Tirzepatide: The Hierarchy Weight Loss Efficacy Retatrutide : 22.5% average (triple-agonist) Tirzepatide : 21% average (dual-agonist) Semaglutide : 15-17% average (single-agonist) Metabolic Rate Impact Retatrutide : 5-10% increase (glucagon pathway) Tirzepatide : 1-2% increase (GIP adds minor boost) Semaglutide : Minimal increase (appetite suppression primary) Muscle Preservation Retatrutide : Excellent (glucagon pathway + higher metabolic rate) Tirzepatide : Good (GIP benefits) Semaglutide : Adequate (GLP-1 only, slower recomposition) Best For Retatrutide : Body recomposition, aggressive fat loss, metabolic health Tirzepatide : Sustained weight loss, transitioning from semaglutide Semaglutide : First-time users, mild obesity, cost-conscious FAQ Q: Is retatrutide better for muscle gain than tirzepatide
