This protocol is derived from 186 verified Retatrutide/Cagrilintide calculator runs logged by the WPA community. Cost scales roughly linearly with the per-shot dose and weekly frequency you choose.

Ranked by true cost per milligram, the Retatrutide/Cagrilintide listings WPA tracks are: Southern Aminos — 45mg at $126.86 ($2.82/mg); Glow Aminos — 22.5mg at $88.66 ($3.94/mg), COA purity 99.98%; Flawless Compounds — 22.5mg at $88.66 ($3.94/mg), COA purity 99.98%.

Retatrutide/Cagrilintide COA Coverage Across Tracked Vendors

2 of the 3 tracked Retatrutide/Cagrilintide listings (67%) publish a third-party Certificate of Analysis. Assayed purity on those reports is 99.98%. 2 listings report more Retatrutide/Cagrilintide in the vial than the label claims, which lowers the real cost per milligram below the printed price. The most recent Retatrutide/Cagrilintide COA on file is dated 5/26. The remaining 1 listing has 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/Cagrilintide batch and vial size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose Retatrutide/Cagrilintide

Across 186 Retatrutide/Cagrilintide 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 12mg vial (82 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 45mg vial yields roughly 23 doses, so the vial size you buy decides how often you reorder as much as the price does.

3 of the 3 tracked Retatrutide/Cagrilintide listings carry a WPA researcher discount code. The largest live discount is 15% off.

Codes change and some exclude sale items or carry order minimums.

About Retatrutide/Cagrilintide

Retatrutide/Cagrilintide is a research-only blend most often sourced for weight-loss and metabolic studies that pair incretin and amylin pharmacology in one protocol — Eli Lilly's investigational triple GIP/GLP-1/glucagon agonist retatrutide alongside Novo Nordisk's amylin analog cagrilintide. No sponsor markets it as a fixed-ratio drug; it ships as lyophilized powder you reconstitute with bacteriostatic water before use.

Retatrutide/Cagrilintide is a blend of Cagrilintide and Retatrutide, so a COA has to confirm each component separately — a single purity figure for the mixture is not enough. Its reported half-life is ~6 days (retatrutide-driven), which is the main reason the community cadence above looks the way it does. Neither component is FDA-approved.

How to Read the Retatrutide/Cagrilintide Comparison

Frequently Asked Questions: Retatrutide/Cagrilintide

Is it legal and safe to buy Retatrutide/Cagrilintide Blend for research?

In the US, Retatrutide/Cagrilintide Blend is sold strictly as a research chemical — legal to buy for laboratory research but not approved for human use. Both peptides are investigational with no approved human form, and the pre-combined blend is sold for laboratory use only. The real variable isn't legality, it's quality: unverified suppliers can ship underdosed, impure, or mislabeled material. Every Retatrutide/Cagrilintide Blend 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 3 Retatrutide/Cagrilintide Blend listings from 3 vendors.

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

A Certificate of Analysis (COA) is the third-party lab report for one specific Retatrutide/Cagrilintide Blend batch — your only proof the vial is real and full-strength. Check four things: identity (it's both retatrutide and cagrilintide at the labeled ratio, not just one of the two 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/Cagrilintide Blend specifically, 2 of 3 tracked listings (67%) publish one, with assayed purity of 99.98%, the most recent dated 5/26. Every row in the table links straight to it.

Which Retatrutide/Cagrilintide Blend vendor should I pick?

There's no single "best" Retatrutide/Cagrilintide Blend 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. For a blend, COA identity matters double — a good vendor's COA confirms both peptides are present at the stated amounts, and blend ratios drift if formulation isn't tightly controlled. 3 vendors currently carry Retatrutide/Cagrilintide Blend, and Southern Aminos holds the best true value at $2.82/mg on the 45mg vial. If you just want the strongest all-round value, the top-ranked Retatrutide/Cagrilintide Blend vendor on this page is a safe starting point — but confirm its purity and price fit your protocol first.

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

Judge Retatrutide/Cagrilintide Blend 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. It is usually sold as a single combined vial, and buying the two peptides pre-blended is normally cheaper than sourcing them separately. Tracked Retatrutide/Cagrilintide Blend listings currently run $2.82/mg to $3.94/mg across 22.5mg, 45mg 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/Cagrilintide Blend do I need for one full cycle?

This blend is dosed once weekly, and 1 mg is the most common dose in WPA data. At 1 mg per week a single 12.5 mg blend vial covers about twelve weeks, so one vial typically carries an early titration cycle. Across 186 Retatrutide/Cagrilintide Blend calculator runs logged here the most common dose is 2mg once weekly; a 45mg vial covers roughly 23 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/Cagrilintide Blend?

Yes — many verified Retatrutide/Cagrilintide Blend 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. 3 of the 3 tracked Retatrutide/Cagrilintide Blend listings carry a code right now, the largest worth 15% off. Each listing shows the current code and the discounted price where one exists.
