Tirzepatide Peptide Sale

How much does Tirzepatide cost per month?

The cheapest verified Tirzepatide protocol works out to about $16.68 per month: Flawless Compounds's 100 mg vial at $154.11 with code WPA, dosed at 2.5 mg once weekly (the most-common community protocol). One vial provides 40.0 doses — about 40.0 weeks of supply at this cadence — so the per-week cost is roughly $3.85, which works out to $16.68 on a 4.33-week month. This protocol is derived from 14,131 verified Tirzepatide 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 Tirzepatide Costs Right Now

WPA currently tracks Tirzepatide at 14 verified vendors across 57 separate Tirzepatide listings. In-stock Tirzepatide vials run from $25 to $1259.99 — a 50.4x spread for the same compound. Ascension Peptides holds the lowest sticker price at $25. Normalized to milligrams, Tirzepatide costs $1.54/mg to $12.11/mg on this page. The best per-milligram value is the 100mg vial from Flawless Compounds.

Tirzepatide is stocked in 6 sizes: 10mg, 12mg, 15mg, 20mg, 30mg, and 40mg 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 Tirzepatide listings WPA tracks are: Flawless Compounds — 100mg at $154.11 ($1.54/mg), COA purity 99.85%; Glow Aminos — 100mg at $154.11 ($1.54/mg), COA purity 99.85%; Southern Aminos — 60mg at $101.36 ($1.69/mg), COA purity 99.94%; Ascension Peptides — 30mg at $55 ($1.83/mg), COA purity 99.82%; Southern Aminos — 40mg at $82.24 ($2.06/mg).

Tirzepatide COA Coverage Across Tracked Vendors

46 of the 57 tracked Tirzepatide listings (81%) publish a third-party Certificate of Analysis. Assayed purity on those reports ranges from 99.00% to 99.97%. 40 listings report more Tirzepatide in the vial than the label claims, which lowers the real cost per milligram below the printed price. The most recent Tirzepatide COA on file is dated 6/26. The remaining 11 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 Tirzepatide batch and vial size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose Tirzepatide

Across 14,131 Tirzepatide calculator runs logged by the WPA community, the most common dose entered is 2.5mg, most often once weekly. The size researchers calculate against most often is the 30mg vial (3,684 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 40mg vial yields roughly 16 doses, so the vial size you buy decides how often you reorder as much as the price does.

Tirzepatide Discount Codes

57 of the 57 tracked Tirzepatide 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 Tirzepatide

Tirzepatide is the dual GIP/GLP-1 receptor agonist behind Mounjaro and Zepbound, and the research peptide most often sourced for weight-management and metabolic studies. It ships as a lyophilized powder you reconstitute with bacteriostatic water before use.

Its reported half-life is ~5 days, which is the main reason the community cadence above looks the way it does. FDA-approved as Mounjaro (T2D, 2022) and Zepbound (obesity, 2023).

Frequently Asked Questions: Tirzepatide

Is it legal and safe to buy Tirzepatide for research?

In the US, Tirzepatide is sold strictly as a research chemical — legal to buy for laboratory research but not approved for human use. It is the same molecule as the approved GLP-1/GIP drug, but research-grade vials are not FDA-approved and are sold for laboratory use only. The real variable isn't legality, it's quality: unverified suppliers can ship underdosed, impure, or mislabeled material. Every Tirzepatide 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 57 Tirzepatide listings from 14 vendors.

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

A Certificate of Analysis (COA) is the third-party lab report for one specific Tirzepatide batch — your only proof the vial is real and full-strength. Check four things: identity (it's actually tirzepatide, not semaglutide or an underdosed 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 Tirzepatide specifically, 46 of 57 tracked listings (81%) publish one, with assayed purity between 99.00% and 99.97%, the most recent dated 6/26. Every row in the table links straight to it.

Which Tirzepatide vendor should I pick?

There's no single "best" Tirzepatide 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. Tirzepatide is one of the most-bought compounds on the site, so lifetime click data is especially meaningful here — but always cross-check the COA date, since high-volume sellers rotate batches often. 14 vendors currently carry Tirzepatide, and Flawless Compounds holds the best true value at $1.54/mg on the 100mg vial. If you just want the strongest all-round value, the top-ranked Tirzepatide vendor on this page is a safe starting point — but confirm its purity and price fit your protocol first.

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

Judge Tirzepatide 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 ships in everything from 10 mg up to 60 mg vials, and the big multi-dose vials dramatically lower $/mg over a full titration cycle. Tracked Tirzepatide listings currently run $1.54/mg to $12.11/mg across 10mg, 12mg, 15mg, 20mg, 30mg, 40mg 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 Tirzepatide do I need for one full cycle?

Tirzepatide is dosed once weekly, starting around 2.5 mg in WPA data and titrating up to 5, 7.5, 10 mg and beyond. At 2.5 mg per week a 30 mg vial covers about 12 weeks, but a cycle that ramps the dose burns through it faster, so many researchers buy a larger vial or bundle to cover a full titration without re-ordering. Across 14,131 Tirzepatide calculator runs logged here the most common dose is 2.5mg once weekly; a 40mg vial covers roughly 16 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 Tirzepatide?

Yes — many verified Tirzepatide 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. 57 of the 57 tracked Tirzepatide listings carry a code right now, the largest worth 50% off. Each listing shows the current code and the discounted price where one exists.
