About this Certificate of Analysis
A Certificate of Analysis records the analytical identity and net peptide purity of a specific batch. For Retatrutide, quantity and purity are confirmed by LC-MS/MS against the labelled specification. Because each batch is tested and archived separately, this record remains available for reference after a batch has sold through. Quantum Peptides publishes a batch-coded COA for every compound as part of its transparency standard for research buyers in Canada.
