Is Mazdutide legal in United Kingdom?

Mazdutide is an investigational or non-UK medicine and has no UK marketing authorisation that we could find. We found no UK marketing authorisation and no MHRA approval announcement for it. The MHRA Products register could not be queried directly on the day of checking, so this rests on MHRA guidance and the absence of any approval notice. UK law does not allow an unauthorised medicine to be sold or supplied, and the MHRA treats a product as a medicine if it is presented as treating disease or acts on the body through a pharmacological effect. Unlicensed 'specials' may only be supplied for an individual patient's clinical need that a licensed product cannot meet, and not for cost or convenience.
