Third-party HPLC
Every COA on this page reports purity from high-performance liquid chromatography on the actual sold lot — not a generic spec sheet.
US-based independent lab
Ascension Peptides ships representative samples to an independent US laboratory. We don't run the testing; the vendor pays for it and publishes the result.
Verify before you trust
Each row links to the certificate image. The published number is only as good as the linked document. Open it and confirm the lot matches what you receive.
