Certificates of Analysis

At Peptide Biosciences, every batch is independently tested to verify purity, identity, and quality. Our Certificates of Analysis (COAs) are produced by accredited third-party laboratories and are available for every product we sell.

How to Request a COA

Your COA is included with every order. If you require a copy for a specific batch, please contact us at info@peptide-biosciences.com with your order number and the product name.

What Our COAs Confirm

• Purity: HPLC analysis confirming ≥99% purity
• Identity: Mass spectrometry confirming molecular identity
• Appearance: Visual and physical assessment
• Batch number: Fully traceable to the specific synthesis run
