Independent lab testing
Batch Test Ledger
Purity you can check for yourself. Every Kairo Labs production lot is assayed by an independent laboratory (Janoshik Analytical) and its Certificate of Analysis is published here, verifiable by the lot number on your vial — no login, no request, just the report.
Published lots
Our independent batch-testing program is rolling out.
Every production lot is being submitted to Janoshik Analytical for HPLC-MS purity and identity analysis, and each Certificate of Analysis will be published here the moment it is issued — tied to the lot number on the vial so you can confirm it independently. This page is the permanent home for those reports as lots come online.
A production lot is a defined quantity of material made in a single run. Before it ships, a sample is sent to an independent analytical lab that measures two things that matter most for a peptide reference material: purity, by high-performance liquid chromatography (HPLC), and identity, by mass spectrometry, which confirms the measured mass matches the compound's expected molecular weight.
The lab returns a Certificate of Analysis — a lot-specific document with the result, the method, and a report number. We publish that report here against its lot number, unedited. Where the lab provides public verification, the ledger links straight to it, so the proof doesn't depend on us hosting a PDF.
One report per production lot — a COA never carries over to a different run.
Purity figures are transcribed verbatim from the lab report.
Reports link out to the lab's own verification wherever it is offered.
Why per-lot, third-party proof
Anyone can print “99% pure” on a page. What's harder to fake — and what a careful researcher looks for — is a report from a lab with no stake in the result, tied to the specific lot in hand, and confirmable at the source. That is the entire point of this ledger: not a marketing number about the product line, but a checkable measurement of the exact material you received. See the guides on reading a COA and third-party testing for the full picture.
Frequently asked
Are Kairo Labs peptides third-party lab tested?
Yes — production lots are submitted to an accredited independent laboratory (Janoshik Analytical) for analysis, and each report is published on this page, indexed by lot number. Third-party testing means the lab has no stake in the outcome: it measures the material and reports what it finds.
What does the Certificate of Analysis (COA) measure?
A COA is a lot-specific analytical summary. For a peptide reference material it typically reports purity by HPLC (the percentage of the main peak) and identity by mass spectrometry (confirming the measured mass matches the expected molecular weight), along with the lot number, test date, and the method used. Because it is lot-specific, each production run carries its own document.
How do I verify the lot I received?
Enter the lot number printed on your vial into the verify box above. If that lot has a published COA it appears with the lab, purity, method, and a link to the report PDF — plus, where the lab offers it, an independent verification link so you can confirm the document directly with the lab rather than taking our word for it.
Why does each batch need its own test?
A COA from one lot does not certify a different lot of the same product — purity and identity are properties of a specific production run. Per-batch testing is the honest standard: it ties a measured result to the exact material you have, not to a marketing claim about the product line in general.
Is this for human use?
No. All Kairo Labs materials are research reference materials for in-vitro and laboratory research use only. Nothing on this page describes, recommends, or authorizes any human or animal use, and purity data is analytical information, not a safety or efficacy claim.
