Retatrutide: An Investigational Medicine Being Sold Before FDA Approval
Retatrutide is an investigational medicine being studied in clinical trials but is not yet approved by the Food and Drug Administration. The agency states that retatrutide cannot be used in compounding under federal law and has not yet been approved for human use.
But sellers promoting “retatrutide,” “Reta” or “GLP-3” online frequently use terms like “pure,” “lab tested” and “research use only.” Don’t mistake those claims for evidence that a product is legitimate or safe to use.
