Retatrutide has no FDA approval for any use. In practice it is sold as a compounded preparation or labelled "research use only".
Neither of those is an FDA approval. Compounded preparations do not undergo premarket review for safety, effectiveness, or manufacturing quality. "Research use only" is a labelling phrase that lets a seller ship an unapproved substance without formally stating it is for human use — it describes their legal position, not the product's quality.
