Tirzepatide

The Dual Agonist That Beats Ozempic

FDA ApprovedMounjaroZepbound

Quick Take

Tirzepatide is the new heavyweight champion of weight loss peptides. As a dual GLP-1/GIP agonist, it outperforms semaglutide in head-to-head trials. People are losing 20-25% of their body weight. It's what everyone wants when Ozempic isn't enough.

How It Works

Simple Explanation

Tirzepatide activates TWO hunger-related receptors instead of one. It hits both GLP-1 (like Ozempic) and GIP receptors, creating a more powerful appetite-suppressing and metabolic effect.

🔬 Technical Details (Click to expand)

As a dual GIP/GLP-1 receptor agonist, tirzepatide provides synergistic effects on appetite, glucose metabolism, and energy expenditure. GIP receptor activation enhances the GLP-1 effects and may improve tolerability while boosting fat oxidation.
