How we verify

Purity You Can Verify

Not every peptide clears our bar. We source selectively and publish available independent Certificates of Analysis by product and strength, including the lot number shown on each certificate. 99%+ HPLC purity reported on published COAs.

  1. 01

    The lab has a name

    Genesis Bio Labs. Every certificate we publish names the lab, and the full report is hosted at genesisbiolabs.org.

  2. 02

    Match the lot on your vial to the certificate

    Batch-level, not brand-level. If your lot isn’t listed yet, ask us and we’ll send the matching documentation.

  3. 03

    Measured, not claimed

    RP-HPLC purity, a potency assay against label claim, and a 7-panel QC run on each published certificate.

FAQ

Frequently Asked Questions

Testing, verification and scope — the three we get asked most. Anything else, we answer by email, and the full FAQ covers storage and ordering.

Ask us something else

We publish the available independent laboratory certificate for each listed product and strength. Review the certificate and its lot number before ordering.

Compare the lot number on your vial with the certificate shown for that product and strength. If the lot is not listed, contact us for the matching documentation before use.

No. All products are for laboratory and research use only — not for human or animal consumption.
