Fat Loss

Retatrutide

Triple Agonist · GLP-1 / GIP / Glucagon

Retatrutide engages GLP-1, GIP and glucagon receptors in a single molecule, producing a metabolic effect that single- and dual-agonists cannot match. Appetite drops, energy expenditure rises, and lipolysis accelerates while lean tissue is preserved.
