Third-Party Laboratory Testing

At Verra, every peptide batch is independently tested by an accredited third-party analytical laboratory before it is made available. We do not rely solely on supplier certificates — we commission our own analysis to verify identity, purity, and the absence of harmful impurities. The results are documented in a Certificate of Analysis (CoA) and are available on this page for full transparency.

What We Test For

• Purity (HPLC): High-Performance Liquid Chromatography confirms peptide purity, typically ≥ 98% for our research-grade products.
• Identity (MS): Mass Spectrometry verifies the molecular weight and sequence of each peptide, confirming it matches the stated compound.
• Appearance & Solubility: Visual and physical inspection to confirm the product meets expected characteristics.

All products are intended strictly for in vitro research and laboratory use only. They are not approved for human or veterinary use.

Certificates of Analysis

The test reports below are issued by an independent, accredited analytical laboratory. 

How to Read a Certificate of Analysis

Each CoA includes the following key fields:

• Compound Name & CAS Number: Identifies the exact peptide tested.
• Purity (%): The HPLC-measured purity of the peptide. Our products meet a minimum threshold of 98%.
• Molecular Weight (MW): Confirmed via mass spectrometry against the theoretical MW of the compound.
• Testing Laboratory: Name and accreditation details of the independent lab that performed the analysis.
• Date of Analysis: The date the test was conducted.
