Retatrutide is a peptide that acts as a triple agonist, targeting the GIP, GLP-1, and glucagon receptors. It is studied in metabolic research and supplied as a reference compound for research use only.
What triple agonist means
The GLP-1 family has grown from single-target compounds to multi-target ones. Semaglutide targets one receptor, Tirzepatide targets two, and Retatrutide targets three: it adds the glucagon receptor to the GIP and GLP-1 targets.
How it is studied
In the laboratory, Retatrutide is studied in metabolic research as the most recent step in this peptide family. The research-grade compound is a study tool, not a therapeutic, supplied for research use only.

A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
