What is Retatrutide?

Retatrutide is a triple-agonist research peptide that activates the GLP-1, GIP, and glucagon receptors. It is studied in preclinical metabolic-pathway models for its combined incretin and glucagonergic effects.

Retatrutide is a next-generation research peptide investigated for its triple receptor agonism — it activates the GLP-1, GIP, and glucagon receptors simultaneously.

Why this matters in research:

  • The GLP-1 axis influences insulin secretion and satiety signaling.
  • The GIP axis is the second major incretin pathway.
  • The glucagon axis contributes to energy expenditure and lipolysis in preclinical models.

By engaging all three, Retatrutide enables researchers to study a more complete picture of incretin- and glucagon-driven metabolic regulation than single- or dual-agonist compounds allow.

Retatrutide is supplied strictly for in-vitro and preclinical laboratory investigation. It is not approved for human therapeutic use. See the Metabolic pathway for related GLP-1 / GIP / glucagon research compounds.
