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 independent 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 admin@peptide-biosciences.com with your order number and the product name.

What Our COAs Confirm

• Purity: HPLC analysis confirming purity to the specification stated for each product
• Identity: Mass spectrometry confirming molecular identity
• Appearance: Visual and physical assessment
• Batch number: Fully traceable to the specific synthesis run

Our Testing Standards

Every batch undergoes independent analytical testing before dispatch. We do not ship any product that fails to meet our purity specifications.
