Tirzepatide: Dosage, Protocol, and Research Guide
Dual GIP/GLP-1 receptor agonist for enhanced weight loss and metabolic control
Mechanism
Novel dual incretin agonist targeting both GIP and GLP-1 receptors. The GIP component enhances the GLP-1 effects, leading to superior glucose control and weight loss through synergistic metabolic pathways including enhanced insulin sensitivity and lipolysis.
