Retatrutide (LY3437943)
Retatrutide (also known as LY3437943) is an investigational synthetic peptide supplied strictly for laboratory and research use only.
Overview for Research Purposes
Retatrutide is a 39-amino-acid peptide designed as a triple hormone receptor agonist. In preclinical and early clinical research models, it has been studied for its potential to simultaneously activate three key receptors involved in metabolic regulation: GLP-1 (glucagon-like peptide-1), GIP (glucose-dependent insulinotropic polypeptide), and glucagon (GCGR).
Key Structural Features
• Sequence: Proprietary 39-amino-acid chain with non-coded amino acids and fatty acid conjugation for enhanced stability and prolonged half-life
• Length: 39 amino acids
• Half-life: Approximately 6 days in research models, supporting once-weekly dosing in experimental settings
Primary Research Areas (Preclinical Models Only)
• GLP-1, GIP, and glucagon receptor co-activation
• Glucose homeostasis and insulin secretion pathways
• Appetite regulation and energy expenditure
• Lipid metabolism and body composition changes
• Potential effects on liver fat content and metabolic dysfunction
• Cardiovascular and renal markers in metabolic disease models
Preclinical animal studies and early Phase 2 human trials have explored retatrutide's impact on body weight, glycemic control, and metabolic parameters in controlled settings. Ongoing Phase 3 trials are investigating longer-term outcomes in obesity, type 2 diabetes, and related conditions. No product is approved for therapeutic use as of 2026.
