10–20% body weight in 6–12 months. FDA-approved.
Semaglutide — the active ingredient in Ozempic® and Wegovy® — is the game-changer in assisted, long-term weight loss. Weekly injections that suppress appetite, increase fullness, and help your body use stored fat for energy. Physician-supervised at Iuventus Medical Center Las Vegas.
Semaglutide is not a diet. It changes the biology that makes dieting so hard.
GLP-1 is the hormone your gut releases after eating to tell your brain you're full. Semaglutide mimics it continuously — reducing hunger, extending fullness, and shifting your body toward burning stored fat. The result is weight loss that sticks.
Semaglutide (Wegovy®) is FDA-approved specifically for long-term weight management in adults with obesity (BMI ≥30) or overweight (BMI ≥27) with at least one weight-related condition. Clinical trials show patients lose 10–20% of body weight over 6–12 months — a magnitude of loss previously achievable only with bariatric surgery.
Semaglutide was originally FDA-approved as Ozempic® for type 2 diabetes — it lowers blood sugar by stimulating insulin production in response to meals and suppressing glucagon. For overweight patients with type 2 diabetes or pre-diabetes, semaglutide addresses both conditions simultaneously, often producing significant improvements in HbA1c alongside weight loss.
For patients whose weight is driven by an inability to feel satisfied — eating past fullness, chronic hunger between meals, or strong food cravings — semaglutide directly addresses the neurological hunger-satiety signaling that causes this pattern. Patients consistently report that food simply becomes less compelling, making the behavioral changes of a weight loss program significantly easier to sustain.
The SELECT trial showed semaglutide reduces the risk of major cardiovascular events (heart attack, stroke) by 20% in overweight or obese adults with established cardiovascular disease. Weight loss itself reduces blood pressure, cholesterol, and systemic inflammation — and semaglutide's cardiovascular benefits appear to extend beyond what weight loss alone explains.
One of the most clinically significant challenges in weight management is maintaining loss after achieving it. Semaglutide is used for long-term weight maintenance — sustained weekly injections prevent the metabolic adaptation and appetite rebound that cause regain in patients who have lost weight through other methods.
At Iuventus we offer weekly semaglutide injections for patients seeking to maintain a healthy weight and Body Mass Index — not only for those with significant obesity. For patients who have struggled to sustain a healthy weight and need hormonal appetite support to do so, semaglutide provides a physician-supervised framework for long-term maintenance.
Semaglutide is considered the game-changer in assisted, long-term weight loss. Studies show 10–20% body weight loss in 6–12 months.
This injectable weight loss program can help you feel full faster and longer — making healthier choices sustainable rather than an act of willpower. Physician-supervised at Iuventus Medical Center Las Vegas.
Your gut already has this hormone. Semaglutide amplifies it.
Semaglutide works by mimicking glucagon-like peptide-1 (GLP-1) — a hormone naturally released in the gut when food is consumed. GLP-1 signals to the brain that the stomach is full, stimulates the pancreas to produce insulin in response to meals, and slows gastric emptying (food leaves the stomach more slowly, extending the feeling of fullness). By mimicking this hormone continuously with a weekly injection, semaglutide produces three simultaneous effects: decreased hunger, increased feelings of fullness, and a shift toward using more energy from stored fat.
Originally FDA-approved as Ozempic® for type 2 diabetes in 2017, semaglutide was subsequently approved as Wegovy® for chronic weight management in 2021 — making it one of the most rigorously studied weight loss medications ever approved. Studies have shown that people who take weekly semaglutide injections are able to lose 10–20% of their body weight over a 6–12 month period. This is a magnitude of weight loss that was previously associated only with bariatric surgery.
At Iuventus, semaglutide is prescribed as part of a physician-supervised program — weekly injections combined with guidance on exercise and a reduced-calorie diet. The medication works best as part of a comprehensive program, not as a standalone injection. We monitor your progress, manage any side effects, and adjust your protocol based on your response throughout the program.
While semaglutide is FDA-approved and safe as prescribed, it can be dangerous if not taken correctly. Common side effects include nausea, vomiting, constipation, and abdominal pain — typically mild and resolving as the body adjusts during dose escalation. At Iuventus, every patient on semaglutide has physician oversight throughout the program — we don't prescribe and disappear.
Semaglutide vs. Tirzepatide — GLP-1 vs. dual GLP-1/GIP.
Both are FDA-approved weekly injectable weight loss medications. The difference is mechanism and magnitude. Your physician will recommend based on your weight loss goals, medical history, and tolerance.

The game-changer in assisted long-term weight loss.
No weight loss medication in history has produced the magnitude of results that semaglutide achieves in clinical trials — 10–20% body weight loss over 6–12 months, with cardiovascular benefits that extend beyond the weight loss itself.
From struggling with weight to long-term success.
We evaluate your health condition, BMI, weight-related medical problems, and goals. We review contraindications (personal or family history of thyroid cancer, pancreatitis, severe GI conditions). We confirm semaglutide is the right program for you.
Semaglutide is injected subcutaneously once per week — typically self-administered at home after your first supervised injection at the clinic. Dose is started low and titrated upward over 16–20 weeks to minimize GI side effects.
Semaglutide works best alongside a reduced-calorie diet and regular exercise. We provide individualized guidance — not a starvation protocol, but a sustainable approach that the appetite suppression of the medication makes genuinely easier to follow.
Regular check-ins throughout the program. Weight, BMI, metabolic markers, and side effect profile reviewed. Program adjusted based on your response. Long-term maintenance protocol designed to prevent the weight regain that occurs when medication is stopped without a plan.
Medicine that
gets you.
Semaglutide is only as effective as the program it's part of. At Iuventus, every patient has physician oversight, a diet and exercise plan, and a maintenance strategy — not just a prescription.
Weekly Injections, Supervised Program
We offer weekly semaglutide injections with physician oversight throughout. We don't simply prescribe the medication — we build the program around it and monitor your progress at every stage.
Dose Titration to Minimize Side Effects
Nausea and GI side effects are the most common reason patients stop semaglutide. Our dose titration protocol — starting low and increasing gradually — minimizes these effects and improves long-term adherence significantly.
Diet Guidance That Doesn't Make You Miserable
Our goal is to teach you how to eat right without feeling hungry all the time. The appetite suppression of semaglutide makes this significantly easier — we build on what the medication provides to help you develop habits that last beyond the program.
Long-Term Maintenance Plan
Weight regain after stopping GLP-1 medications is a well-documented challenge. We design a maintenance strategy from the beginning of your program — so that your results are durable, not temporary.
Real weight loss.
