In recent years, the name “Mounjaro” or Tirzepatide has gained significant attention among those seeking safe and effective weight loss solutions—especially individuals struggling with obesity, insulin resistance, or prediabetes. Although originally developed as a treatment for Type 2 diabetes, its “side effect” of reducing appetite and promoting substantial weight loss has made it highly popular for off-label use.
But this growing interest has raised many important questions, such as:
- Where can I buy Mounjaro in Thailand?
- Can I inject it myself at home?
- How does it compare with Ozempic or Saxenda?
- When will I see results?
- How can I avoid fake products?
This article gathers the most frequently searched questions (FAQs) about Mounjaro in Thailand and provides clear, doctor-approved answers to help you make informed decisions.
Where can I buy Mounjaro in Thailand?
As of 2025, Mounjaro has been approved by the Thai FDA and is available only at authorized anti-aging or metabolic clinics with close medical supervision. It is not sold over-the-counter or in general pharmacies. Patients must be evaluated and prescribed the medication by a certified physician.
Clinics where Mounjaro is available:
- Siam Clinic – Ko Kaew Branch, Phuket
- Siam Clinic – Chalong Branch, Phuket
Do I need a prescription to buy Mounjaro?
✅ Yes. Mounjaro is a controlled medication and requires a doctor’s prescription. Physicians will assess your:
- BMI
- Blood sugar and liver enzymes
- Fatty liver status
- Kidney function and overall suitability
Can I buy Mounjaro online? (Shopee, Lazada, Line)
❌ Strongly discouraged.
Online platforms such as Shopee, Lazada, or social media often sell counterfeit or expired products without medical supervision.
💡 Fake pens may contain ordinary fluid and can be life-threatening if injected.
📌 Red flag: Prices under 10,000 THB without medical oversight are likely too good to be true.

Why must Mounjaro be prescribed and purchased from a clinic?
Because Mounjaro belongs to the GLP-1/GIP receptor agonist drug class, affecting blood sugar, insulin, and central appetite regulation. Incorrect usage can lead to serious side effects such as:
- Nausea or vomiting
- Hypoglycemia (low blood sugar)
- Pancreatitis
- Irregular heartbeat
✅ Medical supervision ensures proper dosing and side effect monitoring.
What is the price of Mounjaro in Thailand?

|---|---|---|
| 2.5 mg | 9,900–12,000 THB | ~10,000 THB |
| 5.0 mg | 12,000–14,500 THB | ~13,000 THB |
| 10–15 mg | 15,000–19,000 THB | ~17,000–20,000 THB |
How is Mounjaro injected? Arm or thigh?
Mounjaro is a weekly subcutaneous injection (under the skin), using an auto-injector pen. Common injection sites include:
- Abdomen (avoid area too close to the navel)
- Front of the thigh
- Outer upper arm
🌟 Rotate injection sites weekly to reduce skin irritation.
Can I self-inject Mounjaro at home?
Yes—but only after proper training and doctor’s approval.
You will need to learn:
- How to activate the auto-injector
- Proper cold storage (2–8°C)
- Safe disposal of used pens and needles
Initial doses are often administered at the clinic for safety.
What’s the starting dose?
| Week | Dosage | Note |
|---|---|---|
| Weeks 1–4 | 2.5 mg | Starter dose to reduce side effects |
| Week 5+ | 5.0 mg | Increased dose for weight loss effect |
Dosage can be adjusted (up to 15 mg) based on response and side effects—under doctor supervision.
How long before Mounjaro shows results?
Most patients notice:
- Reduced appetite
- 2–5 kg weight loss within 2–4 weeks
Significant, lasting results generally occur within 3–6 months.
Will my weight return after stopping Mounjaro?
Possibly—especially without long-term lifestyle changes.
Because Mounjaro reduces hunger, stopping the drug without a proper diet/exercise plan may result in:
- Regained weight within 2–3 months
- Yo-Yo effect
📌 Doctors typically recommend tapering off while introducing sustainable habits.
How is Mounjaro different from Ozempic and Wegovy?
| Feature | Mounjaro | Ozempic | Wegovy |
|---|---|---|---|
| Generic | Tirzepatide | Semaglutide | Semaglutide |
| Mechanism | Dual GLP-1 + GIP | GLP-1 only | GLP-1 (higher dose) |
| Weight loss | ⭐⭐⭐⭐ Best | ⭐⭐ Moderate | ⭐⭐⭐ High |
| Use case | Obesity + prediabetes/metabolic syndrome | Type 2 diabetes | Obesity (non-diabetic) |
| Thai FDA Approved | ✅ | ✅ |
📌 Mounjaro is the only dual-action drug (GLP-1 & GIP) and has shown the highest weight loss outcomes in studies.
How much weight can I lose in 1 month?
| Timeframe | Estimated Weight Loss |
|---|---|
| 1 month | 2–5 kg |
| 3 months | 7–10 kg |
| 6 months | 12–20 kg |
Results vary depending on dosage, diet, and exercise.
Which is best: Mounjaro, Ozempic, Saxenda, or Wegovy?
| Drug | Mechanism | Weight Loss Power | Frequency | Notes |
|---|---|---|---|---|
| Mounjaro | GLP-1 + GIP | ⭐⭐⭐⭐ | Weekly | Fast, high impact |
| Ozempic | GLP-1 | ⭐⭐ | Weekly | Good for diabetes |
| Wegovy | GLP-1 (high dose) | ⭐⭐⭐ | Weekly | For obesity |
| Saxenda | GLP-1 | ⭐ | Daily | Gentle, older option |
💬 For fast, noticeable weight loss → Mounjaro is most effective.
However, medical assessment is key to choosing the right option.
Does Mounjaro really reduce appetite?
✅ Yes—most users report:
- Feeling full faster
- Fewer hunger cravings
- Less desire for sweets and fatty foods
Mounjaro delays stomach emptying and signals “fullness” to the brain earlier, reducing calorie intake without strict dieting.
Is Mounjaro suitable for non-diabetics?
✅ Yes—especially for people with:
- BMI ≥ 27
- Fatty liver (NAFLD)
- Prediabetes or insulin resistance
- High cholesterol or triglycerides
In many countries like the USA, Mounjaro is approved for weight management alone, even in non-diabetics.
📌 In Thailand, physician evaluation is still required.ม
Summary
Mounjaro (Tirzepatide) is a breakthrough treatment for weight loss and Type 2 diabetes, working through dual hormone pathways (GLP-1 + GIP) for superior results. Backed by global research, it offers a powerful solution for individuals struggling to lose weight with previous medications.
