The paper trail with every shipment.

A Certificate of Analysis on every lot, and the ability to verify it independently — because a supplier's own document is a starting point, not a guarantee.

Placeholder — pending verification

The manufacturing partner’s registration and inspection status, and any quality-system certifications, will be stated here once confirmed. Until then, no specific regulatory status is claimed. (Real credentials to be supplied by Cornerstone Peptides.)

How you verify quality

  1. 01

    Each lot ships with a per-lot Certificate of Analysis, with raw HPLC and mass-spec chromatograms attached.

  2. 02

    You may request independent third-party verification at Janoshik or Auxilium on any lot — the first lot of any new molecule at our expense.

  3. 03

    Any lot that fails third-party verification (more than 5% deviation on HPLC, or any failing identity test) is replaced or fully credited.

  4. 04

    Long-term buyers can establish a standing testing program where every Nth lot is pulled automatically for independent verification.
