Weight loss injections — specifically GLP-1 and GIP-based medications — have genuinely changed what's possible for patients who'd been fighting their weight for years. If you're in Las Vegas and trying to figure out which one is right for you, here's what you actually need to know.
At Medi-Slim Weight Loss & Spa, we dispense compounded Semaglutide and compounded Tirzepatide, both administered weekly.
For some context: MediSlim has practiced weight-loss medicine in Las Vegas for over 22 years. The injections are recent; the clinic isn't.
Both medications mimic gut hormones your body already makes. Those hormones do three useful things:
Tirzepatide hits two of those hormones (GLP-1 and GIP). Semaglutide hits one (GLP-1). Tirzepatide tends to produce slightly more weight loss in head-to-head studies.
Short version:
Either is a real tool. The right one for you depends on your starting point, your goals, how your body tolerates the medication, and your budget. We figure that out at the consultation — we don't default-prescribe one over the other.
We dispense compounded semaglutide and tirzepatide — not the brand-name Ozempic, Wegovy, Mounjaro, or Zepbound pens. Compounded medications are prepared by a licensed compounding pharmacy using the same active ingredient. The molecule is identical; the preparation and supply chain are different.
We're upfront about this so nobody is surprised. If you'd specifically prefer a brand-name product, we'll tell you where to look.
Nutrition and lifestyle guidance is handled in-house by our team.
Generally a fit for adults who:
We rule it out 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 are pregnant or nursing.
Most patients notice appetite changes within the first couple of weeks. The scale usually starts moving by week 4–6. Most patients see steadier weight loss as their dose is titrated up over the first several months — though the exact pace varies patient to patient.
Common side effects are mild and usually temporary — nausea, mild stomach upset, reduced appetite. We manage this by starting low, going slow, 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. Consultations are paid and by appointment — we don't work with insurance.
Most patients are surprised at how easy the injection is — short, thin needle, subcutaneous. We teach you how, or you can come in and have us do it.
Same active ingredients. Ozempic and Wegovy are brand-name semaglutide; Mounjaro and Zepbound are brand-name tirzepatide. We dispense compounded versions prepared by a licensed compounding pharmacy.
Clinical trials showed about 12–15% on semaglutide and 15–20% on tirzepatide over a year. Your numbers depend on your starting point, dose, and consistency.
No. We're cash-pay. Transparent pricing discussed at your consultation.
Weekly injections can happen at home. Follow-ups are more frequent early on (during dose titration) and less often once you're stable.
Yes — we see patients from across the valley.
