Mechanism of Action
Retatrutide (GLP-3 R) is a 39-amino acid peptide engineered from the native glucose-dependent insulinotropic polypeptide (GIP) sequence. Strategic amino acid substitutions and a C-terminal fatty acid side chain extend its half-life and increase albumin binding. Retatrutide’s unique design allows it to simultaneously activate three metabolic hormone receptors:
- GLP-1 receptor – increases insulin secretion, suppresses glucagon release, slows gastric emptying and promotes satiety.
- GIP receptor – stimulates insulin secretion and enhances lipid metabolism.
- Glucagon receptor – increases energy expenditure and promotes fat oxidation.
By engaging all three receptors at once, retatrutide delivers synergistic effects on weight management, glycemic control and lipid metabolism.

Research Applications
Retatrutide is an investigational peptide under active study for metabolic health. Published pre-clinical and early clinical research demonstrates profound reductions in body weight, liver fat and blood pressure while improving insulin sensitivity. Its triple agonism offers a powerful tool for researchers studying:
- Appetite regulation and energy expenditure pathways.
- Glucose tolerance and insulin secretion dynamics.
- Lipid metabolism and hepatic steatosis.
- Multi-hormone signalling interactions in obesity and type 2 diabetes models.
