The Three Receptors: How They Work Understanding retatrutide's muscle-sparing advantage requires understanding its three mechanisms: GLP-1 Receptor Activation Primary effect : Appetite suppression, slowed gastric emptying, improved insulin sensitivity Muscle impact : Neutral to slightly protective (reduced hunger preserves protein intake) Competitors : Tirzepatide (50% effect), Semaglutide (100% effect) GIP Receptor Activation Primary effect : Enhanced nutrient absorption, improved insulin secretion, energy expenditure modulation Muscle impact : Moderate protectionimproves protein efficiency at the cellular level Competitors : Tirzepatide (50-75% effect), Semaglutide (0% effect) Glucagon Receptor Activation Primary effect : Mobilizes glucose and fatty acids without excessive proteolysis (muscle breakdown) Muscle impact : Critical protective mechanism tells your body to burn fat preferentially, not protein Competitors : Tirzepatide (0% effect), Semaglutide (0% effect) This glucagon component is the game-changer
