How does tirzepatide differ from semaglutide?

Tirzepatide is a dual GIP/GLP-1 receptor agonist, while semaglutide targets GLP-1 receptors only. Phase III clinical trial data (SURMOUNT vs STEP programs) showed differentiated body composition and glycemic outcomes.

Is tirzepatide sold here for personal or clinical use?

No. PurePep Vital does not sell products; linked research-grade tirzepatide is positioned for laboratory and analytical work only. FDA-approved pharmaceutical tirzepatide (Mounjaro, Zepbound) is a separate regulated category.
