Retatrutide price in Thailand runs from about ฿1,500 to ฿4,500 for a 10 mg vial, depending on who you buy from, and that spread is the whole story. At the bottom are chat sellers with no testing. At the top are overseas vendors once shipping and card fees are added. In the middle sit the Thai suppliers that hold tested stock locally. This page breaks the price down: what a vial costs by size, what you are paying for at each level, why the per milligram price drops so steeply with larger vials, and how the discounts stack.

Reta Bangkok supplies retatrutide strictly for laboratory research. Nothing on this page is medical advice. Prices are correct at the time of writing and shown in Thai baht.

Retatrutide price by vial size

Our list prices. Other Thai suppliers that test their batches sit within a few hundred baht of these.

Vial	Price	Per mg	Saving vs 10 mg vials
Retatrutide 10 mg	฿2,800	฿280	0%
Retatrutide 20 mg	฿4,600	฿230	18%
Retatrutide 30 mg	฿5,900	฿197	30%
Retatrutide 40 mg	฿6,900	฿173	38%
Retatrutide 60 mg	฿9,600	฿160	43%

The pattern is steep. Six 10 mg vials cost ฿16,800; one 60 mg vial with the same amount of peptide costs ฿9,600. The reason is that most of the cost of a vial is not the peptide. It is the vial, the stopper, the cap, the label, the lyophilisation run, the lab test and the handling, and those cost the same whether there is 10 mg or 60 mg inside. A larger vial spreads the fixed cost over more milligrams.

What the three price levels actually buy

฿1,200 to ฿1,800: chat sellers

Telegram, Line and Facebook sellers buy bulk powder, fill their own vials or resell unlabelled ones, and sell by message. The price is low because nothing has been spent on testing, labelling or traceability. Sometimes the product is real and correctly dosed. Often it is underdosed, and occasionally it is a different compound altogether. Since there is no certificate and no batch number, the buyer finds out by results, or does not find out at all. The saving over a tested vial is about ฿1,000. The risk is the entire vial.

฿2,500 to ฿3,200: Thai suppliers with tested stock

This is the price of a vial that has been through an independent lab, carries a printed batch number, matches a published certificate, and can be delivered in Bangkok the same afternoon. The extra ฿1,000 over the chat seller pays for the test, the label, the sealed packaging and a supplier you can go back to. Reta Bangkok sits in this band.

฿3,500 to ฿4,500: overseas vendors, delivered

The American and European research vendors list a 10 mg vial at a price similar to the Thai suppliers. Then international shipping, a foreign card transaction fee and currency conversion add 30 to 50 percent, and the parcel takes two to three weeks to arrive, if customs lets it through. The product is good. The price, once it is in your hand in Thailand, is the highest of the three.

How the discounts stack

List price is the starting point, not the number most orders pay. Three discounts apply at Reta Bangkok, and the cart works them out automatically.

• Bulk vial discount. Three vials of the same product, 10 percent off. Five, 12 percent. Ten, 15 percent.
• Order discount. Orders over ฿15,000 take 5 percent, over ฿30,000 take 8 percent, over ฿50,000 take 10 percent. You get whichever of the bulk or order discount is larger, not both.
• Payment discount. Wise takes a further 5 percent off and crypto takes 10 percent, applied on top of the above at checkout.

Worked example: three 60 mg vials list at ฿28,800. The bulk discount takes 10 percent, bringing it to ฿25,920. Paying by crypto takes a further 10 percent, to ฿23,328. That is 180 mg of tested retatrutide at ฿130 per milligram, less than half the per milligram price of a single 10 mg vial.

Why there is no pharmacy price

Retatrutide is in Phase 3 trials and has no approval anywhere, so there is no branded product and no pharmacy price in Thailand or elsewhere. The only comparison available is to the approved compounds in the same class. Branded tirzepatide and semaglutide through Thai private hospitals cost well above the research vial per milligram, because the price includes the brand, the pen device, the consultation and the hospital’s margin. Our tirzepatide in Thailand page covers that comparison for the dual agonist.

Will the price fall?

Research peptide prices tend to fall as manufacturing scales, and retatrutide has followed that pattern. Two things could move it further. Phase 3 results in 2026 and 2027 will raise demand, which tends to push prices up in the short term. Wider manufacturing capacity pushes them down. Our expectation is that per milligram prices drift lower over the next year while the larger vial sizes stay the better value, as they are now.
