You've tried diets. You've tried the gym. The scale barely moves, or it moves and then bounces right back. If that sounds familiar, you're not alone — and you're in the right place.
At Medi-Slim Weight Loss & Spa in Las Vegas, we treat weight loss like the medical issue it is. One of the tools we use is compounded tirzepatide, a weekly injection that's been quietly changing the game for patients across Henderson, Summerlin, Spring Valley, and the rest of the valley.
This guide walks you through what tirzepatide actually is, how we use it, who it's for, and what your first few months might look like. No fluff. No fine print surprises.
Tirzepatide is a prescription medication that works on two hormones your body already makes: GLP-1 and GIP. Both hormones help regulate appetite and blood sugar. By activating both at once, tirzepatide does three useful things:
That combination is why patients on tirzepatide in clinical trials lost an average of 15–20% of their body weight. For someone who starts at 220 pounds, that's 33–44 pounds over the course of treatment.
You may have heard of Mounjaro or Zepbound — those are brand names for tirzepatide made by Eli Lilly. At MediSlim, we dispense compounded tirzepatide. It contains the same active ingredient and works the same way. The difference is how it's prepared: compounded medications are made by a licensed compounding pharmacy instead of a large drug manufacturer. We want to be upfront about that so you know exactly what you're getting.
We keep the process simple. Here's what happens after you reach out:
Our team handles your nutrition and lifestyle guidance in-house — we don't outsource that piece. You'll work directly with us from day one.
Tirzepatide works well for adults who:
It's not for everyone. We won't prescribe tirzepatide if you have a personal or family history of medullary thyroid cancer, a history of pancreatitis, multiple endocrine neoplasia syndrome type 2, severe gastrointestinal issues, or if you're pregnant or nursing. That's why the consultation matters — we'd rather be careful upfront than run into problems later.
Most patients see the scale start moving within the first 4–6 weeks. The biggest drops usually happen in months 3 through 6, as your dose is titrated up and your appetite changes settle in.
Side effects are usually mild and temporary. The most common ones are:
We manage all of this by starting you on a low dose, increasing slowly, and being reachable when something comes up. A few small changes — smaller meals, more water, cutting back on greasy food — usually handle the rest.
Tirzepatide gets you traction. Habits keep the weight off. We work with every patient on:
You don't need to be perfect. You need to be consistent. That's the whole game.

In clinical trials, patients lost an average of 15–20% of their starting body weight over about a year. Your results will depend on your starting point, your dose, and how consistent you are with the habit piece.
Most patients notice appetite changes within the first couple of weeks and start seeing the scale move by week 4–6. The biggest drops usually happen in months 3–6.
The active ingredient is the same. Mounjaro is the brand name made by Eli Lilly. At MediSlim we dispense compounded tirzepatide, which is prepared by a licensed compounding pharmacy. Same molecule, different supply chain.
It's a small, weekly injection with a short, thin needle — most patients find it easier than they expected. We walk you through it step by step. If you'd rather come in and have us do it, that works too.
