Quality & Documentation
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.
Per-lot Certificate of Analysis
Every shipment carries a lot-specific COA with HPLC and mass-spec identity, attached as raw chromatograms. Review a representative certificate before you buy.
View a sample COA →Independent third-party verification
Any lot can be verified at an independent analytical lab — Janoshik or Auxilium — on request, and we pay for the first lot of any new molecule. Results go to you directly.
Janoshik Analytical →Replace-or-credit guarantee
Any lot that fails independent verification — more than 5% deviation on HPLC, or any failing identity test — is replaced or fully credited. We compete on the paper trail, not on price.

Our manufacturing partner holds active registrations and quality-system certifications appropriate to API supply. Specific registrations, FEI number, inspection history, and current certificates are released to qualified buyers under NDA during qualification.
Cornerstone Peptide Co. operates as the U.S. commercial partner; we do not ourselves hold FDA registration.

How you verify quality
- 01
Each lot ships with a per-lot Certificate of Analysis, with raw HPLC and mass-spec chromatograms attached.

- 03
Any lot that fails third-party verification (more than 5% deviation on HPLC, or any failing identity test) is replaced or fully credited.
- 04
Long-term buyers can establish a standing testing program where every Nth lot is pulled automatically for independent verification.
Material is supplied as active pharmaceutical ingredient and research material. Determination of intended use and compliance with all applicable regulations are the responsibility of the purchaser.
