Mechanism of Action
Retatrutide activates three metabolic receptors simultaneously:
GLP‑1 – appetite reduction, slower gastric emptying
GIP – enhanced insulin response
Glucagon – increased energy expenditure and fat breakdown
This triple pathway produces greater weight‑loss effects than GLP‑1‑only or dual agonists.
Starting dose: ~2 mg weekly
