Tirzepatide vs Semaglutide: What the Clinical Trials Showed

What Are GLP-1 Medications & How Do They Work?

GLP-1 weight loss medications work by mimicking glucagon-like peptide-1, a hormone your gut naturally releases after eating. At therapeutic doses, these medications suppress appetite at the brain level, slow gastric emptying, improve insulin sensitivity, and reduce food cravings — producing weight loss that far exceeds what diet and exercise alone can achieve in most patients.

The two leading medications are semaglutide (Ozempic for diabetes, Wegovy for weight loss) and tirzepatide (Mounjaro for diabetes, Zepbound for weight loss). Tirzepatide is the newer, more effective option — it activates both GIP and GLP-1 receptors, producing a dual hormonal effect that consistently outperforms semaglutide in clinical trials.

Tirzepatide vs. Semaglutide: 2025 Clinical Data Compared

The SURMOUNT-1 trial (Jastreboff et al., NEJM 2022) demonstrated tirzepatide 15mg achieving 20.9% mean body weight reduction over 72 weeks — a result previously seen only with bariatric surgery. For a 250 lb patient, that’s approximately 52 lbs. The STEP-1 trial for semaglutide 2.4mg showed 14.9% reduction — still clinically significant, but meaningfully lower. Head-to-head data from SURMOUNT-5 confirmed tirzepatide produced 47% more weight loss than semaglutide at equivalent duration.

What Results Can You Realistically Expect?

Results depend on starting weight, metabolic health, adherence, protein intake, and exercise. Based on clinical trial data and real-world patient outcomes, here is a typical tirzepatide timeline:

Important: stopping the medication without a structured transition plan typically results in weight regain within 12 months.  Our program includes a maintenance protocol to preserve long-term results.

Who Qualifies for GLP-1 Weight Loss in Boca Raton?

FDA approval guidelines require a BMI of 30+ (obese) or BMI 27+ with at least one weight-related health condition — hypertension, Type 2 diabetes, high cholesterol, or sleep apnea. our physician evaluates each patient individually and may extend benefit to patients with BMI 25–27 with significant metabolic syndrome on a case-by-case basis.

Your initial consultation includes a comprehensive medical history review, current medications, lab panel, and discussion of your goals. This is a full clinical evaluation — not a quick prescription visit.

How Brazelia Med Spa’s GLP-1 Program Works

Every patient is managed by our team at Brazelia Med Spa — with experience in hormone optimization, metabolic medicine, and integrative wellness. Every protocol is individualized.

1. Initial Consultation + Labs: Comprehensive metabolic panel, HbA1c, thyroid, lipid panel, kidney/liver function, full hormone assessment.
2. Personalized Dosing: Slow titration protocol minimizes side effects and improves adherence.
3. Monthly Check-ins: Body composition, labs, appetite feedback, medication adjustments.
4. Nutritional Guidance: Protein optimization (0.8–1g/lb lean mass), micronutrient support, meal timing for muscle preservation.
5. Maintenance Planning: Structured weaning, habit consolidation, and continued metabolic support.

We prescribe the FDA-approved medications Zepbound and Wegovy where they are clinically appropriate for you following evaluation. Federal restrictions on compounding semaglutide and tirzepatide changed in 2025, and we do not offer compounded versions of these medications as a routine or lower-cost substitute for an available FDA-approved product.

Side Effects, Risks & How We Manage Them

The most common side effects are gastrointestinal — nausea, reduced appetite, loose stools. These are dose-dependent and typically resolve within 2–4 weeks of each dose increase. Our slow titration protocol is designed to minimize these.

Absolute contraindications: personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia type 2 (MEN2). Every patient is screened for these and other contraindications by a prescribing provider before any medication is started.

Costs & Compounded Options

Brand-name GLP-1 medications cost approximately $700–$1,350 per month before any insurance benefit or manufacturer savings program. Your actual cost depends on the medication prescribed, your dose, your pharmacy and your coverage, and is confirmed with you before treatment begins. Financing is available through CareCredit, an independent third-party lender on its own terms.

A note on compounded medications. Compounded drugs are not FDA-approved. FDA does not review them before marketing for safety, effectiveness or manufacturing quality, and a pharmacy being registered as a 503B outsourcing facility does not mean any drug it prepares is FDA-approved. Since 2025 semaglutide and tirzepatide are no longer in shortage and the compounding pathways available during the shortage have closed. Where a compounded preparation is used at all, it is only because a prescriber has determined and documented that an FDA-approved product is not clinically appropriate for that individual patient.
