Formulation choices vehicle, pH, penetration enhancers, concentration, and whether the peptide is stabilized against degradation can make the difference between a product that delivers an active dose and one that mostly sits on the surface

Properly stored bacteriostatic water-reconstituted peptide remains stable for approximately 4 to 6 weeks

The transition should include a washout period of at least 1-2 weeks after the last cagrilintide injection, followed by starting the retatrutide titration from the beginning (1 mg weekly)
