Retatrutide in Chiang Mai: Delivery, Prices and Storage
Retatrutide in Chiang Mai sits in an odd gap. The city has the largest digital nomad and long stay community in the north, a serious hospital sector, and a research minded crowd around the university, and yet research peptide supply has meant ordering from Bangkok sellers of uncertain quality or from overseas with a long wait. Reta Bangkok now delivers tested stock to Chiang Mai in one to two days, from Nimman to Hang Dong, which closes that gap. This page covers delivery, pricing, the cool season storage question that Chiang Mai raises, and what to check before ordering.
Reta Bangkok supplies retatrutide strictly for laboratory research. Nothing on this page is medical advice.
The short version
- Retatrutide is not an approved medicine, so no Chiang Mai pharmacy or hospital can supply it. It is available only as a research compound.
- Reta Bangkok delivers to Chiang Mai city and the surrounding districts by tracked courier in one to two days.
- Prices are the same as Bangkok: ฿2,800 for 10 mg to ฿9,600 for 60 mg, with bulk, order and payment discounts.
- Every batch is independently tested, certificate on the product page, QR code on the vial.
- Chiang Mai’s cool season does not change the storage rule: fridge on arrival, fridge after reconstitution.
Why Chiang Mai has no local supply
Chiang Mai’s hospitals are among the best in the country, and the private ones can supply the approved GLP-1 medicines, semaglutide and tirzepatide, with a consultation. Retatrutide is a different case: still in Phase 3, approved nowhere, so there is no registered product to prescribe or stock. The pharmacies around Nimmanhaemin and the Old City have the same limit. Anything sold as retatrutide in Chiang Mai is a research compound, and the question is only whether it has been tested.
The local informal market is thinner than Bangkok’s or Phuket’s. There are fewer gym sellers and fewer Line contacts, which sounds safer but means the few that exist have no competition and no reason to test anything. Our buying guide lists the six things to check on any vial. The most important in Chiang Mai is the certificate of analysis, because the supply here is almost all second hand from Bangkok and the certificate is the only link back to a tested batch.
How delivery to Chiang Mai works
Stock sits in Bangkok. Orders placed before 3 pm go out the same afternoon by tracked courier. Chiang Mai city, Nimman, the Old City, Santitham, Chang Phueak and the Night Bazaar area are usually next day. Hang Dong, San Sai, Mae Rim, Doi Saket and San Kamphaeng are next day or the day after. Further north, Chiang Rai and Pai are two to three days. You get a tracking number when it ships, and the courier delivers to a condo reception, a guesthouse front desk or a house gate.
Chiang Mai addresses are easier than Phuket’s but the moo baan estates outside the ring road still trip couriers up. Give the estate name, the house number and the nearest main road, plus a phone number. Condos in Nimman and the Old City are straightforward; use the building name and let reception know.
The cool season question
People in Chiang Mai sometimes ask whether the cool season, when nights drop to 10 or 12 °C from December to February, means the vial can sit out of the fridge. It does not. The sealed lyophilised vial is stable at room temperature for weeks, in any Thai season, so the delivery itself is never the issue. But “cool” in Chiang Mai still means 30 °C by afternoon, and a reconstituted vial needs 2 to 8 °C continuously, not a cool night and a warm day. Refrigerate the sealed vial on arrival, and refrigerate the solution after reconstitution, in every month of the year. The reconstitution guide covers the full process.
The burning season, March and April, is the other local factor, and it changes nothing for the vial either. Keep the parcel indoors once it arrives and the smoke is irrelevant to a sealed glass vial.
What retatrutide costs delivered to Chiang Mai
The same as Bangkok. There is no regional markup for the north.
| Vial | Price | Per mg |
|---|---|---|
| Retatrutide 10 mg | ฿2,800 | ฿280 |
| Retatrutide 20 mg | ฿4,600 | ฿230 |
| Retatrutide 30 mg | ฿5,900 | ฿197 |
| Retatrutide 40 mg | ฿6,900 | ฿173 |
| Retatrutide 60 mg | ฿9,600 | ฿160 |
Three vials of the same product take 10 percent off automatically, five take 12 percent, ten take 15 percent, with order level discounts above ฿15,000. Wise and crypto take a further 5 and 10 percent at checkout. With the extra day of delivery, ordering for a longer period at once makes sense; the price guide has a worked example of what the discounts do to the per milligram cost.
Paying from Chiang Mai
Visa, Mastercard, Wise and cryptocurrency, in baht. The nomad community in Chiang Mai lives on Wise and crypto already, and both carry a discount with us because they cost less to process. There is no cash on delivery.
Order bacteriostatic water with it
Chiang Mai pharmacies stock sterile water, which has no preservative and is the wrong product for a multi use vial. Add a 3 ml vial of bacteriostatic water at checkout. Our bacteriostatic water page explains the difference, and the calculator handles the concentration.
