Semaglutide vs Tirzepatide

Which should you choose? Here's what you need to know.

The short answer

Tirzepatide targets two receptors (GIP + GLP-1) and has shown slightly more weight loss in trials. Semaglutide is more established with longer real-world data.

Semaglutide

Weight Loss (GLP-1)

Semaglutide is the active ingredient in Ozempic and Wegovy. It's a single GLP-1 receptor agonist with years of clinical data and FDA approval for both diabetes and weight loss.

Choose Semaglutide if:

You want a well-established option with the most real-world data, or your provider is more familiar with GLP-1 dosing protocols.

Tirzepatide

Weight Loss (GLP-1)

Tirzepatide (Mounjaro/Zepbound) is a newer dual-action peptide hitting both GIP and GLP-1 receptors. Clinical trials showed up to 22.5% body weight reduction.

Choose Tirzepatide if:

You want the latest generation with potentially greater weight loss, or you haven't responded well to GLP-1-only options.

Where does this data come from?

We re-check vendor prices continuously and score vendors on Finnrick blind-test results — samples bought anonymously and sent to a lab, not vendor claims. No vendor can pay to rank higher. See our full methodology.
