Frequently Asked Questions

All Aceso Peptides compounds are tested via HPLC (High-Performance Liquid Chromatography) and have a minimum purity of 98%. Most compounds exceed 99% purity. The exact purity percentage for each batch is documented in the Certificate of Analysis.

All compounds undergo HPLC purity analysis and mass spectrometry confirmation at independent, accredited UK laboratories. Testing is performed by third parties with no affiliation to Aceso Peptides, ensuring objective analytical results.

A Certificate of Analysis is a document issued by our independent testing laboratory confirming the analytical results for a specific batch. It includes purity percentage, molecular weight confirmation, and other relevant analytical data. COAs are available for every batch via our lab results page.

All peptides are supplied as lyophilised (freeze-dried) powder in clearly labelled vials. Each vial includes the compound name, batch number, quantity, and storage instructions.

Lyophilised peptides stored at -20°C typically remain stable for 24+ months. Upon reconstitution, the solution should be used within the timeframe specified in the product documentation. We recommend reviewing the COA for specific stability data.
