How much does Mounjaro cost in Bangkok?
Bangkok clinic prices for brand Mounjaro run 6,500 to 16,500 THB per month (about $180 to $450 USD) for a 5 to 10 mg weekly protocol, consultation included. Direct research-chem vendors run 3,000 to 8,000 THB. Confirmed April 2026.
What you actually pay, by channel
Bangkok has three real channels: clinic with imported Mounjaro brand (6,500 to 16,500 THB/month), a handful of direct vendors selling research-grade tirzepatide (3,000 to 8,000 THB/month), and telehealth routes for expats (similar to clinic pricing). Chiang Mai and Phuket tend to be 20 to 40 percent more expensive than Bangkok for equivalent service.
Why the range is wide
Your monthly cost depends on dose progression. Week 1 through 4 at 2.5 mg is cheap because you use a fraction of a vial. Week 5 onward at 5 mg is full-monthly. By week 13 on 10 mg you are at the upper range. Clinics that quote a single number are usually quoting the first month, not your average.
Watch for
Prices under 5,000 THB per month in Bangkok for brand Mounjaro are suspicious. Lilly's wholesale cost alone makes this implausible. Either the pen is counterfeit or the clinic is selling expired product. See our guide on spotting fake pens if you have any doubt about what you have.
