What makes the Good Peptide good?

Goodness is all about getting back to the basics. Back to purity, back to research-grade, back to traceability.

  • Certificate of Analysis detail showing purity results

    Purity

    HPLC-UV measures purity, while LC-MS confirms identity. Both results are recorded for the tested lot.

  • Certificate of Analysis detail showing the testing organization

    Documentation

    The report identifies the testing organization, principal chemist, methods, and reported results.

  • Certificate of Analysis detail showing lot and method fields

    COAs

    Each certificate records the product, lot, dates, methods, results, and testing details in one report.

  • Certificate of Analysis detail showing the accession number

    Tracking

    The report records the product, lot, accession number, and search code for the tested sample.

Match the vial to the report

Use the lot number or search code to locate the Certificate of Analysis.
