Certificate of analysis on every lot

Research peptides with the paperwork to prove it.

Every lot is tested by an independent laboratory for potency, purity and sterility. The signed certificate is published under the lot number on your vial — and can be verified against the lab's own record.

Why third-party testing

A certificate is only worth the laboratory behind it.

Most suppliers publish a manufacturer's own spec sheet. We send every lot to Plasmid Analytical, an independent laboratory, and publish what comes back — signed, dated, and verifiable against the lab's record.

  1. 01
    An independent laboratory and a named analyst

    The synthesis lab never grades its own work. Each certificate is signed by the analyst who ran it, with the client and manufacturer of record stated.

  2. 02
    Method, specification and result — side by side

    Potency by HPLC-UV against the label claim, purity by HPLC area with a ≥98% floor. Blends list every component so each mass is confirmed individually.

  3. 03
    Sterility by USP <71>

    Membrane filtration with a 14-day incubation. A purity number without a sterility result only tells half the story.

  4. 04
    A verification key you can check yourself

    Every certificate carries a QR code and a 12-character key. Enter it at the laboratory's own verification page — a certificate that does not match their record was not issued by them.
