Retatrutide/Tirzepatide Blend COA Coverage Across Tracked Vendors

Assayed purity on those reports ranges from 99.89% to 99.90%. 2 listings report more Retatrutide/Tirzepatide Blend in the vial than the label claims, which lowers the real cost per milligram below the printed price. The most recent Retatrutide/Tirzepatide Blend COA on file is dated 8/26.

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/Tirzepatide Blend batch and vial size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose Retatrutide/Tirzepatide Blend

Across 225 Retatrutide/Tirzepatide Blend calculator runs logged by the WPA community, the most common dose entered is 5mg, most often once weekly. The size researchers calculate against most often is the 30mg vial (82 runs). The most common bacteriostatic water volume is 3mL, which is what sets the draw marks on the syringe for that dose. At that dose a 35mg vial yields roughly 7.0 doses, so the vial size you buy decides how often you reorder as much as the price does.

Retatrutide/Tirzepatide Blend Discount Codes

2 of the 2 tracked Retatrutide/Tirzepatide Blend 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/Tirzepatide Blend

Retatrutide/Tirzepatide Blend is a research-only combination sourced for weight-loss and metabolic studies that stack two of the most-studied incretin agonists — Eli Lilly's investigational triple GIP/GLP-1/glucagon agonist retatrutide and the approved dual GIP/GLP-1 agonist tirzepatide. No sponsor develops the pairing; it ships as lyophilized powder you reconstitute with bacteriostatic water before use.

Retatrutide/Tirzepatide Blend is a blend of Retatrutide and Tirzepatide, so a COA has to confirm each component separately — a single purity figure for the mixture is not enough. Retatrutide is investigational and not FDA-approved; tirzepatide is FDA-approved (Mounjaro/Zepbound) but the fixed-ratio blend is in no sponsor pipeline.

• Price per milligram — Every Retatrutide/Tirzepatide Blend listing is normalized to $3.08/mg-style unit pricing, so a small cheap vial cannot hide a worse real cost than a larger one.

Frequently Asked Questions: Retatrutide/Tirzepatide Blend

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

In the US, Retatrutide/Tirzepatide Blend is sold strictly as a research chemical — legal to buy for laboratory research but not approved for human use. Retatrutide/Tirzepatide Blend is a blend of Retatrutide and Tirzepatide, and neither the blend nor its components are approved for human use — it is sold for laboratory research only. The real variable isn't legality, it's quality: unverified suppliers can ship underdosed, impure, or mislabeled material. Every Retatrutide/Tirzepatide 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 2 Retatrutide/Tirzepatide Blend listings from 2 vendors.

How do I verify a Retatrutide/Tirzepatide 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/Tirzepatide Blend batch — your only proof the vial is real and full-strength. Check four things: identity (it's actually Retatrutide plus Tirzepatide at the stated ratio, not one component sold as the blend), 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/Tirzepatide Blend specifically, 2 of 2 tracked listings (100%) publish one, with assayed purity between 99.89% and 99.90%, the most recent dated 8/26. Every row in the table links straight to it.

Which Retatrutide/Tirzepatide Blend vendor should I pick?

There's no single "best" Retatrutide/Tirzepatide 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. 2 vendors currently carry Retatrutide/Tirzepatide Blend, and Southern Aminos holds the best true value at $3.08/mg on the 35mg vial. If you just want the strongest all-round value, the top-ranked Retatrutide/Tirzepatide Blend vendor on this page is a safe starting point — but confirm its purity and price fit your protocol first.

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

Judge Retatrutide/Tirzepatide 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. Tracked Retatrutide/Tirzepatide Blend listings currently run $3.08/mg to $4.83/mg across 35mg 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/Tirzepatide Blend do I need for one full cycle?

How much Retatrutide/Tirzepatide Blend you need depends on your dose and cadence rather than on a fixed cycle length. Across 225 Retatrutide/Tirzepatide Blend calculator runs logged here the most common dose is 5mg once weekly; a 35mg vial covers roughly 7.0 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/Tirzepatide Blend?

Yes — many verified Retatrutide/Tirzepatide 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. 2 of the 2 tracked Retatrutide/Tirzepatide 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.

How much bacteriostatic water do researchers use for a 30mg Retatrutide/Tirzepatide Blend vial?

3mL is the most common reconstitution volume for a 30mg Retatrutide/Tirzepatide Blend vial in WPA calculator data. That volume is what sets the draw marks on the syringe: change it and every subsequent measurement changes with it, even though the total Retatrutide/Tirzepatide Blend in the vial is the same. Run your own numbers in the calculator on this page before drawing.
