What are Semaglutide, Tirzepatide, and Retatrutide?

Semaglutide, Tirzepatide, and Retatrutide are clinically researched peptides used for weight management and metabolic research. Semaglutide is a GLP-1 receptor agonist, Tirzepatide is a dual GLP-1 and GIP receptor agonist, and Retatrutide is a triple agonist targeting GLP-1, GIP, and glucagon receptors.
