Retatrutide vs Semaglutide — comparison summary

This page compares Retatrutide and Semaglutide across mechanism of action, receptor targets, molecular weight, solubility and research focus, for in vitro research use only.

Retatrutide

A triple GIP/GLP-1/glucagon receptor agonist.

Mechanism
A single peptide that activates three incretin receptors (GIP, GLP-1 and glucagon), studied for metabolic regulation in the literature.
Receptor targets
GIP-R + GLP-1R + glucagon receptor.
Molecular weight
4731 g/mol
Solubility
Water-soluble
Research focus
A leading subject of metabolic-research interest for combined incretin action.

Semaglutide

A long-acting GLP-1 receptor agonist.

Mechanism
A GLP-1 analogue modified for extended half-life, studied extensively for incretin/metabolic endpoints.
Receptor targets
GLP-1 receptor (GLP-1R).
Molecular weight
4113.6 g/mol
Solubility
Water-soluble
Research focus
One of the most-studied single-incretin agonists in the literature.
