Comparison
Semaglutide vs. tirzepatide: what's the difference?
Both are weekly injectable treatments for weight management. The main difference is how many hormone signals they act on.
In short
The verifiable difference between the two is the mechanism: tirzepatide acts on two receptors (GLP-1 and GIP) and semaglutide on one (GLP-1). Which suits your case depends on your tolerance, medical history, and cost — not the mechanism alone. A licensed provider reviews your case and advises which applies.
