Certificate of Analysis peptides UK: COA checks explained

A Certificate of Analysis, often shortened to COA, is used to document analytical information for a product batch. UK researchers searching for COA peptides usually want clearer evidence around purity, identity, batch references and quality handling.

A COA should support research procurement decisions, but it should never be used to imply a product is suitable for human consumption, therapeutic use, veterinary use, diagnostic use or cosmetic use. Proforma Peptides supplies products strictly for laboratory research use only.

What to check on a peptide COA

  • Product name and batch reference.
  • Purity or analytical testing method, such as HPLC.
  • Date or batch-specific traceability details.
  • Consistency between the COA and the product page.
