The cost of weight-loss injections in Bangkok depends on the medicine, the brand, the dose you reach and how long you stay on treatment, plus consultation and monitoring. Because dosing rises gradually and is individual, we confirm pricing at consultation rather than quoting a single figure.
Cost is one of the first questions people ask, and it is a reasonable one. But it is also the question I am most cautious about answering with a single number, because a headline figure often misleads more than it helps. What you actually pay depends on several moving parts, and I would rather explain those honestly than quote a price that turns out to be wrong for you.
In this guide I break down what drives the cost of weight-loss injections in Bangkok, so you can plan realistically and understand your consultation quote when you get it.
What actually drives the cost
The medicine and brand
Semaglutide and tirzepatide products are priced differently, and brand availability affects what you pay. See our guides to Ozempic in Thailand and Mounjaro in Thailand.
The dose you reach
Because these medicines are titrated up over time, your monthly cost early on can differ from later, once you settle at a maintenance dose. Higher doses generally cost more.
Duration of treatment
These are not one-off treatments. Because appetite tends to return after stopping, the sensible way to think about cost is monthly over a planned period, not as a single purchase.
Beyond the medicine: consultation and monitoring
A safe programme includes more than the drug itself. There is the initial screening consultation, often baseline blood tests, and follow-up reviews to manage dose and side effects. These are not padding; they are what makes treatment safe and are part of the true cost of doing this properly. A general health check-up can form part of that baseline.
Why we confirm pricing at consultation
Because your dose, chosen medicine and duration are individual, a single advertised price would be misleading. We confirm your pricing at consultation once we understand your situation. This is also more honest than a low headline figure that quietly excludes the monitoring you actually need.
The false economy of buying cheap online
Unverified online sources may look cheaper, but the savings are risky. You lose the screening that keeps you safe, the supervision that manages side effects, and you face a real risk of counterfeit product. A slightly lower sticker price is poor value if the medicine is unsafe for you or fake. Eligibility screening, covered in our eligibility guide, is part of what you pay for.
When to see a doctor
Before spending anything, see a doctor to confirm these injections are right for you; that assessment protects both your health and your money. And if you are on treatment and develop severe abdominal pain, persistent vomiting or an allergic reaction, seek prompt care. Our 24/7 clinic in central Bangkok is available whenever you need it.

Frequently asked questions
Why won’t you just tell me a price?
Because your dose, medicine and treatment length are individual, a single number would likely be wrong for you. We confirm accurate pricing at consultation.
Is Mounjaro more expensive than Ozempic?
It depends on dose, brand and duration. Neither is reliably cheaper in every case; we confirm the cost for your specific plan.
Does the cost change over time?
It can. Because the dose is titrated up, your early monthly cost may differ from your maintenance-dose cost later.
Are consultations and blood tests extra?
Screening, any bloods and follow-up reviews are part of a proper programme. We explain what is included when we confirm your pricing.
Isn’t buying online cheaper?
It may look cheaper but carries real risks: no screening, no supervision, and possible counterfeit product. That is usually a false economy.
