Retatrutide is a novel triple agonist targeting GLP-1, GIP, and glucagon receptors[1], studied for substantial weight loss and metabolic improvement in obesity and type 2 diabetes[2][3]. With an extended half-life of approximately 6 days, this peptide enables convenient once-weekly subcutaneous dosing with a gradual titration protocol to optimize tolerability[1][4].
- Reconstitute: Add 2.0 mL bacteriostatic water → 10.0 mg/mL concentration for optimal weekly doses.
- Typical weekly range: 2–12 mg once weekly (gradual escalation over 12+ weeks).
- Easy measuring: At 10.0 mg/mL, 1 unit = 0.01 mL ≈ 100 mcg on a U-100 insulin syringe.
- Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) and use within 2–4 weeks.
