Glucagon-Like Peptide-1 (GLP-1) Receptor Agonist
Semaglutide and Tirzepatide are highly effective medications for managing obesity and supporting weight loss. They work by mimicking natural hormones—GLP-1, and in the case of Tirzepatide, both GLP-1 and GIP—that help regulate appetite, blood sugar, and metabolism.
GLP-1 medications have been used in medicine since 2005 for the treatment of type 2 diabetes. They have been approved for weight loss since 2014.
