GLP-1 Weight Loss Therapy

GLP-1 weight loss injections — safely prescribed in Mesquite.

GLP-1 receptor agonists have transformed medical weight loss over the past several years. At Regal Weight Loss in Mesquite, we've been prescribing GLP-1 therapy under medical supervision since the very beginning of the GLP-1 era — well before these medications became household names. Our chief consultant Marissa works closely with our medical director, Dr. Eric Naifeh, to make sure every GLP-1 protocol is appropriate for the patient in front of her.

How GLP-1 medications work

GLP-1s mimic a hormone your body naturally produces after eating. They slow gastric emptying (helping you feel full longer), reduce appetite signals to the brain, and improve insulin sensitivity. There are several different GLP-1 protocols available today, each with different mechanisms and dosing approaches — and no two patients respond identically. That's why Dr. Naifeh personally evaluates your labs, medical history, and goals before prescribing any specific GLP-1 protocol.

Why getting GLP-1s at a medical weight loss clinic matters

The market is flooded with online services that will ship GLP-1 medications to your door with little more than a brief intake form. The problem with that model isn't the medications themselves — it's everything missing around them:

  • Proper dosing. Starting at the wrong dose, escalating too fast, or staying flat too long all sabotage results and increase side effects.
  • Lab work and medical review. Underlying conditions (thyroid issues, insulin resistance, nutritional deficiencies) can dramatically affect your response — and need to be identified before you start.
  • Nutritional foundation. If you don't change how you eat, the medication will stop working, you'll plateau, or you'll regain everything when you stop. This is the well-documented GLP-1 rebound phenomenon.
  • Real accountability. Weekly check-ins, protocol adjustments, side effect management — none of which a mail-order pharmacy provides.
The key insight: The medication is a tool. The plan around it is what produces lasting results. At Regal, you get both.

What to expect at your first GLP-1 evaluation

Every new patient pursuing GLP-1 therapy at our Mesquite clinic completes a full medical intake, baseline lab work, and a one-on-one consultation with Marissa, our chief consultant and certified nutritionist. Dr. Eric Naifeh, our medical director, reviews your labs and history before any medication is prescribed. Once cleared, you'll receive your customized starting protocol with dosing, scheduling, supply guidance, and a nutritional foundation to work from.

Weight Loss Injections

Lipotropic shots, LipoStat, and B12 — the supporting cast that matters.

Not every weight loss patient is a GLP-1 candidate, and even those who are often benefit from supportive injections. Our Mesquite clinic offers a full range of lipotropic weight loss injections, B12 shots, and our proprietary LipoStat skinny shot — designed to support fat metabolism, energy, and overall wellness.

What are lipotropic injections?

Lipotropic injections — sometimes called "MIC injections" — contain a combination of compounds that help your liver process and metabolize fat more efficiently. The classic formulation includes methionine, inositol, and choline (the "MIC"), often combined with B-vitamins for energy support. Many patients receive these injections weekly as part of an ongoing weight loss program, either alongside GLP-1 therapy or as a standalone protocol.

The LipoStat Skinny Shot

The LipoStat skinny shot is our proprietary lipotropic formulation, enhanced with additional fat-burning compounds and B12 for energy. Many of our Mesquite patients use LipoStat as their primary weight loss injection when they're not on GLP-1s, or as a complement to their GLP-1 protocol for added metabolic support.

B12 injections for energy and metabolism

Vitamin B12 plays a critical role in energy metabolism, nerve function, and red blood cell formation. Many adults — especially those on weight loss protocols — benefit from supplemental B12 injections to combat fatigue, support metabolism, and maintain energy levels during caloric restriction.

Who should consider weight loss injections?

Weight loss injections are appropriate for:

  • Patients who can't take or don't want GLP-1 medications
  • GLP-1 patients looking for additional metabolic and energy support
  • Anyone experiencing fatigue or low energy during weight loss
  • Patients in a maintenance phase looking to support their results
  • Clients who prefer a lower-cost alternative to GLP-1 therapy
Appetite Suppressants

Phentermine and beyond — FDA-approved tools for short-term support.

Phentermine has been an FDA-approved appetite suppressant for over 60 years and remains one of the most widely prescribed weight loss medications in the United States. At our Mesquite clinic, we offer phentermine and other clinically appropriate appetite suppressants as part of a structured medical weight loss program — never as a standalone solution.

How phentermine works

Phentermine works on the central nervous system to reduce hunger and increase satiety, making it easier to maintain a calorie deficit while you're building new eating habits. It's typically prescribed for short-term use (12 weeks or less) and works best when combined with nutritional coaching and lifestyle change.

Who is phentermine for?

Phentermine is appropriate for patients with a BMI of 30 or higher (or 27+ with weight-related health conditions) who don't have contraindications such as uncontrolled high blood pressure, history of heart disease, hyperthyroidism, or glaucoma. Dr. Naifeh reviews your medical history and labs to determine candidacy before prescribing.

Phentermine vs. GLP-1: which is right for you?

This is one of the most common questions we hear in Mesquite. The honest answer: it depends on your goals, medical history, budget, and timeline. Phentermine tends to be lower-cost, fast-acting, and best suited for short-term use. GLP-1 therapy tends to produce larger long-term weight loss, has additional metabolic benefits, and can be sustained for longer periods. Some patients use both at different phases of their weight loss journey. We'll help you figure out what fits your situation during your free consultation.

Appetite suppressants are tools — not cures. They work best when paired with the nutritional coaching and accountability that the Regal Membership provides.
Certified Nutritional Counseling

The foundation under everything else we do.

If we had to point to one thing that separates Regal Weight Loss from every "ship-the-meds-and-disappear" service that's popped up in DFW over the past few years, it would be this: nutrition coaching is the foundation, not an afterthought.

Why nutrition is non-negotiable

Every medication we offer — GLP-1 therapy, phentermine, lipotropic shots — is a tool that helps you eat less, burn more efficiently, or feel fuller. None of them teach you how to eat. And if you don't change how you eat, here's what happens: you take the medication, you lose some weight, you plateau or eventually stop the medication, and the weight comes back. Often more of it. This is the GLP-1 rebound effect that has become almost cliché in the medical weight loss world.

What working with Marissa actually looks like

Our chief consultant, Marissa, is a certified nutritionist who has guided hundreds of clients across the DFW area. She doesn't hand you a printed meal plan and wish you luck. The work is built around understanding:

  • What you actually eat now — and why
  • Your schedule, your food preferences, your family situation
  • Your goals (rapid loss, sustainable loss, maintenance, performance)
  • Your history with diets, medications, and lifestyle change
  • The specific obstacles that have tripped you up before

From there, Marissa builds a plan that's actually feasible for your life — not a copy-paste template. The plan adjusts as your results, schedule, and goals evolve. That's why our clients stay, and why their results last.

Nutrition for GLP-1 patients specifically

GLP-1 medications reduce appetite — sometimes dramatically. That sounds great, but it creates a problem most patients aren't warned about: protein intake drops, muscle mass declines, and metabolic rate drops with it. A patient losing 30 pounds on GLP-1 therapy without nutritional guidance is often losing far more muscle than they should, which makes the inevitable plateau worse and the rebound worse. Working with a nutritionist while on GLP-1s is what protects your long-term metabolic health.

Our membership model

The Regal Membership — everything we do, in one program.

After nearly a decade of building custom weight loss programs for DFW clients, we've launched a streamlined membership that bundles everything we've learned matters most — for one flat monthly fee. Currently piloted at our Mesquite location.

Most weight loss services today operate like a vending machine. You click, you pay, the meds arrive in a box. That's not us — and frankly, that's not really weight loss. It's a transaction with a side of hope.

The Regal Membership is built on a different idea: real coaching, real medical oversight, and real nutrition guidance are the actual product. The medications are powerful tools we use to maximize your results, but tools without a plan are why most people fail.

For $150/month with a 3-month minimum, members get everything that matters — custom plan, lab work, medical evaluation by Dr. Naifeh, weekly check-ins with Marissa, 24/7 AI support, and exclusive 25% pricing on every medication, peptide, injection, and supplement we offer. Plus free shipping and supplies.

Non-members can still purchase from us at standard pricing, but it costs more and includes none of the coaching infrastructure that actually produces results.

Frequently asked questions

The questions most Mesquite patients ask first.

If you don't see your question answered below, give us a call at (866) 580-6863 or visit our complete Mesquite FAQ page for more.

What is medical weight loss and how is it different from a regular diet program?
Medical weight loss is a physician-supervised program that combines clinical evaluation, lab work, prescription medications when appropriate (such as GLP-1 injections, appetite suppressants, or lipotropic shots), and structured nutritional coaching. Unlike commercial diet programs (Weight Watchers, Noom, etc.), a medical weight loss clinic like Regal Weight Loss can prescribe and monitor FDA-approved medications, review lab work for underlying conditions affecting weight, and customize protocols based on your medical history. The result is generally faster, larger, and more sustainable weight loss for clinically appropriate candidates.
Where can I get GLP-1 weight loss medications in Mesquite, TX?
Regal Weight Loss in Mesquite, TX offers medically supervised GLP-1 weight loss therapy. Our medical director, Dr. Eric Naifeh, reviews your lab work and medical history before any prescription is written. Through the Regal Membership, GLP-1 medications are available at exclusive member pricing — 25% lower than non-member rates — with free shipping and supplies included. Call (866) 580-6863 or text (469) 496-8980 to see if you qualify for a free consultation.
How much do weight loss injections cost in Mesquite?
Pricing for weight loss injections varies based on the medication (GLP-1, lipotropic, B12), dose, and whether you're a Regal Member. The Regal Membership is $150/month with a 3-month minimum, which includes your medical evaluation, lab work, and ongoing coaching — plus 25% off all medications, free shipping, and free supplies (syringes, alcohol wipes, reconstitution solution). Non-members pay standard pricing plus shipping. Exact pricing for your specific protocol is provided during your free consultation.
Who is the best weight loss doctor near Mesquite, TX?
Regal Weight Loss has been the medical weight loss leader in the Mesquite and Dallas-Fort Worth area since 2016. Our medical director, Dr. Eric Naifeh, oversees all clinical protocols, while certified nutritionist Marissa provides one-on-one coaching. We hold a 4.9-star Google rating across 124+ reviews and have guided hundreds of DFW patients through GLP-1 therapy, lipotropic injections, and lifestyle change.

What is the Regal Membership and what's included?
The Regal Membership is our coaching-led weight loss program.

Do I have to be a member to buy weight loss medications from Regal?
No. Non-members can still purchase medications and products, but at standard pricing (approximately 25% higher than member rates), plus shipping and supply costs. Members get exclusive lower pricing, free shipping, free supplies, included coaching, weekly check-ins, lab work, and medical evaluation. For most people losing weight long-term, the membership is significantly more economical and more effective than non-member purchases.
Does insurance cover medical weight loss at Regal?
We don't process insurance directly. However, we provide receipts (superbills) that you may submit to your insurance for possible reimbursement. Many flexible spending accounts (FSA) and health savings accounts (HSA) also accept Regal Weight Loss expenses. We'll discuss payment and reimbursement options during your free consultation.
Which GLP-1 protocol is right for me?
There are several GLP-1 receptor agonist protocols available today, each with different mechanisms, dosing approaches, and clinical considerations. Some are single-receptor agonists; others target multiple receptors and may produce different response profiles. Rather than guess, Dr. Naifeh reviews your lab work, medical history, current medications, and weight loss goals during your free consultation to determine which GLP-1 protocol fits your specific situation. There's no one-size-fits-all answer — that's why the consultation matters.
How long does it take to see results with medical weight loss?
Most patients begin seeing measurable results within the first 4–6 weeks. With GLP-1 therapy combined with nutritional coaching, average weight loss is typically 1–2 pounds per week, though individual results vary based on starting weight, adherence, medication response, and lifestyle factors. The 3-month Regal Membership minimum is designed around this timeline — giving members enough time to establish habits, see measurable progress, and adjust their protocol as needed.
Will I gain the weight back if I stop the medication?
Possibly — and this is exactly why nutrition coaching matters. The GLP-1 rebound effect is a well-documented phenomenon: patients who lose weight purely on medication, without changing their eating habits or lifestyle, often regain the weight (and sometimes more) when they stop. This is why the Regal Membership leads with nutritional counseling, accountability, and behavioral change — so the weight loss is sustainable beyond the medication.
What is the HCG diet and do you still offer it?
The HCG protocol — sometimes called the Dr. Simeons protocol — is a structured weight loss program combining HCG hormone with a specific low-calorie nutritional protocol. Regal Weight Loss has offered the HCG protocol since our founding in 2016, and we continue to offer it for clients who prefer a non-GLP-1 approach or who have had success with HCG in the past. Like all our protocols, it includes medical oversight and nutritional guidance.
Can we meet virtually if I'm not local to Mesquite?
Yes. Many clients combine in-person and virtual sessions based on schedule and location. Virtual consultations are available for clients anywhere in Texas. The conversation, the plan, the medical oversight, and the results don't change — just the location.
Is the first consultation really free?
Yes — completely free, no obligation to enroll. If you qualify and we schedule a consultation, there's no charge and no pressure to sign up afterward. Many people use the consultation to ask questions and decide later. That's perfectly fine.
What does "see if I qualify" actually mean?
It means we review your application to make sure the Regal Membership is the right fit — based on your goals, health history, and whether what we offer matches what you actually need. If we're a good match, we'll schedule a free 30-minute consultation with no obligation to enroll. The membership isn't for everyone, and we'd rather tell you that upfront than waste your time.
