Side-by-Side Comparison

Mechanism
Semaglutide

GLP-1 receptor agonist that mimics native GLP-1 to stimulate insulin secretion in a glucose-dependent manner while suppressing glucagon release

Tirzepatide

Dual GIP and GLP-1 receptor agonist that activates both incretin pathways simultaneously for synergistic metabolic effects

Receptor Targets
Semaglutide

GLP-1 receptor only

Tirzepatide

GIP receptor + GLP-1 receptor (dual agonist)

Half-Life
Semaglutide

~7 days (enabling once-weekly dosing)

Tirzepatide

~5 days (once-weekly dosing)

Dosing Frequency
Semaglutide

Once weekly

Tirzepatide

Once weekly

Research Applications
Semaglutide

Type 2 diabetes glycemic control, obesity and weight management, cardiovascular risk reduction, NASH/fatty liver disease, appetite regulation
