Test Results & Certificates of Analysis

Transparency is at the core of everything we do. Every batch of peptides we sell is independently tested and verified.

Our Testing Process

Each batch undergoes rigorous quality control through independent third-party laboratories:

• HPLC (High-Performance Liquid Chromatography) — verifies purity levels, confirming 99%+ purity for every product
• Mass Spectrometry — confirms molecular identity and correct sequence
• Endotoxin Testing — ensures products meet safety standards for research use
• Sterility Testing — performed on applicable products

Accessing Test Results

Certificates of Analysis (CoAs) are available for all products. Each CoA includes:

• Product name and batch/lot number
• Purity percentage (HPLC)
• Molecular weight confirmation (MS)
• Appearance and solubility data
• Date of analysis and laboratory identification

To request a CoA for a specific product or batch, please contact us with your order number and product name. We are also working on making CoAs downloadable directly from each product page.

Our Guarantee

If any product does not meet our stated purity specifications, we will replace it or issue a full refund. We stand behind every product we sell.
