MAZDUTIDE·US LEGAL STATUS·LAST CHECKED 12 OCT 2026

Is Mazdutide legal?

Not as a drug. Mazdutide has no FDA approval, so selling it for human use breaks federal drug law, and a 'research use only' label does not protect a seller whose site signals human use. It is not a controlled substance, and possessing it is not a federal crime. It is approved in China, which has no effect in the US. Pharmacies cannot compound it.
