You've probably seen the headlines. Celebrities dropping 40 pounds. Before-and-after photos flooding your feed. And the word on everyone's lips: Mounjaro.
If you're in Las Vegas and wondering how to get on it, we want to be straight with you before you book anything. At Medi-Slim Weight Loss & Spa, we don't dispense brand-name Mounjaro. We dispense compounded tirzepatide — the same active ingredient, prepared by a licensed compounding pharmacy. Here's why that distinction matters, and what your path with us actually looks like.
One thing worth knowing up front: MediSlim has been doing weight-loss medicine in Las Vegas since before GLP-1s were a household word — 22+ years and counting. So while compounded tirzepatide is the newest tool in our toolbox, the clinic isn't new to this. We've seen the long arc of weight-loss medicine and we know what works.
Mounjaro is Eli Lilly's brand name for tirzepatide, a once-a-week injection that activates two gut hormones — GLP-1 and GIP — at the same time. Zepbound is the same drug marketed for weight loss specifically. Both are manufactured by Eli Lilly.
Tirzepatide works in three simple ways:
In clinical trials, patients lost an average of 15–20% of their body weight on tirzepatide. For someone starting at 220 pounds, that's 33–44 pounds over the course of treatment.
We want to be upfront so there are no surprises. When you come to MediSlim, we are not giving you the Eli Lilly-branded Mounjaro pen you might have seen in ads. We dispense compounded tirzepatide, which is the same molecule prepared by a licensed compounding pharmacy.
What compounding means: a licensed pharmacy prepares the medication in-house rather than manufacturing it at scale. The active ingredient is identical. What changes is the supply chain and the delivery format.
We take this approach because it keeps treatment accessible for patients who either can't get the brand-name drug through a retail pharmacy or who'd rather work with a clinic that handles everything in one place. If you'd rather have the brand-name product, we'll tell you where to go. If the compounded equivalent is right for you, we'll get you started.
We keep the process simple:
Our team handles the nutrition and lifestyle guidance directly.
Tirzepatide is generally appropriate for adults who:
It's not for everyone. We won't prescribe it 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.
Most patients see the scale move within the first 4–6 weeks. As your dose is titrated up and your appetite settles into its new pattern, weight loss tends to become steadier — though the exact pace varies patient to patient.
Common side effects are mild and temporary:
We manage all of this by starting you low, titrating slowly, and being reachable when something comes up.
Medi-Slim Weight Loss & Spa is in Las Vegas and serves patients from Henderson, Summerlin, Spring Valley, North Las Vegas, and the surrounding areas.

Active ingredient is the same. Mounjaro is Eli Lilly's brand-name product; compounded tirzepatide is prepared by a licensed compounding pharmacy. Same molecule, different preparation and supply chain.
Brand-name Mounjaro runs through a retail pharmacy supply chain that we don't control. Compounding lets us dispense directly to our patients without those bottlenecks. If the brand-name product is a better fit for you for any reason, we'll tell you.
No. We're a cash-pay clinic. Pricing is transparent and discussed at your consultation.
Clinical trials showed an average of 15–20% of body weight over about a year. Your results depend on your starting point, your dose, and how consistent you are with the habit piece.
Weekly injections can happen at home or at the clinic. Follow-up visits are scheduled based on where you are in treatment — more frequent at the start, less often once you're stable.
Yes — we see patients from across the valley. Book a consultation and we'll handle the rest.
