Certificates of Analysis & Testing Methodology

Every batch of SS-31 we sell is tested prior to listing. Depending on the grade, testing
includes High-Performance Liquid Chromatography (HPLC) for purity quantification and Mass
Spectrometry (MS) for identity confirmation.

How to Read Your COA

• Lot/Batch Number: matches the number printed on your vial label
• Purity (HPLC): the percentage purity of the peptide content
• Identity (MS): confirms the molecular weight matches SS-31’s expected mass
• Appearance/Solubility: a visual and solubility QC check
