Peptalis publishes what it can prove. Every batch we release passes a defined set of analytical checks, is traced end-to-end, and ships with a Certificate of Analysis in the language of the order. The pages below explain each part of that process.
Analytical testing
Which analytical methods we use to verify identity, purity and content, and why each one is on the panel.
Batch traceability
How each vial you receive traces back to a specific released batch and its Peptalis release report.
Certificate of Analysis (CoA)
What the Peptalis Certificate of Analysis contains, when it is issued and how it reaches you.
Storage and fulfilment
How Peptalis stores research compounds and how orders are prepared, packed and shipped.
How to read a Certificate of Analysis
A guided walk-through of the CoA sections (identity, purity, content, water and residual solvents) and how to interpret typical values.
