Mounjaro
(Tirzepatide)

Mounjaro is the first-ever dual GIP and GLP-1 receptor agonist, developed by Eli Lilly. By activating two incretin hormone pathways simultaneously, it outperforms single-receptor GLP-1 drugs in clinical trials — achieving up to 22.5% body weight reduction in the landmark SURMOUNT-1 study.

It works by reducing appetite, slowing gastric emptying, improving insulin sensitivity, and increasing energy expenditure — a multi-pronged metabolic approach that no single-receptor drug can replicate.

All Mounjaro pens at MedEx are sourced exclusively through Zuellig Pharma — Asia's leading licensed pharmaceutical distributor — ensuring verified authenticity and full cold-chain traceability.

Understanding the Science Behind Each Pen

All three medications belong to the incretin mimetic class — they mimic naturally occurring gut hormones that signal fullness to the brain. But they differ significantly in mechanism, potency, and clinical outcomes.

GLP-1 (Glucagon-Like Peptide-1) slows gastric emptying, reduces appetite signals in the hypothalamus, and improves insulin secretion after meals. Semaglutide (Ozempic / Wegovy) targets this pathway.

GIP (Glucose-Dependent Insulinotropic Polypeptide) is a second incretin hormone that works synergistically with GLP-1. Tirzepatide (Mounjaro) activates both GIP and GLP-1 receptors — producing greater weight loss and metabolic improvements than either pathway alone.

Beyond appetite control, these medications also reduce chronic inflammation, improve lipid profiles, lower blood pressure, and provide meaningful cardiovascular protection — making them true metabolic therapies, not just weight loss drugs.

Medication Mechanism Max Dose Avg Weight Loss
MounjaroDUAL GIP + GLP-1 15 mg (10 mg at MedEx) Up to 22.5%
WegovyGLP-1 GLP-1 2.4 mg ~15%

Data from SURMOUNT-1 (Tirzepatide), STEP-1 (Semaglutide 2.4mg) and SUSTAIN-6 (Semaglutide 1.0mg) trials. Individual results vary.

Frequently Asked Questions

Do I need a doctor’s consultation before buying?

Yes, a medical screening is mandatory for safety and regulatory reasons. After placing your order, you will complete a health questionnaire that is reviewed by our licensed medical team to ensure Wegovy, Mounjaro, or Ozempic is appropriate for your specific health profile.

Who should not use Wegovy, Ozempic, or Mounjaro?

You should not use these medications if you have a personal or family history of medullary thyroid carcinoma (MTC) or MEN 2 syndrome. Always consult your doctor if you have a history of pancreatitis, kidney disease, or severe gastrointestinal conditions.

What is dose titration and why is it important?

Dose titration means starting at a low dose and gradually increasing it every 4 weeks. This allows your body to build tolerance and significantly reduces common side effects such as nausea or digestive discomfort. For Wegovy, this typically follows a 5-step process up to 2.4mg.

What are the common side effects?

Common side effects include nausea, bloating, diarrhea, constipation, or mild fatigue. These are usually temporary and most noticeable during the initial titration phase or when moving to a higher dosage.

Are these injections painful?

No. Wegovy, Ozempic, and Mounjaro use ultra-fine needles designed for comfortable, subcutaneous self-injection. Most users report little to no discomfort during the process.

How long does it take to see results?

Many patients notice reduced appetite within 1–2 weeks. Visible weight loss usually starts within the first month, with the most significant clinical results achieved over a 6–12 month treatment course.

How long should I stay on the medication?

Most treatment plans last between 6 and 12 months for steady weight reduction. Your doctor may recommend a maintenance phase once your target weight is reached to ensure long-term metabolic health.

What is the difference between Wegovy, Ozempic, and Mounjaro?

Ozempic and Wegovy both use Semaglutide, but Wegovy is approved at higher dosages specifically for weight loss. Mounjaro (Tirzepatide) is a dual-receptor agonist (GIP/GLP-1), which generally results in the highest percentage of weight reduction.

Are the medications original and authentic?

Yes. All products are sourced from licensed pharmaceutical distributors in Thailand (Novo Nordisk and Eli Lilly) and include verifiable batch numbers and expiry dates.

Is cold-chain delivery really necessary?

Absolutely. These peptide medications must be stored between 2°C and 8°C to remain stable. MedEx uses medical-grade cold-chain packaging to ensure the medication remains effective from our facility to your doorstep.

Can tourists buy Wegovy or Mounjaro in Thailand?

Yes. Tourists can legally purchase these medications through MedEx following medical approval. We provide discreet delivery to hotels and serviced apartments across Thailand, along with medical certificates for international travel.
