Retatrutide/Cagrilintide COA Coverage Across Tracked Vendors

5 of the 5 tracked Retatrutide/Cagrilintide listings (100%) are marked as having COA availability in WPA's listing data; this marker is not independent verification. A purity value is recorded for 4 listings; purity alone does not establish identity or independent testing. The recorded purity values range from 99.00% to 99.98%. 5 listings record more Retatrutide/Cagrilintide in the vial than the label claims; check the vendor's report and batch before drawing conclusions. The latest COA date recorded in WPA's listing data is 7/26.

To assess a COA, inspect the actual report for the independent lab, test date, and a batch and vial size matching the Retatrutide/Cagrilintide offer. WPA's listing fields do not establish that a report was independently verified.

How Researchers Actually Dose Retatrutide/Cagrilintide

Across 233 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 (97 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.

Retatrutide/Cagrilintide Discount Codes

5 of the 5 tracked Retatrutide/Cagrilintide listings carry a WPA researcher discount code. The largest live discount is 15% 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/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.

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. WPA records COA-related listing fields where supplied, but does not independently verify every report. Inspect the actual batch report and its laboratory, identity testing, and date before drawing conclusions. Right now that screen covers 5 Retatrutide/Cagrilintide Blend listings from 5 vendors.

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

A Certificate of Analysis (COA) may report tests for a specific Retatrutide/Cagrilintide Blend batch. Check that the report identifies the compound (both retatrutide and cagrilintide at the labeled ratio, not just one of the two or an underdosed mix), names the laboratory, describes the test method and result, and matches the offered batch and date. A recorded purity value or COA-availability flag in WPA's listing data is not independent verification. Open the vendor listing and inspect the actual report before drawing conclusions. For Retatrutide/Cagrilintide Blend specifically, 5 of 5 tracked listings (100%) are marked as having COA availability in WPA's listing data; that marker is not independent verification. A purity value is separately recorded for 4 listings; purity alone does not establish identity or independent testing. The latest COA date recorded in the listing data is 7/26.

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 tracked listings using recorded purity and date fields where available, visitor click activity, price, stock status, and discount data; this ranking is not independent verification of a report. 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. 5 vendors currently carry Retatrutide/Cagrilintide Blend, and Southern Aminos holds the best true value at $2.82/mg on the 45mg vial. Review the actual report and confirm its batch details before making a decision.

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 $7.08/mg across 15mg, 22.5mg, 45mg vials. WPA normalizes tracked listings to $/mg, and the live cost-per-month card estimates your spend at the most common dose. 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 233 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. 5 of the 5 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.
