HPLC-verified purity. Our Retatrutide is tested by HPLC, with the purity figure and chromatogram published on the COA so you can confirm it directly.
Mass spec identity. The COA includes mass spectrometry data confirming the molecular weight matches Retatrutide (LY3437943), so you know you have the correct compound.
Batch-tied COA. Each COA matches the lot number on the vial. No generic or recycled documents.
