Semaglutide vs Tirzepatide — comparison summary

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

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.

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.
