Wegovy vs Zepbound: both are FDA-approved GLP-1 medications for weight loss. Wegovy (semaglutide) and Zepbound (tirzepatide) differ in mechanism and clinical efficacy. Weight Method offers both from $199/month with virtual consultations and licensed providers.

Overview

Wegovy (semaglutide, Novo Nordisk) and Zepbound (tirzepatide, Eli Lilly) are two separate FDA-approved medications indicated for chronic weight management, made by different manufacturers. Both are once-weekly injections, but they differ in mechanism: Wegovy is a GLP-1 receptor agonist, while Zepbound is a dual GIP/GLP-1 receptor agonist. Weight Method does not dispense or prescribe either brand-name product; our program provides compounded semaglutide and compounded tirzepatide through licensed providers and U.S.-licensed pharmacies. Which medication is appropriate for you is a decision made by a licensed provider based on your individual medical profile.

Key Fact

Wegovy (semaglutide) is a GLP-1 receptor agonist; Zepbound (tirzepatide) is a dual GIP/GLP-1 receptor agonist. Both are separate FDA-approved branded products for chronic weight management from different manufacturers — and both are different from Weight Method's compounded program.

Wegovy and Zepbound are different molecules from different manufacturers, each FDA-approved for chronic weight management.

Wegovy and Zepbound are distinct FDA-approved branded products from different manufacturers with different mechanisms; neither is what Weight Method dispenses.
