Retatrutide is a synthetic 39-amino-acid peptide engineered to act on three receptors at once: GLP-1, GIP and glucagon. By engaging all three incretin and glucagon pathways, it is used to model how combined receptor signaling influences energy balance in preclinical systems.

Common research applications include:

Metabolic and energy-expenditure models
Incretin receptor pharmacology
Comparative studies against single- and dual-agonist peptides
