Retatrutide vs Tirzepatide — comparison summary

This page compares Retatrutide and Tirzepatide 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.

Tirzepatide

A dual GIP/GLP-1 receptor agonist.

Mechanism
A single peptide activating both GIP and GLP-1 receptors, studied for metabolic and incretin research.
Receptor targets
GIP receptor + GLP-1 receptor.
Molecular weight
4813.5 g/mol
Solubility
Water-soluble
Research focus
Widely studied for combined incretin-pathway metabolic effects.
