Retatrutide + Cagrilintide

Also known as: Triple + Amylin Combo, Reta-Cagri

A combination of triple agonist retatrutide with amylin analog cagrilintide for maximum weight loss.

Overview

This combination pairs retatrutide (GLP-1/GIP/glucagon triple agonist) with cagrilintide (amylin analog) for potentially superior weight loss through four complementary pathways. This represents one of the most aggressive peptide approaches to obesity treatment.

Mechanism of Action

Retatrutide: activates GLP-1, GIP, and glucagon receptors for appetite suppression, insulin secretion, and thermogenesis. Cagrilintide: activates amylin receptors for additional appetite suppression and gastric slowing. Four-receptor approach.

Pharmacokinetics

Both are long-acting with weekly dosing. Subcutaneous administration.
