Mounjaro is officially available in Thailand through licensed doctors, hospitals, and clinics. The currently available doses include Mounjaro 2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, and 15 mg pens, each designed as a multi-dose injector suitable for four weekly doses. Patients seeking to buy Mounjaro pens in Bangkok must consult a licensed medical professional to obtain a valid prescription and ensure proper medical supervision.

Obesity and diabetes have reached epidemic levels globally, posing serious health risks. In 2022, 1 in 8 people worldwide were living with obesity, and rates have more than doubled since 1990. Thailand is no exception, with rising cases of Type 2 diabetes and metabolic disorders. These conditions significantly increase the risk of heart disease, stroke, and certain cancers, indicating an urgent need for effective medical interventions.
Many individuals struggle with long-term weight management despite diet and exercise. Hormonal imbalances, insulin resistance, and metabolic dysfunction make it difficult for the body to regulate fat storage and energy use, leading to weight regain.
Mounjaro (Tirzepatide) targets both GIP and GLP-1 receptors, improving insulin sensitivity, appetite control, and fat metabolism. This dual-action therapy provides sustainable weight loss and blood sugar control, offering hope for patients who have struggled with traditional approaches.

Mounjaro (Tirzepatide) is revolutionizing weight loss treatment with its unique dual GIP and GLP-1 receptor activation, providing more effective fat reduction and appetite control than traditional medications. By enhancing metabolism and reducing cravings, Mounjaro helps patients achieve significant, sustainable weight loss.
According to the clinical studies on weight loss, the SURMOUNT-1 clinical trial, published in The New England Journal of Medicine (NEJM), found that patients taking 15mg of Mounjaro lost up to 22.5% of their body weight over 72 weeks. These results make Mounjaro one of the most effective weight loss medications, surpassing GLP-1-only treatments like Ozempic, Saxenda, and Wegovy.

Mounjaro (Tirzepatide) is a first-in-class medication that activates both GIP and GLP-1 receptors, making it more effective than traditional GLP-1-only treatments. This section explores how Mounjaro compares to Zepbound (another Tirzepatide-based medication) and GLP-1 medications, like Ozempic and Wegovy, in Bangkok.
Although both contain Tirzepatide, they are marketed under different names depending on the country. In some regions, Zepbound is branded for weight loss, while Mounjaro is designated for diabetes treatment.
In Thailand, however, Mounjaro is officially approved for both Type 2 diabetes and weight loss, making it a versatile treatment option for patients managing obesity or diabetic conditions.
Mounjaro’s dual-incretin mechanism gives it an advantage over Semaglutide-based medications, providing stronger metabolic and fat-loss benefits. Mounjaro activates both:
  • GIP (Glucose-dependent insulinotropic polypeptide) – Enhances insulin release and improves fat metabolism.
  • GLP-1 (Glucagon-like peptide-1) – Regulates appetite, slows digestion, and lowers blood sugar.
  • Mounjaro (Tirzepatide 15mg) – Up to 22.5% weight loss and 2.3% HbA1c reduction.
  • Wegovy (Semaglutide 2.4mg) – Up to 16% weight loss and 1.86% HbA1c reduction.
  • Ozempic (Semaglutide 1mg) – Moderate weight loss and diabetes management.
At H.U.M. Clinic, Mounjaro (tirzepatide) is priced by dose, starting at 13,900 THB for the 2.5 mg dose and increasing with higher doses up to 15 mg. A doctor consultation is 1,500 THB per visit. For the full dose-by-dose Mounjaro price list, see our Mounjaro pen price and packages in Bangkok.

This patient came to us at 94.4 kg and, over six months on Mounjaro at 2.5 mg then 5 mg, reached 77.0 kg, a loss of 17.4 kg (18.4%). Almost all of that loss came from fat: his body fat mass fell from 23.1 kg to 5.3 kg, and his percent body fat dropped from 24.5% to 6.9%. What we look for most is that muscle is kept, and his skeletal muscle actually held and rose slightly from 41.1 kg to 41.4 kg. His visceral fat, the fat stored around the internal organs, came down from a level of 10 to 1, which matters a great deal for long-term heart and metabolic health.

Clinic Bangkok: over six months, weight fell from 94.4 kg to 77.0 kg and body fat mass from 23.1 kg to 5.3 kg, while skeletal muscle was preserved (41.1 kg to 41.4 kg) and visceral fat dropped from level 10 to 1.
In only seven weeks on Mounjaro at 2.5 mg then 5 mg, this patient reduced his body fat mass from 27.2 kg to 18.2 kg, a drop of about 33%. His weight moved from 103.1 kg to 94.9 kg over the same period, a 7.9% reduction. Just as important, his muscle stayed intact, holding from 43.2 kg to 43.3 kg, so the early change was fat coming off rather than muscle. His visceral fat level also improved quickly, from 12 to 8 (a 33.3% reduction), which is an encouraging sign this early in treatment.

Over nine months, with his dose adjusted in steps from 2.5 mg up to 10 mg, this patient lowered his body fat mass from 18.9 kg to 10.5 kg, a loss of 8.4 kg (44.4%), and his percent body fat fell from 19.7% to 12.4%. His weight came down from 95.8 kg to 84.3 kg, a 12.0% reduction. His skeletal muscle changed only slightly, from 44.2 kg to 42.1 kg, a small shift compared with the amount of fat he lost. His visceral fat improved from a level of 7 to 4, a 42.9% reduction.

Over four months, with her dose stepped from 2.5 mg up to 7.5 mg, this patient reduced her body fat mass from 26.1 kg to 18.5 kg, a loss of 7.6 kg (29.1%), and her percent body fat moved from 39.7% to 33.0%. Her weight came down from 65.8 kg to 55.9 kg, a 15.0% reduction. Her skeletal muscle shifted modestly from 21.8 kg to 20.2 kg. Her visceral fat level dropped from 13 to 8, a 38.5% reduction.

How does Mounjaro work for weight loss patients?

Mounjaro (tirzepatide) works for weight loss by mimicking two natural gut hormones, GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide), which together suppress appetite, increase feelings of fullness, and slow gastric emptying. As a dual-agonist medication, it acts on brain receptors to reduce hunger to support a sustainable calorie deficit.
