Retatrutide and tirzepatide both ship as lyophilized (freeze-dried) powder, so check each one against its own batch-specific Certificate of Analysis (COA) from an independent lab: mass spectrometry should confirm the expected weight for that peptide and HPLC purity should read 98 percent or higher with the trace attached
