Each of these therapies represents a major advancement in the science of metabolism and body composition.

The Rise of GLP-1 and Incretin-Based Weight Loss Therapies

Medications like Semaglutide, Tirzepatide, and Retatrutide belong to a class of treatments designed to improve metabolic function by mimicking natural gut hormones called incretins. These hormones help regulate appetite, energy use, and blood sugar levels — and when optimized, they can lead to significant fat loss and improved health markers.

At Renovo Health and Beauty, our medical team stays ahead of global medical trends to bring safe, effective, and innovative treatments to our patients. Because we operate in Tijuana, we have more flexibility in customizing treatment protocols and greater accessibility to emerging therapies that may not yet be available in the United States.

Understanding Each Medication

Semaglutide

Semaglutide is one of the most established medications in this class. It works by mimicking GLP-1 (glucagon-like peptide-1), a hormone that signals fullness, slows digestion, and helps regulate insulin production.

It is widely recognized under brand names like Ozempic, Rybelsus, and Wegovy, and it’s FDA-approved for both type 2 diabetes and chronic weight management. Patients around the world have achieved remarkable results using Semaglutide, especially when combined with proper nutrition and physical activity.

FDA Status: Approved for both diabetes and weight management

Mechanism: GLP-1 receptor activation that reduces appetite and improves blood sugar balance

Average Weight Loss: 10–15% of total body weight

Side Effects: Mild digestive upset, nausea, or constipation (usually temporary)

At Renovo Health and Beauty, Semaglutide can be administered as part of a personalized weight loss plan designed to fit your goals and lifestyle — often at a fraction of the cost of U.S.-based treatments.

Tirzepatide

Tirzepatide represents a significant step forward in incretin-based therapy. Unlike Semaglutide, Tirzepatide acts on two different receptors — GLP-1 and GIP (glucose-dependent insulinotropic polypeptide). This dual action enhances its ability to regulate blood sugar and appetite while improving how the body stores and uses fat.

Tirzepatide is sold under the brand names Mounjaro (for diabetes) and Zepbound (for weight loss), both of which are FDA-approved. Studies have shown that Tirzepatide can produce even greater average weight loss than Semaglutide, along with improved insulin sensitivity and metabolic control.

FDA Status: Approved for type 2 diabetes and obesity treatment

Mechanism: Dual GLP-1 and GIP receptor activation for enhanced metabolic response

Average Weight Loss: 18–22% of total body weight

Side Effects: Nausea, occasional fatigue, or mild gastrointestinal symptoms

At our Tijuana clinic, patients who qualify for Tirzepatide can enjoy greater affordability and individualized dosing options, without the high cost or wait times often experienced at clinics in the United States.

Retatrutide

Retatrutide is the newest and most advanced incretin-based therapy currently being studied. It acts on three different receptors — GLP-1, GIP, and glucagon receptors — giving it the potential to enhance fat metabolism, improve blood sugar control, and increase energy expenditure simultaneously.

In early clinical studies, Retatrutide demonstrated unprecedented results, with participants achieving up to 24% reductions in body weight. However, as of 2025, Retatrutide has not yet received FDA approval, and its commercial availability in the U.S. remains limited.

FDA Status: Not yet approved (undergoing clinical trials)

Mechanism: Triple hormone receptor activation (GLP-1, GIP, and glucagon) for enhanced fat loss and metabolic balance

Average Weight Loss: Up to 24% reported in clinical trials

Side Effects: Mild nausea, fatigue, or digestive sensitivity

At Renovo Health and Beauty, our international setting allows us to explore innovative therapies like Retatrutide sooner than many U.S.-based clinics, offering patients early access opportunities when appropriate and permitted under Mexican medical guidelines.

Why Choose Renovo Health and Beauty in Tijuana

One of the greatest advantages of seeking treatment at Renovo Health and Beauty is affordability. In the U.S., GLP-1 and GIP-based medications can cost hundreds or even thousands of dollars per month — often not covered by insurance.

In Mexico, the same or similar high-quality medications are often available at a fraction of the price, without compromising safety or quality. Our team works with licensed physicians, pharmacists, and international suppliers to ensure that patients receive safe, authentic treatments tailored to their health profile.

Beyond affordability, we also enjoy greater flexibility in our treatment protocols, allowing our physicians to customize dosing schedules and combination therapies that align with your body’s unique needs. This individualized approach often leads to improved results and better overall tolerance of the medication.

At Renovo Health and Beauty, we take pride in offering an experience that combines modern medical expertise with compassionate, personalized care — all within a comfortable, patient-centered environment.

The Role of FDA Approval and International Access

While FDA approval is the gold standard for medication regulation in the United States, many therapies achieve recognition abroad years before they’re available domestically. This often creates a delay for American patients seeking the latest advancements in regenerative and metabolic medicine.

Operating in Tijuana allows Renovo Health and Beauty to bridge this gap. We adhere to rigorous international safety standards while offering access to cutting-edge treatments that may not yet be widely available north of the border.

This unique position gives our patients access to a broader range of options, especially for those seeking innovative or cost-effective alternatives to traditional U.S. medical care.

FAQs About Retatrutide, Tirzepatide, and Semaglutide

Retatrutide is still under clinical review and not yet FDA-approved. However, our medical team monitors ongoing international developments closely and can advise patients when it becomes available under Mexican or global guidelines.

Tirzepatide activates two hormones — GLP-1 and GIP — making it more potent for both appetite control and fat metabolism. Semaglutide targets only GLP-1, but still delivers excellent results.

Patients often save 40–70% on weight loss treatments in Mexico compared to U.S. prices, even when factoring in travel. Renovo offers transparent pricing and professional medical care at exceptional value.

Yes. Semaglutide and Tirzepatide are well-studied and FDA-approved. Retatrutide is still under evaluation but has shown encouraging safety data in ongoing trials.

Absolutely. Both Semaglutide and Tirzepatide are approved for weight management in adults with obesity or weight-related conditions, regardless of diabetes status.

Beyond cost savings, Mexico offers more flexible medical guidelines that allow for customized treatment plans, often with less red tape and faster access to emerging therapies.
