Retatrutide for sale in 24mg research vials

Retatrutide for sale here is supplied as a lyophilized peptide in 24mg vials, intended strictly for laboratory research. Packs hold 2, 5, 10 or 20 vials, giving 48mg, 120mg, 240mg or 480mg per order, so a pilot assay and a long study series can both run from the same lot. Every lot is sent for independent third-party testing before it is listed.

What is GLP-3 (retatrutide)?

Retatrutide, known in the literature by its development code LY3437943, is a single synthetic peptide with agonist activity at three receptors: GIP, GLP-1 and glucagon. Earlier incretin peptides act at one or two of these targets, so the triple-agonist profile is what has made retatrutide a reference compound in current metabolic research. Because all three activities are built into one molecule, a study does not have to balance separate agonists against each other, which simplifies experimental design. Labs often run it side by side with the dual GIP/GLP-1 agonist in our tirzepatide 40mg vials to separate the contribution of glucagon receptor activity from the incretin signal. The product name uses the shorthand GLP-3, which researchers also search as GLP3 or GLP-3 RT; the FAQ below explains what that label does and does not mean.

Retatrutide cost and pack sizes

  • 2 vials × 24mg = 48mg pack
  • 5 vials × 24mg = 120mg pack
  • 10 vials × 24mg = 240mg pack
  • 20 vials × 24mg = 480mg pack
The 24mg vial is the only retatrutide strength we stock, so every pack is built from identical units. The retatrutide cost per mg falls as the pack size rises, and the live price for each pack is shown above.

Buy tested retatrutide online in the USA

If you are comparing where to buy retatrutide, start with the paperwork.

GLP-3 Retatrutide FAQ

Is GLP-3 the same as retatrutide?

Yes. GLP-3 Retatrutide is this store’s product name for retatrutide (LY3437943). GLP-3 is a catalogue label, not a receptor class, and there is no GLP-3 hormone. Retatrutide is a single peptide with agonist activity at the GIP, GLP-1 and glucagon receptors, which is why it is called a triple agonist.

How much is retatrutide?

Pack prices are printed live near the top of this page for the 48mg, 120mg, 240mg and 480mg packs. Every pack uses the same 24mg vial, so the price per mg drops as the pack grows, and the 20-vial pack carries the lowest cost per mg.

Where can I buy retatrutide in the USA?

Peptide Partners sells retatrutide for laboratory research through this US storefront. Orders are paid with CashApp, Apple Pay, Chime or cryptocurrency, free-shipping eligibility is worked out in the cart, and an order can be cancelled for a full refund at any time before it ships.

How is each retatrutide lot tested?

Every lot goes to an independent third-party laboratory before it is listed, and the current lot passed endotoxin and purity screening. Its results appear in the specification table and the Certificates tab, and the full certificate record can be looked up by batch ID in the independent certifications ledger.

What form does retatrutide 24mg arrive in?

It arrives as a lyophilized, freeze-dried powder sealed in 24mg vials. Unopened vials belong in a freezer for long-term storage, kept dry and away from light. Researchers reconstitute the powder with bacteriostatic water in the lab, and the Storage tab covers handling after that step.

How to store retatrutide 24mg vials

Retatrutide ships as a freeze-dried powder, and that powder is at its most stable while the vial stays sealed. For long-term storage, keep unopened 24mg vials in a freezer; for short spells, a cool, dry, dark cabinet works. Leave vials in their carton until needed, since light and humidity both work against a lyophilized peptide, and avoid letting a sealed vial warm and re-chill repeatedly.

Once a vial is reconstituted, store it refrigerated and draw from it only with sterile technique. Labs typically reconstitute retatrutide with bacteriostatic water for reconstitution, sold as a separate listing.

At a glance

  • Sealed vials: freezer for long-term storage
  • Short term: cool, dry and dark
  • After reconstitution: refrigerated, sterile handling
  • Avoid repeated warming and light exposure

Retatrutide in the GLP research line

Of the four compounds in our GLP research line, retatrutide has the broadest receptor profile. Semaglutide acts at the GLP-1 receptor alone, tirzepatide adds GIP, and retatrutide extends the set to the glucagon receptor, which makes it the natural top end of a receptor-comparison study. Cagrilintide, an amylin analogue, sits outside the incretin family altogether.

Studies that build a stepwise comparison usually pair this 24mg vial with the single-receptor reference in our semaglutide 10mg vials, so each added receptor can be examined against a known baseline. Both are held to the same lot-testing and certificate standard.
