RETATRUTIDE (RETA)In your orderRetatrutide 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
