How do I verify a Regena Peptides COA is real?

Every batch is issued a unique verification key by Janoshik Analytical. Enter the key at www.janoshik.com/verify to independently confirm HPLC purity, mass-spec identity, water content and batch date.

Are COAs issued for every single batch?

Yes. No Regena batch is released for sale until an independent third-party laboratory — Janoshik Analytical by default — has signed a COA showing ≥99% HPLC main-peak purity, correct molecular weight and passing water content and endotoxin results.

Do you retain historical COAs?

Yes. Every historical COA remains available on the /download-coa library, indexed by product and batch number, so a research buyer can retrieve the analytical record for any past shipment.

Which analytical methods appear on the COA?

Reversed-phase HPLC for main-peak purity, mass spectrometry for molecular identity, Karl Fischer or LOD for water content, ion chromatography for acetate/TFA content and LAL for endotoxin. Each field is explained on /trust/how-to-read-a-coa.

Can I share a COA with a colleague or auditor?

Yes — each COA PDF has a stable URL and a Janoshik verification key. Both can be shared freely for audit or comparator-study reference.
