What is Retatrutide

Retatrutide is a unique triple agonist that simultaneously activates GIP, GLP-1, and glucagon receptors, combining appetite suppression with increased energy expenditure via the glucagon component. In the phase II study published in the New England Journal of Medicine (2023), participants achieved a mean weight loss of approximately 24% at the 12 mg dose over 48 weeks. It is in development by Eli Lilly in the phase III TRIUMPH program.

Funciona, mas exige consistência. As informações de armazenamento e reconstituição foram essenciais pra mim.

Estou satisfeito até agora. Recomendo ler as contraindicações antes, como o site orienta.

Efeito mais sutil no meu caso, mas pode ser questão de tempo de uso. O material do site é honesto sobre isso.
