GLP-1 Receptor Activation This is the same pathway used by Semaglutide (Ozempic, Wegovy): Suppresses appetite via hypothalamic signaling Delays gastric emptying , prolonging fullness Improves insulin secretion and glucose control Lowers postprandial glucose and insulin resistance GIP Receptor Activation Shared with Tirzepatide, GIP provides several synergistic effects: Enhances insulin release in response to meals May reduce GI side effects (like nausea) seen with GLP-1s alone Potentially improves lipid metabolism and adipose tissue response Glucagon Receptor Activation This is where Retatrutide takes a leap beyond dual agonists: Increases energy expenditure and fat oxidation Mobilizes stored fat through hepatic lipolysis May preserve or enhance lean mass during weight loss Supports brown fat activation and thermogenesis The addition of glucagon receptor activation to GLP-1 and GIP may enhance fat oxidation and energy burn beyond whats seen with dual agonists. Coskun et al., Cell Metabolism Together, these pathways work synergistically: GLP-1 blunts hunger , GIP improves insulin dynamics , and glucagon turns up fat-burning efficiency

Most patients can expect to see immediate improvements in gait, balance, motor coordination and mood
Naltrexone: This blocks opioid receptors, helps prevent the euphoric and sedative effects of opioids, and suppresses cravings
Where GLP-1 primarily activates hypothalamic neurons involved in energy balance, amylin targets hindbrain circuits that regulate meal-specific satiety and food reward
Severe or continuing vomiting or diarrhea can lead to dehydration, which may harm the kidneys
