I went to four Bangkok clinics and asked the same five questions

I spent a Tuesday afternoon in Sukhumvit doing something I should have done months ago. I walked into four clinics that all advertise tirzepatide, asked the same five questions at each one, and took notes.

The clinics: a premium clinic in Ekkamai, a mid-tier clinic on Sukhumvit Soi 23, a hospital outpatient department in central Bangkok, and a smaller aesthetic clinic in Thonglor. I'm not naming them because I'm writing this up against the experience, not the operators. The point isn't to rank these four. The point is to show how much variance there is and how you might actually choose.

The five questions:

1. What does a 5mg dose cost per month, all-in? 2. Where does your tirzepatide come from? 3. Who is the prescribing doctor and what's their background? 4. What happens if I have a bad reaction? 5. Can I get my labs done here, or do I need to go elsewhere?

Here's what happened.

The premium clinic in Ekkamai. Price: 14,500 baht per month including a brief consultation. The consultation was unhurried. The doctor (a Thai-trained internist with what looked like a real practice) walked me through the side effect profile, asked about my health history, and offered to do baseline labs in their building. Tirzepatide came from the official Lilly Thailand distribution chain; she showed me the box. Reaction protocol was specific: a number to call, a doctor on call evenings and weekends, an instruction to come in immediately if certain things happened. Labs done in-house. The price was the highest. The product and the safety net were the cleanest.

The mid-tier clinic on Soi 23. Price: 8,500 baht. The receptionist quoted me without me asking the doctor first, which was a yellow flag. The doctor was rushed (the room turned over fast). He confirmed the source as the official channel but didn't show me the box. Reaction protocol: "call us, we open at 9am." Labs were a separate appointment at a partner facility, additional cost. The product was probably the same as the premium clinic. The everything-around-the-product was thinner.

The hospital outpatient department. Price: 11,200 baht for the medication, plus a 1,500 baht consultation fee, plus they wanted recent labs from somewhere. The structure of the appointment was the most clinical. The doctor was a board-certified endocrinologist. The downside: the wait was an hour despite my appointment, and the prescription required a follow-up visit in four weeks (also paid). It was the most thorough conversation I had all day. It was also the most expensive total experience because of the additional fees.

The smaller aesthetic clinic in Thonglor. Price: 6,000 baht. Quoted with no consultation, no questions about my health history, no source verification (I asked; the answer was vague). The doctor wasn't on site at the time and they offered to write the prescription via a remote consultation. I left without buying. This is what the bottom of the market looks like.

The five-question test cut through the marketing language faster than anything I'd tried before. Each question is open-ended enough to surface a real gap if there is one. "Where does your tirzepatide come from" sounds polite. The answer reveals a lot. A clinic that says "official Lilly distribution, here's the box" is in a different category than one that mumbles or pivots to talking about price.

What I'd actually use for choosing, given the four:

If price is the binding constraint and you're an experienced patient who knows the medication well, the mid-tier on Soi 23 is fine. The product is real. The handholding is thin. You're paying less and getting less around the prescription, but the medication itself is the same.

If you're starting tirzepatide for the first time, or you have any health complications, the premium clinic in Ekkamai or the hospital is what you want. The cost difference is meaningful (5,000-7,000 baht per month) but the difference in what happens when something goes wrong is bigger than the price gap.

The aesthetic clinic in Thonglor is where I'd send a vendor I was trying to get filtered out of the catalog. Not because I think the product is bad. Because the surrounding apparatus tells me they aren't set up to handle the things that go wrong.

The thing I keep thinking about a week later is how invisible most of this is from the outside. From their websites, all four of these clinics look pretty similar. Modern photos. The same stock language about evidence-based weight management. Similar testimonial blocks. The differences are entirely in the consultation room. A patient who has only ever bought from the website is making the decision blind.

The five-question test takes about fifteen minutes per clinic. If you're choosing where to start a medication you might be on for a year or more, fifteen minutes per option is a deal.
