Retatrutide is a triple agonist peptide. It activates three key receptors involved in metabolism and appetite regulation:

Unlike older GLP-1 drugs such as Liraglutide or Semaglutide, Retatrutide taps into a broader metabolic network, resulting in more robust fat loss, improved insulin sensitivity, and potential liver health benefits.
