Analyst Comments

White lyophilized powder, purple-cap vial, received sealed. Retatrutide was not found in the sample (detection limit about 0.2 mg per vial). The dashed trace is a retatrutide reference run on the same method, marking where retatrutide elutes. The only significant peak is an early eluting unidentified UV-absorbing component.
