Retatrutide Peptide For Sale

How much does Retatrutide cost per month?

The cheapest verified Retatrutide protocol works out to about $21.82 per month: Modified Aminos's 100 mg vial at $251.99 with code WPA, dosed at 2 mg once weekly (the most-common community protocol). One vial provides 50.0 doses — about 50.0 weeks of supply at this cadence — so the per-week cost is roughly $5.04, which works out to $21.82 on a 4.33-week month. This protocol is derived from 60,122 verified Retatrutide calculator runs logged by the WPA community. Cost scales roughly linearly with the per-shot dose and weekly frequency you choose.

Use the live cost-per-month card directly above the vendor table to switch between vial size, per-shot dose, weekly frequency, and vendor strategy (cheapest cost per month across all vendors and vial sizes, or highest-quality vendor by verified COA purity). Every figure recalculates against the same verified pricing shown in the vendor table below.

What Retatrutide Costs Right Now

WPA currently tracks Retatrutide at 14 verified vendors across 45 separate Retatrutide listings. In-stock Retatrutide vials run from $36.25 to $944.99 — a 26.1x spread for the same compound. Ascension Peptides holds the lowest sticker price at $36.25. Normalized to milligrams, Retatrutide costs $2.52/mg to $13.50/mg on this page. The best per-milligram value is the 100mg vial from Modified Aminos.

Retatrutide is stocked in 6 sizes: 6mg, 10mg, 12mg, 15mg, 20mg, and 24mg vials. Because vials of different strengths rarely scale linearly in price, the per-milligram column is the only fair way to rank them.

Ranked by true cost per milligram, the Retatrutide listings WPA tracks are: Modified Aminos — 100mg at $251.99 ($2.52/mg), COA purity 99.80%; Glow Aminos — 60mg at $154.11 ($2.57/mg), COA purity 99.69%; Flawless Compounds — 60mg at $154.11 ($2.57/mg), COA purity 99.69%; Southern Aminos — 30mg at $86.19 ($2.87/mg), COA purity 99.39%; Ascension Peptides — 30mg at $87.50 ($2.92/mg), COA purity 99.83%.

Retatrutide COA Coverage Across Tracked Vendors

41 of the 45 tracked Retatrutide listings (91%) publish a third-party Certificate of Analysis. Assayed purity on those reports ranges from 99.00% to 99.95%. 38 listings report more Retatrutide in the vial than the label claims, which lowers the real cost per milligram below the printed price. The most recent Retatrutide COA on file is dated 8/26. The remaining 4 listings have no published report, so its purity is the vendor's own claim.

A COA is only worth what it proves: it has to name the independent lab, be dated within the last 12 months, and match the exact Retatrutide batch and vial size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose Retatrutide

Across 60,151 Retatrutide calculator runs logged by the WPA community, the most common dose entered is 2mg, most often once weekly. The size researchers calculate against most often is the 10mg vial (17,741 runs). The most common bacteriostatic water volume is 2mL, which is what sets the draw marks on the syringe for that dose. At that dose a 24mg vial yields roughly 12 doses, so the vial size you buy decides how often you reorder as much as the price does.

Retatrutide Discount Codes

45 of the 45 tracked Retatrutide listings carry a WPA researcher discount code. The largest live discount is 50% off. Every price and per-milligram figure on this page is the post-discount number, so you are never comparing a discounted listing against an undiscounted one. Codes change and some exclude sale items or carry order minimums.

About Retatrutide

Retatrutide is the investigational triple GIP/GLP-1/glucagon agonist (Eli Lilly's LY3437943), and the research peptide drawing the most interest for next-generation weight-loss studies. It ships as a lyophilized powder reconstituted with bacteriostatic water before use.

Its reported half-life is ~6 days, which is the main reason the community cadence above looks the way it does. Not FDA-approved.

How to Read the Retatrutide Comparison

• Price per milligram — Every Retatrutide listing is normalized to $2.52/mg-style unit pricing, so a small cheap vial cannot hide a worse real cost than a larger one.
• COA status and purity — The 41 COA-backed Retatrutide listings show assayed purity and test date so quality is a number, not a claim.
• Vials sizes — All 6 stocked Retatrutide sizes (6mg, 10mg, 12mg, 15mg, 20mg, and 24mg vials) sit in one table.
• Stock status — Live in-stock state for each Retatrutide listing, refreshed on a recurring basis.

Frequently Asked Questions: Retatrutide

Is it legal and safe to buy Retatrutide for research?

In the US, Retatrutide is sold strictly as a research chemical — legal to buy for laboratory research but not approved for human use. It is an investigational triple GLP-1/GIP/glucagon receptor agonist with no approved human form anywhere in the world. The real variable isn't legality, it's quality: unverified suppliers can ship underdosed, impure, or mislabeled material. Every Retatrutide vendor in the table on this page is screened for a published third-party Certificate of Analysis (COA), which is your one objective quality check. Right now that screen covers 45 Retatrutide listings from 14 vendors.

How do I verify a Retatrutide COA so I'm not getting an underdosed vial?

A Certificate of Analysis (COA) is the third-party lab report for one specific Retatrutide batch — your only proof the vial is real and full-strength. Check four things: identity (it's actually retatrutide, not semaglutide, tirzepatide, or an underdosed mix), assay/purity (ideally 98% or higher), a named independent lab (not the vendor's own in-house claim), and a recent test date. WPA flags COA status per listing, but a marketing screenshot isn't enough — open the actual COA on the vendor's site before paying. For Retatrutide specifically, 41 of 45 tracked listings (91%) publish one, with assayed purity between 99.00% and 99.95%, the most recent dated 8/26. Every row in the table links straight to it.

Which Retatrutide vendor should I pick?

There's no single "best" Retatrutide vendor — it depends on what you weigh most. WPA ranks every verified vendor by a composite of assayed purity, COA recency, lifetime click popularity among researchers, final price, and in-stock plus discount availability. Because retatrutide is newer and pricier than other GLP-1s, COA recency and assayed purity carry extra weight — you don't want to overpay for underfilled vials. 14 vendors currently carry Retatrutide, and Modified Aminos holds the best true value at $2.52/mg on the 100mg vial. If you just want the strongest all-round value, the top-ranked Retatrutide vendor on this page is a safe starting point — but confirm its purity and price fit your protocol first.

How much does Retatrutide cost — and how do I know I'm not overpaying?

Judge Retatrutide by true price per milligram, not the sticker price on one vial — a cheap small vial often costs more per mg than a larger one. Retatrutide commonly ships in 10, 15, and 20 mg vials, and the larger sizes usually win on $/mg because a full titration needs the extra peptide anyway. Tracked Retatrutide listings currently run $2.52/mg to $13.50/mg across 6mg, 10mg, 12mg, 15mg, 20mg, 24mg vials. WPA normalizes every verified listing to $/mg, and the live cost-per-month card estimates your real spend at the most common dose, so overpaying becomes obvious at a glance. The one catch: the lowest $/mg sometimes means buying a bigger vial than your cycle needs.

How much Retatrutide do I need for one full cycle?

Retatrutide is dosed once weekly, and 2 mg is the most common dose in WPA calculator data. At 2 mg per week a single 10 mg vial covers about five weeks, while researchers running a full 8–12 week titration toward 4–8 mg typically buy a 15–20 mg vial or bundle up front. Across 60,151 Retatrutide calculator runs logged here the most common dose is 2mg once weekly; a 24mg vial covers roughly 12 of them, and that is the figure the cost-per-month card on this page is built on. Protocols vary and this reflects the most common community setup, not medical advice — research use only. Use the cost-per-month card and the calculator on this page to size your exact run, then buy enough to finish a cycle without re-ordering mid-protocol.

Are discount codes available for Retatrutide?

Yes — many verified Retatrutide vendors offer WPA researcher discount codes, and those savings are already baked into the $/mg ranking on this page, so you're never comparing a pre-discount price against a post-discount one. Codes do change, and some exclude sale items or carry order minimums. 45 of the 45 tracked Retatrutide listings carry a code right now, the largest worth 50% off. Each listing shows the current code and the discounted price where one exists.
