We partner with independent, accredited third-party laboratories to verify the identity, purity, and quality of every peptide batch we offer.
Testing Pipeline
- Incoming Verification: Batches are received with manufacturer COAs.
- Third-Party Testing: Samples are sent to independent labs for HPLC and mass spectrometry analysis.
- Documentation: Results are compiled into Certificates of Analysis.
- Release: Products are released for sale only after meeting our quality specifications.
Standards
- Minimum 99% HPLC purity for peptide content
- Mass spectrometry confirmation of identity
- Batch-specific documentation
- No batch mixing—each COA corresponds to a single lot
Transparency
COAs are available for all products. Researchers can request documentation before purchase and receive batch-specific COAs with every order. We believe transparency is essential for trustworthy research.
