A few years ago, almost nobody had heard of a GLP-1 medication. Today they're everywhere — Ozempic, Wegovy, Mounjaro, Zepbound, all over your feed. And for good reason: they actually work.
At Medi-Slim Weight Loss & Spa, we've spent more than 22 years helping Las Vegas patients lose weight — long before GLP-1s became a household name. If you're curious about what these drugs are, how they work, and whether one might fit your situation, here's everything you need to know — minus the hype.
GLP-1 stands for glucagon-like peptide-1. It's a hormone your gut already makes every time you eat. It helps your body:
A GLP-1 medication is a drug that mimics this hormone. It's given as a weekly subcutaneous injection (small needle, quick pinch). The effect: you feel full sooner, you stay full longer, your cravings quiet down, and over months, the weight comes off.
Right now in the US, the major GLP-1 (and GLP-1-adjacent) medications for weight loss are:
Pure GLP-1 agonist. Brand names: Ozempic (for type 2 diabetes) and Wegovy (for chronic weight management). Clinical trials showed around 12–15% body weight loss over about a year.
Dual agonist — activates both GLP-1 and a second hormone called GIP. Brand names: Mounjaro (diabetes) and Zepbound (weight loss). Trials showed around 15–20% body weight loss. The dual mechanism is why tirzepatide tends to outperform pure GLP-1s on raw pounds.
At Medi-Slim Weight Loss & Spa in Las Vegas, we dispense compounded semaglutide and compounded tirzepatide. Same active ingredient as the brand names, prepared by a licensed compounding pharmacy. Same molecule, different supply chain.
These medications are generally appropriate for adults who:
They're not right for everyone. We won't prescribe a GLP-1 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 review your full picture before prescribing anything.

A pure GLP-1 (semaglutide) hits one receptor. A dual like tirzepatide hits two. The dual typically produces more weight loss on average.
No. Some are FDA-approved for type 2 diabetes (Ozempic, Mounjaro), others for weight management (Wegovy, Zepbound). Same active ingredients, different labels.
Trials showed 12–15% on semaglutide and 15–20% on tirzepatide over about a year. Your numbers depend on your starting point, dose, and consistency with habits.
GLP-1s have been used for type 2 diabetes for close to a decade, so there's real long-term data. For weight-loss-specific dosing, the safety picture is still developing, but favorable. Your provider will walk through the specifics during your consultation.
Yes — we see patients from across the valley.
