The Mounjaro Real-World Survey

What's this all about?

We're creating the largest community-led survey on Mounjaro (tirzepatide) to better understand real-life experiences.

Clinical trials for Mounjaro have varied in size, with some involving large participant groups:

• SURPASS-2 Trial: A 40-week, phase 3 study with 1,879 patients, comparing different doses of tirzepatide to semaglutide.
• SURMOUNT-3 Trial: Focused on weight loss, this trial involved 806 participants who had completed a prior lifestyle intervention.

In contrast, user-generated reviews and smaller surveys have gathered insights from individual experiences:

• WebMD User Reviews: Features 606 user ratings and reviews for Mounjaro, providing personal accounts of effectiveness and side effects.

However, real-world usage far exceeds these studies. As of December 2024, an estimated 500,000 people in the UK were using weight-loss medications like Mounjaro and Wegovy through private prescriptions. Mounjaro has been the more popular choice, making up about 70% of sales in some online pharmacies.

Additionally, the UK’s National Institute for Health and Care Excellence (NICE) recently approved Mounjaro for NHS prescriptions for those with a BMI over 35 and at least one weight-related condition. While an estimated 3.4 million people in England qualify, the initial NHS rollout will only reach 220,000 people over the next three years.

This means that while thousands are already experiencing the effects of Mounjaro, most real-world experiences remain undocumented.

We want to hear directly from you—the everyday users—to gather honest insights about side effects, emotional impacts, and personal journeys that clinical studies might miss.

Who can participate?

If you’re currently using Mounjaro, we’d love to hear from you! Whether you’ve just started or have been on it for months, your experience matters. The more diverse our participants, the more complete and insightful our findings will be—helping others set realistic expectations and navigate their own journeys with confidence.

We need your help to make this the most extensive Mounjaro user survey ever! Share this survey with as many people as possible—friends, support groups, and online communities. The more responses we collect, the more powerful and impactful this survey will be!

Is this a scientific or medical study?

No, this isn’t a clinical trial or formal medical research—it’s a community-driven survey designed to gather real-life experiences from Mounjaro users. While clinical trials are essential, they can’t always capture the full picture of what it’s like to use the medication day-to-day. That’s where your input comes in! Your responses will help paint a more realistic view of how Mounjaro affects people beyond controlled studies. However, this and any associated published findings are not medical advice, and we always encourage speaking with a healthcare professional for any personal health concerns.

Is my information anonymous?

Absolutely. Your privacy is paramount. This survey is designed to collect data anonymously, ensuring that individual identities remain completely confidential and secure. We do not collect personal identifiers such as your name, email, or specific medical information.

How will the results be used?

The anonymous data collected from this survey will be carefully analyzed to uncover trends, patterns, and shared experiences among Mounjaro users. Our goal is to present these findings back to the community—not only to provide a clearer understanding of how Mounjaro works in real life, but also to motivate and inspire others on their journey.

By identifying key trends—such as common weight loss timelines, side effects, emotional impacts, and success stories—we can help new users set realistic expectations and empower those considering Mounjaro to make informed decisions. These insights will be shared through our blog, social media, and community discussions, ensuring that everyone benefits from the collective knowledge of real users.

Additionally, as the study grows, we’ll explore topics like lifestyle changes, weight loss maintenance, and any unexpected benefits or challenges users face. This isn’t just about gathering data—it’s about building a strong, informed, and supportive Mounjaro community where experiences can be shared, discussed, and learned from.

How can I help?

Your participation is essential in making this survey as impactful as possible. By taking just a few minutes to complete the survey, you're contributing to a greater understanding of Mounjaro’s real-world effects—helping others set realistic expectations, prepare for potential challenges, and celebrate their progress along the way.

But it doesn’t stop there! We need your help to spread the word and reach as many Mounjaro users as possible. The more responses we collect, the clearer the picture we can build. Please consider sharing this survey with your social media communities, weight loss forums or in conversations with friends and family using Mounjaro.

Every shared experience adds to the bigger picture, making this study stronger and more meaningful. Together, we can create the most comprehensive collection of real-world Mounjaro experiences—helping to support, motivate, and guide others on the same journey.

Thank you for being part of this important initiative! Your voice matters, and we appreciate every response.
