Selected sources reviewed
Retatrutide, also identified as LY3437943, is an investigational agonist at GIP, GLP-1 and glucagon receptors. A peer-reviewed phase 2 trial and a later sponsor-described phase 3 program are different levels of source evidence.[1][2]
Identity checks
“Triple agonist” names the three receptor targets; it does not identify a separate “GLP-3” receptor or authenticate a product sold under that nickname.[1][2]
Published phase 2 evidence; phase 3 sponsor updates
The published randomized phase 2 trial enrolled 338 adults. Lilly’s current information describes an investigational phase 3 development program. Sponsor updates are identified as sponsor information, not substituted for a peer-reviewed paper or regulatory approval.[1][2]
Regulatory context
FDA states that retatrutide is not a component of an FDA-approved drug. Lilly describes it as investigational. This review does not infer regulatory status for every country.[3][2]

Search results may include unrelated records. A search link does not establish that a matching study exists.
These selected sources describe named substances and studied formulations. They do not authenticate a supplier, a certificate of analysis or the contents of a particular lot, and do not provide instructions for use. “Healing” and other catalogue categories are navigation labels, not evidence of efficacy or treatment recommendations.
