If you have been following the next wave of weight-loss medicine, you have probably heard one name more than any other: retatrutide, the medication a lot of people now search for as a “GLP-3.” It is the most talked-about weight-loss medication in years, and for good reason. In early studies, people taking it lost more weight than with any injectable in wide use today. The natural next question is simple: where does it actually stand, and what should I be doing about my own goals right now?
Here is the encouraging part. You do not have to sit on the sidelines while this category evolves. The smartest patients are getting a head start now with a proven, physician-guided program, so they are already lean, already established with a trusted local team, and already ahead of the crowd. This guide walks through what retatrutide is, where retatrutide availability stands right now, and how to build momentum today at Franklin, TN and Nolensville, TN.
Retatrutide is a once-weekly injectable being developed as the next generation of weight-loss medication. What makes it special is that it works on three different hormone pathways at once, GIP, GLP-1, and glucagon, which is why it is nicknamed the “triple-G” or triple agonist. You may also see it called a “GLP-3” online. That is not an official drug class, but the nickname stuck because retatrutide reaches a step beyond the GLP-1 medications most people already know. Today’s leading medications act on one or two of these pathways. Retatrutide adds a third lever that also helps the body burn energy, not just reduce appetite.
The excitement is grounded in real results. In a 2023 phase 2 trial published in the New England Journal of Medicine, adults with obesity taking the highest dose of retatrutide lost an average of 24.2 percent of their body weight over 48 weeks, a level of weight reduction that had rarely been seen with medication alone. A separate phase 2 study in adults with type 2 diabetes, published in The Lancet, showed strong weight and blood-sugar improvements as well.
Retatrutide, the medication most people are searching for when they type “GLP-3,” is moving through a large phase 3 research program designed to confirm how well it works and how safely it performs over the long term. You can see the flagship study, which is enrolling thousands of participants, on the government registry for the TRIUMPH-1 phase 3 retatrutide trial.
This category is moving quickly, and what is appropriate for any one patient depends on their history, their goals, and their full medical picture. That is a conversation, not something a web page can answer. The most useful step is to sit down with our providers, review where your health stands, and let us walk you through which supervised option makes the most sense for you right now.
Retatrutide is the future, but the medications available right now are genuinely excellent and have helped millions of people transform their health. Semaglutide and tirzepatide, both offered at Body Works, deliver powerful, well-documented results, and you can start either one today under medical supervision.
In the SURMOUNT-1 trial in the New England Journal of Medicine, adults on the highest dose of tirzepatide lost an average of 22.5 percent of their body weight over 72 weeks. Earlier, the STEP 1 trial of semaglutide showed an average loss of nearly 15 percent. These are proven, available tools you can put to work immediately.
| Medication | How it works | Available today? |
|---|---|---|
| Semaglutide | Single pathway (GLP-1) | Yes, at Body Works |
| Tirzepatide | Dual pathway (GIP and GLP-1) | Yes, at Body Works |
| Retatrutide | Triple pathway (GIP, GLP-1, and glucagon) | Ask our providers |
The smartest move is to start now rather than pause your goals. Every month you spend closer to your target weight is a month of better energy, better health markers, and real momentum, and the habits and medical relationship you build today carry straight over to whatever comes next. As newer options reach patients, you will be in an even stronger position to benefit from them.
Starting with a supervised semaglutide or tirzepatide program also means you are working with a provider who understands how these medications work at the hormone level and how to keep your results safe and steady. Every medication we use is dispensed through licensed providers under the framework that governs which medications a pharmacy may prepare, described in the FDA’s compounding standards for pharmacies. Being an established patient means your provider can move quickly as your best option changes.
Body Works runs physician-supervised medical weight-loss programs built around your body, your history, and your goals, not a one-size-fits-all script. That means real medical oversight, dosing tailored to you, and a team that stays current on the science so you always know what your best options are, today and as the field evolves.
It also means local, in-person care. With offices in Franklin and Nolensville, you get a provider you can actually sit down with, plus support for building the habits that make results last. If retatrutide is on your radar, the best first step is a conversation. Schedule a Free Consultation and start your momentum now, with a team ready to guide you every step of the way.
