Third-Party Verified —
Every Batch
Each production lot is submitted to an independent, ISO/IEC 17025 accredited laboratory for comprehensive analysis.
Testing includes:
Quality Assurance
Precision verified. Accountability documented.
At Catalyst Bio Labs, quality is not assumed — it is verified. Every batch we produce undergoes independent analytical testing before release.
Transparency and documented validation are foundational to how we operate.

Why It Matters
Validation isn't optional. It's operational policy.
Independent analytical verification is what makes the rest of the supply chain trustworthy.
Research integrity
Documented purity and identity keep your data defensible.
Experimental consistency
Standardized testing means standardized inputs across studies.
Supply chain reliability
Domestic manufacturing and accredited testing remove the unknowns.
Batch-to-batch reproducibility
Every lot is held to the same documented analytical bar.
Documentation
Every batch comes with a COA.
Certificates of Analysis document each lot's identity, purity, and analytical results — with lot number, test date, and the name of the testing laboratory. Nothing is hidden, nothing is estimated.
Every Catalyst Bio Labs COA is also independently verifiable on Horizon Analytical's site, so you don't have to take our word for anything.
