GLP-1 Peptide Kits Compared: Retatrutide, Tirzepatide and Semaglutide

Three kits, one format

Retatrutide, Tirzepatide and Semaglutide are sold in this catalog in the same format: a sealed box of five lyophilized vials with a separate 11ml vial of bacteriostatic diluent, marked to be refrigerated. What changes from one to the next is the compound and the strength of each vial, and with it the total printed on the kit.

That shared format makes the three easy to line up, and it also hides the one detail that is easiest to get wrong: the number in each product name is the kit total, not the strength of a single vial.

The baht figure is approximate at the current exchange rate and checkout is charged at the dollar price. The totals are not comparable between compounds: each kit is built around its own vial strength.

What GLP-1 means in the name

GLP-1 stands for glucagon-like peptide-1, the name of a hormone family. Compounds in this group are classified by the receptors they act on, and that classification is all the name tells you. Semaglutide is described as a GLP-1 receptor agonist. Tirzepatide is described as a dual GIP and GLP-1 receptor agonist, where GIP stands for glucose-dependent insulinotropic polypeptide. Retatrutide is described as a triple agonist of the GIP, GLP-1 and glucagon receptors.

These are classification terms from the way the compounds are described, and they are the vocabulary the product pages use. They are not a comparison of effects, and nothing on this page says how any of them is used.

Kit total or vial strength: the number in the name

Retatrutide 10mg holds 2mg in each vial, so the kit total is 10mg. Tirzepatide 25mg holds 5mg in each vial, so the kit total is 25mg. Semaglutide 5mg holds 1mg in each vial, so the kit total is 5mg.

When a price seen elsewhere uses one of these numbers, check whether it counts one vial or a whole kit, and whether a diluent vial is packed with it. A lower headline number can simply describe less in the box, and a single vial priced next to a five-vial kit is not the same offer.

Why prices do not compare per milligram

It is tempting to divide each price by its milligrams and pick the lowest figure. For these three kits that comparison is meaningless, because the vial strengths differ and a milligram of one compound is not a milligram of another. A kit with a bigger total is not a bigger amount of the same thing.

At current prices the lowest-priced of the three kits is Semaglutide 5mg at approx. ฿1,200 / $35.00, and that is a fact about price only. To compare two prices fairly, compare the same compound in the same kit, and use the live price on each listing.

Cold chain from the courier to the fridge

All three boxes are marked to be refrigerated, so the plan for the fridge comes before the order. The sealed vials handle normal courier transit; the exposure that matters in Thailand is the time between drop-off and the fridge, in a condo mail room, on a reception desk or in a parked vehicle.

Pay early in the day if you want a same-day delivery in Bangkok or Pattaya, because dispatch waits for payment confirmation, and give an address where someone can receive the parcel and put it straight into the refrigerator. Keep the diluent vial together with the peptide vials and the box out of light. The storage guide covers every format.

Reading the box and the vial

A kit box carries a few panels that are the quickest check that the parcel matches the listing: the kit total in one corner next to the refrigerate marking, the strength per vial on another panel, and a printed compound identifier. A security strip runs across the lid. Each vial carries its own batch number and expiry date. Compare the printed kit total and the per-vial strength with the listing, check that the seal and strip are intact, and photograph the box before opening anything if a panel disagrees with the page.

Which GLP-1 kit is the cheapest in Thailand?

At current prices Semaglutide 5mg is the lowest-priced of the three, at approx. ฿1,200 / $35.00. The kits hold different strengths per vial, so the lowest price is not the same amount of anything: read the totals in the table first.

How many vials are in each kit?

Five lyophilized vials in each, plus one sealed 11ml vial of bacteriostatic diluent. What differs is the strength of each vial: 2mg for Retatrutide, 5mg for Tirzepatide and 1mg for Semaglutide.

Do the GLP-1 kits include bacteriostatic water?

Yes. Each kit includes one sealed 11ml vial of bacteriostatic diluent packed with the five peptide vials.

Do the kits need refrigeration in Thailand?

The boxes are marked to be refrigerated. Receive the parcel in person where you can, and move the unopened kit into the fridge in its box, away from light.

What is the difference between retatrutide and tirzepatide?

On the labels, the compound and the vial strength: Retatrutide is described as a triple GIP, GLP-1 and glucagon receptor agonist at 2mg per vial, and Tirzepatide as a dual GIP and GLP-1 receptor agonist at 5mg per vial. This page compares labels, not effects.

Can a GLP-1 kit be delivered to Phuket or Chiang Mai?

Yes, by express domestic courier. Choose an address where the kit can go into a refrigerator as soon as it arrives.
