FAQ
How much weight can I lose on Wegovy?+
Clinical trials (STEP-1) show Wegovy users lose an average of 16.9% of body weight over 68 weeks. For an 85 kg person that's ~14.4 kg. Results vary based on diet, exercise, and individual metabolism.
Ozempic vs Mounjaro — which is better for weight loss?+
Head-to-head trials (SURMOUNT-5) show tirzepatide (Mounjaro/Zepbound) produces greater average weight loss (~22.5%) than semaglutide (~16.9%). However, best choice depends on insurance, cost, and your doctor's recommendation.
What is compounded semaglutide?+
Compounded semaglutide is a pharmacy-prepared version of the active ingredient in Ozempic/Wegovy. It can cost as little as $146/month vs ~$1,350 for branded Wegovy. Note: FDA has raised safety concerns about unapproved compounded versions — always consult your doctor.
How long does it take to see results?+
Most people notice weight loss within 4–8 weeks, even at the lowest starting dose. Significant results (5%+ body weight) typically appear around weeks 12–16 as the dose escalates.
