How It Works
Peptide
Mechanism
These peptides work through multiple complementary mechanisms: (1) GLP-1 receptor activation reduces appetite via hypothalamic signaling, slows gastric emptying, and enhances glucose-dependent insulin secretion; (2) GIP receptor co-agonism amplifies satiety signals and may improve adipose tissue function; (3) Glucagon receptor activation increases energy expenditure and hepatic fatty acid oxidation; (4) Amylin analogs provide additional satiety through area postrema signaling and slow gastric emptying.
Obesity involves dysregulation of multiple hormonal axes controlling energy intake and expenditure. Single-target approaches often yield modest results due to compensatory mechanisms. Multi-receptor agonists address this by simultaneously modulating appetite (GLP-1), nutrient sensing (GIP), energy expenditure (glucagon), and satiety signaling (amylin), creating synergistic effects that exceed monotherapy outcomes.
