Hormonal

Tirzepatide achieves body weight loss of ≥ 5% significantly faster than semaglutide 1 mg in patients with type 2 diabetes.

If your goal is weight loss alongside blood sugar control, tirzepatide (10 or 15 mg) will likely get you to a 5% body weight reduction in about 12 weeks, which is half the time it takes with semaglutide 1 mg. This benefit persists despite the slower dose escalation schedule required to manage side effects.

GoodSupportsHIGH confidence
In SURPASS-2, the median time to first achieve a body weight loss of > 5% was 16.0 weeks (5 mg) and 12.4 weeks (10 and 15 mg) with tirzepatide than with semaglutide 1 mg (24.0 weeks).
