Educational overview for record keeping. Not medical advice, and no doses. Check the rules where you live.

What it is

Mazdutide is a dual agonist: a peptide designed to act on the GLP-1 and glucagon receptors. It is based on the structure of oxyntomodulin, a natural gut hormone that acts on both.

How it is usually sold

Research vials: freeze-dried powder labeled by milligrams per vial
The name is often misspelled; pick one spelling for your records

Regulatory status

Mazdutide has been approved in China but is not approved in the U.S. Vials sold "for research use only" are not approved for human use. Check the rules where you live.

Storage basics

Sealed vials are usually kept cold and away from light. Mixed vials are typically refrigerated and used within a window you set from the vendor's guidance.

How The Pep Planner helps you track it

Use the correct spelling when you add it so your stockpile, protocols and history group together. Record the mg per vial and lot, and use the calculator when you mix so the strength is saved with the vial.

Common questions

How is mazdutide different from tirzepatide?
