Weight Loss Pen
A weight loss pen is a small injector used to deliver peptide medications—typically GLP‑1 or dual GLP‑1/GIP receptor agonists—under the skin to help reduce appetite, promote fullness, slow digestion, and support weight loss when combined with diet and exercise.
💉 How It Works
Active ingredients: Most pens contain medications like liraglutide (Saxenda), semaglutide (Ozempic, Wegovy), or tirzepatide (Mounjaro). These mimic hormones that regulate appetite and blood sugar
💉Mechanism of action:
Send signals to your brain that you're full sooner.
Slow gastric emptying.
Enhance insulin secretion (especially when food is eaten), stabilizing blood sugar
