What GLP-3 (RT) is

Retatrutide (research code LY3437943), sometimes referred to as GLP-3, is an investigational triple-hormone receptor agonist that acts on the GLP-1, GIP, and glucagon receptors. It is supplied as an analytical-grade reference material for laboratory research.

What the research has examined

Published research has examined retatrutide primarily in metabolic-science contexts, including clinical trials measuring changes in body weight and metabolic markers.

Listing an area of study is not a claim about any product or outcome. These references are provided so qualified researchers can locate the primary literature. All materials are supplied for laboratory research use only.
