About Semaglutide

Semaglutide is a GLP-1 receptor agonist FDA-approved for type 2 diabetes (Ozempic) and chronic weight management (Wegovy 2.4 mg/week). It works by mimicking GLP-1: increasing glucose-dependent insulin secretion, suppressing glucagon, slowing gastric emptying, and powerfully reducing appetite through brain receptors. Clinical trials showed average weight loss of 15% body weight over 68 weeks. Starting dose: 0.25 mg weekly, titrated every 4 weeks. Compounded semaglutide requires reconstitution with bacteriostatic water. Track your weekly doses and titration schedule with the DoseIQ app.
