Where to buy Retatrutide (also sold as GLP-3 R, GLP-3 RT): the 28 vendors below are the ones we have a dated product-page price for, ranked on documentation first and price second. Nothing here is typed from memory — every number links to a date.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.
Per-milligram price is list price over labelled milligrams; it says nothing about what is in the vial. Code prices are list × (1 − the code's stated discount), not cart-tested against sales. We earn a commission on partner links; the rubric does not read partner status.
Reference size 10mg — the size most of these vendors sell. Other sizes we have on record are listed per vendor.

Retatrutide is the hardest of the GLP-class compounds to source responsibly, and the reason is straightforward: it is not approved anywhere. Status as of 9 October 2026: all four Phase 3 TRIUMPH trials have reported positive results, no FDA application has been filed, and Lilly has said it plans to file in the first quarter of 2027, which puts any decision in late 2027 or 2028. There is no FDA-approved reference product, so there is no pharmacy-grade benchmark to compare a vial against. Everything rests on the vendor's documentation.
Vendors rarely list it by name. It is sold as GLP-3 R, GLP-3 RT, RETA and other house codes. The decoder table below shows what each vendor calls it and how we established the identity — a CAS number on the listing, the lab lot prefix on the vendor's own certificate page, or the vendor's FAQ. A code with none of those is a code only, and we keep it out of the price table.
That also thins the field. Many vendors that stock semaglutide and tirzepatide do not carry retatrutide at all, and several that do added it recently without a track record behind it. Combined with Eli Lilly's litigation against GLP-1 suppliers and the wave of vendor closures through 2025–26, the practical question is less 'who is cheapest' than 'who will still be here, and can prove what is in the vial'.
The ranking below weights exactly that: an independently viewable review history, a named testing laboratory where one exists, and batch-specific COAs you can match to your vial.
Almost no vendor lists Retatrutide by name any more. The table shows the code each one sells it under and how we established that the code means Retatrutide — a CAS number on the listing, the lab lot prefix on the vendor's own certificate page, or the vendor's own FAQ. A code with no stated identity is listed as exactly that: the vendor is asking to be taken on trust, and we do not put those in the price table above.

What we can verify
Publishes per-lot COAs naming the testing laboratory — SteriGenix and Freedom Diagnostics — with lot numbers, test dates, measured net peptide content and direct verify-at-lab links. HPLC and mass spectrometry testing, US-based fulfilment from Scottsdale, Arizona, same-day dispatch on weekday orders before 2PM EST, and a 60-day money-back guarantee.
Net content: Measured net peptide published per lot (e.g. BPC-157 lot PL-BPC-05: 11.16mg vs 10mg label)
Where it falls short
Smaller independent review base than several competitors (101 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.

Where it falls short
The printed address (12407 N Mopac Expy Ste 250 PMB 570, Austin) is a commercial mailbox, not premises — identity is awarded on the named LLC with that disclosure. The BPC-157 report measures 11.61mg on a 10mg label, 116% — just over our 115% flag line; TB-500 10mg measured 11.54mg. The vendor's own site says a report 'alone does not confirm the lot shipped'. The GLP-class pages print strike-through reference prices far above the selling price (Semaglutide 10mg 'was $399.99', now $70; Retatrutide 10mg 'was $699.99', now $80) — treat the 'you save' figures as marketing. Zelle is offered alongside cards. Returns: 7-day unopened window with a continuous unboxing video required for damage claims. A domain lookalike (mypurepeptides.com) is disclaimed on the vendor's homepage.

Where it falls short
Prices and certificates need a free account (no purchase), which since 1 November 2026 no longer costs the ungated point. All sales are final, with damage to be reported within 24 hours; checkout takes cards, but Zelle carries a 5% discount and the FAQ still lists only Zelle, Cash App, Venmo and ACH. The product pages say 'up to 12X' (ILS lots) and the cart says 'up to 16X'; both hold, because Oneday's Ethos Analytics reports carry a wider panel (checked on CJC-1295/Ipamorelin lot OC-CJI10-104, 1 November 2026). GLP-class products are sold by code (OC-2TZ, OC-3RT); the lab confirms retatrutide for OC-3RT.
Purgo Labs sits at #1 of 28 on this page: 10/10 on the rubric, 10mg at $59.99 read 1 Nov 2026 (also 15mg $84.99, 20mg $119.99, 30mg $159.99, 60mg $219.99). Code HEALTH gives 20% off every order. We earn a commission; it did not decide the order above.
Before you order, check the batch
A ranking tells you which vendors have good practices; it cannot tell you about the specific vial you receive. When your order arrives, compare the batch number on the label to the certificate. If they do not match, or there is no batch number, the documentation does not cover what you were sent, regardless of who you bought from. How to read a peptide COA.
As of 1 Nov 2026, 28 of the 105 vendors on our scoreboard list Retatrutide with a price we have read on the product page: Purgo Labs, MyPurePeptide, Oneday Compounds, Peptide Giants, Idun Peptides, Premier Bio Labs, Panda Peptides, Rivn Peptides, Amino Club, ezPeps, Oath Research, PS Peptides, Validated Peptides, Crush Research, Prime Peptides, Peptide Partners, Kylo Peptides, Value Research Labs, Disguised Alpha, Prime Lab Peptides, Evo Labs Research, Profound Aminos, Elite Edge Biotech, Blue Sky Peptide, Optima Supply, Peak Lab Peptides, Valor Peptides, Polaris Peptides. Every one of them is scored on the same 10-point rubric; the table above shows the score, the dated price and what you can verify before ordering.
At the 10mg size, the lowest price we have on record is Idun Peptides at $44.99 (read 5 Sep 2026) — sold as GLP-3 RT. It scores 10/10 on documentation. Price is the second sort key on this page, not the first, because an underdosed vial at a low price is the most expensive outcome.
Purgo Labs, MyPurePeptide, Oneday Compounds, Peptide Giants, Idun Peptides, Premier Bio Labs, Panda Peptides share the top score at 10/10: named laboratory, certificates that resolve on the laboratory's own site, measured milligrams against the label, and a published legal identity. The per-criterion evidence, with dates, is on each vendor's review page.
Retatrutide is sold by these vendors as a research chemical for laboratory use, not for human consumption; none of it is FDA-approved in this form. Legality of purchase varies by jurisdiction and the compound, and it is your responsibility to know your local rules. Our pages assess documentation and pricing; they are not legal or medical advice.
Rubric score first. Among equal scores, our editorial pick (Purgo Labs) comes first, then a short, named list of affiliate partners we choose to list first inside a tie, then the lower verified price per milligram at 10mg, then the larger independent review base. 13 of the 28 vendors here are partners. A partnership never changes a score and never moves a vendor above one with a higher score.
Retatrutide is sold as a research chemical for in-vitro laboratory use only. It is not approved by the FDA for human use anywhere — it remains in Phase 3 trials. Vendors selling it are supplying a research compound, not a medicine, and it is not legal to sell it for human consumption. Everything on this page concerns research sourcing standards only.
Two reasons. It is newer and still unapproved, so there is no established supply chain around it, and Eli Lilly — which developed retatrutide — has pursued litigation against GLP-1 suppliers, which has made some vendors cautious about the whole class. Several vendors that stock semaglutide and tirzepatide do not list retatrutide at all.
For an unapproved compound with no reference product, price should be the last filter rather than the first. A vial that is underdosed or misidentified is worthless at any price, and there is no pharmacy-grade standard to check it against. Prioritise vendors that publish batch-matched certificates and name their testing laboratory, then compare price among those that qualify.
