Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist used for the treatment of obesity and diabetes. In lyophilized form, semaglutide is supplied as a freeze-dried powder that helps preserve stability and potency.

Before administration, the powder must be reconstituted with a sterile diluent to prepare it for injection. The compounded semaglutide lyophilized powder you have been prescribed uses the same active pharmaceutical ingredient as brand-name forms of semaglutide.
