Top 5 Weight-Loss JabsWhich One Actually Gives You the Most for Your Money?

GLP-1 (glucagon-like peptide-1) is a gut hormone your body already makes. It tells your brain you're full, tells your stomach to empty more slowly, and helps your pancreas release insulin at the right time. Weight-loss jabs are lab-made versions of that hormone — molecules like semaglutide (Ozempic®, Wegovy®) and tirzepatide (Mounjaro®, Zepbound®) — designed to do the same job, only longer and stronger.

A weekly self-injection suppresses appetite, increases satiety and slows gastric emptying. Newer dual agonists like tirzepatide add GIP, a second gut hormone, which appears to push weight-loss numbers higher again.

Published trial data on the branded medications puts average weight reduction between 15% and 22% of starting body weight over roughly 68 weeks, depending on the molecule and dose. Programme data self-reported by the providers on this page sits in a similar band over 6-month windows.

"The medication does about a third of the work. Consistency and the right dose titration do the other two-thirds."

None of that happens on week one. Every provider titrates the dose up over several weeks, which is why the quality of the clinical team you can actually reach matters as much as the price you paid for the box.
