methods, and returns a signed report.
The signed report is published, lot-stamped, on the COA Library. No redactions. No selective disclosure. If a lot doesn’t pass, it doesn’t ship and no certificate is issued.
If you’d like to verify a specific lot or request additional testing on a sample you’ve received, contact info@elixserpeptides.com.
