Single vs. Dual Receptor Agonism
Both Semaglutide and Tirzepatide are FDA-approved clinical peptides for weight management. However, their molecular actions differ:
- Semaglutide (GLP-1 Single Agonist): Mimics the GLP-1 hormone to regulate insulin release, gastric emptying, and brain satiety centers.
- Tirzepatide (GLP-1 & GIP Dual Agonist): Targets both GLP-1 and Glucose-Dependent Insulinotropic Polypeptide (GIP) receptors. GIP synergizes with GLP-1 to enhance glucose regulation and fat metabolism, frequently resulting in greater total weight loss in clinical trials.
