Certificates of Analysis & Testing

Certificates of Analysis & Third-Party Testing

Last updated: July 14, 2026

Verification is central to how BioSequence Labs operates. We don’t ask you to take purity on faith — every lot is independently tested and documented.

What we test

  • Purity — HPLC. High-Performance Liquid Chromatography quantifies the purity of each lot.
  • Identity — Mass Spectrometry. MS confirms the molecular identity of the compound.

Independent laboratories

Testing is performed by independent, third-party laboratories — not self-reported in-house figures. This separation is what makes a Certificate of Analysis meaningful.

Your Certificate of Analysis (COA)

Every order includes a lot-specific COA documenting the test results for the exact lot you received, including:

  • Product name and lot number
  • Purity result (HPLC)
  • Identity confirmation (MS)
  • Appearance and relevant physical characteristics

A downloadable COA is published on a product’s page when available; otherwise, the COA for your lot is included with your shipment and available on request at support@biosequencelabs.com.

Manufacturing

Compounds are synthesized in U.S. GMP-compliant facilities, with pure active compound only — no bulking agents or fillers.

Research use only

All testing and documentation is provided to support laboratory research use only. These products are not for human or animal consumption and are not evaluated by the FDA.
