RETATRUTIDE
Retatrutide (LY3437943) represents a breakthrough in metabolic peptide research, combining three potent mechanisms of action:
GLP-1 Receptor Agonism – Enhances insulin secretion and satiety
GIP Receptor Modulation – Improves nutrient partitioning
Glucagon Receptor Activity – Increases energy expenditure
Key Research Applications
-
Obesity & Weight Regulation Studies
-
Demonstrated 24.2% body weight reduction in primate models (vs 17.5% with semaglutide)
-
Targets visceral adipose tissue with 38% greater efficacy than dual agonists
-
-
Glucose Metabolism Research
-
Lowers fasting glucose by 2.1-3.8 mmol/L in diabetic models
-
Improves HOMA-IR scores by 62% vs controls
-
-
Lipid Metabolism Investigations
-
Reduces liver fat content by 43-51% in NAFLD models
-
Lowers triglycerides by 29% more than GLP-1 mono-agonists
-
-
Cardiometabolic Protection Studies
-
Shows 22% greater CVD risk reduction vs comparators
-
Preserves lean mass during weight loss (only 8.3% loss vs 14.1% with diet alone)
