Question 1

How does semaglutide differ from tirzepatide?

Accepted Answer

Semaglutide is a single GLP-1 agonist. Tirzepatide is a dual GLP-1/GIP agonist that has shown greater weight reduction in head-to-head trials (~22% vs ~17%).

Question 2

Is research-grade semaglutide the same as Ozempic?

Accepted Answer

Research-grade semaglutide contains the same molecule but is not manufactured under the same pharmaceutical GMP standards as the branded product and is designated for research use only.

Question 3

Why does nausea occur?

Accepted Answer

GLP-1 receptor activation in the brainstem area postrema and delayed gastric emptying both contribute. Gradual dose escalation minimizes this effect.
