Is retatrutide investigational or illegal?

On this site's national fields it is investigational, not approved. That is a regulatory status, not a verdict that owning a named molecule is a crime. Until the FDA, and the matching agencies in the UK, Australia, and Canada, approve a finished product, retatrutide is not a legal prescription drug in those countries. Sellers offering it are offering an unapproved research chemical. Investigational is the accurate word for the trial programme. Illegal is the loose word people use when they mean unapproved for human use. This dataset has no state-by-state map. This FAQ does not invent a criminal code. Full record at /compounds/retatrutide.
