Certificates of Analysis

Every batch we sell carries a third-party Certificate of Analysis from Janoshik Analytical, an independent laboratory. Each report covers HPLC purity and mass-spectrometry identity, so you can confirm both how pure the material is and that it is the compound stated on the label. We publish these CoAs on every product page and on this public Reports page before you buy, and each one carries a one-click link to verify.janoshik.com so you can confirm the result directly with the lab rather than taking our word for it.

We are now going a step further. On top of the manufacturer-commissioned Janoshik reports, we commission our own independent testing of selected batches at a separate EU laboratory, Liquilabs in Prague. This is a full safety panel: UHPLC assay and purity, identity confirmation, microbiology (USP 61), bacterial endotoxin (USP 85), and heavy metals (USP 232). It is a second, independent set of eyes on the product, run at a different lab from the one the supply chain uses.

Our commitments to you:

• Testing is per batch, not a one-off sample. Reports are tied to the batch.
• CoAs are published before purchase, so you can read them while you decide.
• Each CoA is batch and lot keyed to the vial you receive, so the report matches what is in your hand.
• A CoA is issued before the batch ships. The report date precedes dispatch.

Honest caveats:

• We do not operate our own laboratory. All testing is carried out by independent third-party labs (Janoshik and Liquilabs).
• Our own independent Liquilabs panel does not yet cover every product and every batch. We are rolling it out batch by batch and will show on each product when an independent panel is available.
• The Janoshik CoAs are issued through the supply chain rather than commissioned by us, which is why we are adding our own independent lab work on top of them.

We would rather tell you exactly what has and has not been tested than make a blanket quality claim. Where a report exists, it is on the page and it is verifiable.
