Semaglutide is a GLP-1 receptor agonist that helps regulate blood sugar levels and supports weight loss. It mimics a hormone in your body called glucagon-like peptide-1 (GLP-1), which helps control insulin production, reduce appetite, and slow digestion.
Semaglutide is typically administered as a once-weekly injection under the skin (subcutaneous). It can be injected into the thigh, abdomen, or upper arm.
Tirzepatide is a newer GLP-1 and GIP receptor agonist. Like Semaglutide, it helps regulate blood sugar levels, but it also targets the glucose-dependent insulinotropic peptide (GIP) receptor, which works in combination with GLP-1 to help reduce blood sugar and improve insulin sensitivity.
Tirzepatide is also administered as a once-weekly injection, similar to Semaglutide. It can be injected into the abdomen, thigh, or upper arm.
