Zepbound® (tirzepatide) is the first and only FDA-approved dual GIP/GLP-1 receptor agonist for weight loss — with clinical trials showing up to 22.5% body weight reduction. Real prescription, real results, licensed physician online.
Zepbound® works differently than every other weight loss drug on the market. Here's the science — and why it matters for your results.
Zepbound® (tirzepatide) works differently from semaglutide — and that difference is significant. While Ozempic® and Wegovy® target only the GLP-1 receptor, Zepbound® activates two hormone receptors simultaneously: GIP (glucose-dependent insulinotropic polypeptide) AND GLP-1. This dual-action mechanism is why Zepbound® consistently produces more dramatic weight loss than GLP-1-only medications.
GLP-1 suppresses appetite and slows gastric emptying. GIP enhances the effect by improving fat metabolism and amplifying the satiety signal. Together, these two pathways create a synergistic effect that neither hormone achieves alone. This is not a subtle improvement — it translates to meaningfully greater weight loss for most patients.
The SURMOUNT-1 clinical trial, the largest weight-loss drug trial of its kind, showed that Zepbound® patients lost an average of up to 22.5% of their body weight over 72 weeks — results that surpassed every prior weight loss medication in history. For a 250-pound patient, that means up to 56 pounds lost on average.
More recently, the SURMOUNT-5 trial put Zepbound® head-to-head against Wegovy® — the first-ever direct comparison of these two medications. The result? Zepbound® patients lost 47% more weight than Wegovy® patients over the same 72-week period. Zepbound® won decisively. FDA-approved in November 2023 for chronic weight management in adults, it has rapidly become the most sought-after prescription weight loss treatment available.
Zepbound® is FDA-approved for adults who meet specific clinical criteria. Most patients who want it do qualify — here's what to know before your consultation.
Adults with a body mass index at or above 30 qualify for Zepbound® without any additional conditions required.
Adults with a BMI of 27–29.9 qualify if they have at least one weight-related condition: high blood pressure, type 2 diabetes, sleep apnea, or dyslipidemia.
Zepbound® is FDA-approved for adults aged 18 and up. It has not been approved for use in patients under 18 years of age.
Zepbound® is not recommended during pregnancy or breastfeeding. Patients should use contraception and discuss family planning with their physician.
Zepbound® should not be used by patients with a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2 (MEN2).
Patients with a known history of serious hypersensitivity reactions to tirzepatide or any ingredient in Zepbound® are not candidates for this medication.

Three simple steps from your couch to your Zepbound® prescription. No waiting rooms, no referrals, no hassle.
Fill out a confidential medical history form online in about 5 minutes. Our licensed physicians review your health profile, current medications, weight-loss history, BMI, and eligibility for Zepbound®. The entire process is HIPAA-secure and completely confidential. There is no charge for the initial assessment.
If you are a good candidate, a board-certified physician writes your Zepbound® prescription and sends it directly to your pharmacy. We coordinate with your insurance company and handle prior authorization paperwork on your behalf — so you can focus on your health, not the administrative headache.
Your Zepbound® auto-injector pens ship directly to your preferred pharmacy or home address, depending on your coverage. Monthly check-ins with your Truventa physician keep you on track, and dose adjustments are made based on your response and tolerance. We're with you every step of the way.
Zepbound® is always started at the lowest dose and gradually increased over time. This approach minimizes side effects and helps your body adapt to the medication.
The starter dose is designed to build tolerance, not to produce maximum weight loss. Most patients experience mild appetite reduction at this stage. Any gastrointestinal side effects are typically at their mildest, and most patients tolerate this phase very well. Your physician will check in before escalating the dose.
At 5mg, you enter the first true therapeutic dose. Appetite suppression becomes noticeably stronger, and most patients report meaningful reductions in hunger and food cravings — especially for high-calorie, high-sugar foods. Average weight loss by week 8 is typically 4–8 pounds depending on starting weight and lifestyle.
The 7.5mg dose increases weight loss efficacy further. Patients who tolerate 5mg well typically advance here. Weight loss accelerates during this phase, and many patients begin to notice visible changes in body composition. Monthly physician check-ins confirm you are on the right track.
The 10mg dose represents a major step in Zepbound®'s efficacy profile. Many patients achieve their best results at this dose and find it to be their ideal maintenance level. Clinical data shows that most of Zepbound®'s weight loss benefit is captured by the time patients reach 10mg.
The 12.5mg dose is available for patients who are tolerating the medication well and wish to push toward maximum benefit. Your physician will evaluate whether escalating to this dose is appropriate based on your progress and overall health profile.
The 15mg weekly dose is the maximum approved dose of Zepbound® and was associated with the greatest weight loss in the SURMOUNT-1 clinical trial — an average of 22.5% body weight reduction over 72 weeks. Not every patient needs the maximum dose, and your physician will only recommend it if clinically appropriate.
Your Truventa physician will personalize your dose escalation. Many patients achieve their weight loss goals at 10mg without needing the maximum dose. Dose adjustments can always be slowed or paused if you experience side effects — there is no rush.
The first-ever direct clinical trial compared these two medications. The results were unambiguous.

In the first-ever head-to-head trial (SURMOUNT-5), Zepbound® patients lost 47% more weight than Wegovy® patients over 72 weeks. This was not a marginal difference — it was a landmark result that cemented Zepbound® as the most effective weight loss medication in clinical history.
