Tirzepatide vs semaglutide 2.4 mg in non-diabetic obesity SURMOUNT-5 direct head-to-head, -20.2% vs -13.7% at 72 weeks: Aronne NEJM 2025
Published work links its activity to nitric-oxide pathway signaling, FAK-paxillin cell-adhesion pathways, growth-factor receptor expression, and dopaminergic and serotonergic systems
Once a needle has entered the vial, contamination risk starts immediately
General storage advice (all tirzepatide products) Keep all pens, vials, needles, and syringes out of reach of children
Its mechanism specifically excludes the N-terminal domain of growth hormone that binds to receptors mediating glucose metabolism, so it triggers lipolysis without affecting insulin or blood sugar levels
