FROM THE LIBRARY
Compounds in focus.
Metabolic
Retatrutide
Retatrutide (LY3437943) is an investigational triple agonist that activates GIP, GLP-1 and glucagon receptors in a single molecule.
Metabolic
Tirzepatide
Tirzepatide is a dual GIP and GLP-1 receptor agonist.
Growth & hormones
Sermorelin
Sermorelin is the first 29 amino acids of growth hormone-releasing hormone (GHRH), the active portion of the natural hormone.
