Is retatrutide FDA approved?

No, it is still investigational. Its Phase 3 trial, TRIUMPH-1, randomized 2,339 participants and reported results in May 2026, with a company submission for approval expected later in 2026. Until the FDA reviews and approves it, retatrutide is not a legal prescription drug anywhere, which is why every seller offering it is doing so as an unapproved research chemical rather than a medicine.
