How much does Semaglutide cost per month?

The cheapest verified Semaglutide protocol works out to about $4.30 per month: EZ Peptides's 100 mg vial at $331.20 with code wpa10, dosed at 0.3 mg once weekly (the most-common community protocol). One vial provides 333.3 doses — about 333.3 weeks of supply at this cadence — so the per-week cost is roughly $0.99, which works out to $4.30 on a 4.33-week month. This protocol is derived from 6,097 verified Semaglutide 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 Semaglutide Costs Right Now

WPA currently tracks Semaglutide from 12 distinct vendors across 28 separate Semaglutide listings. In-stock Semaglutide vials run from $26.10 to $674.99 — a 25.9x spread for the same compound. Ameano Peptides holds the lowest sticker price at $26.10. Normalized to milligrams, Semaglutide costs $3.31/mg to $32.30/mg on this page. The best per-milligram value is the 100mg vial from EZ Peptides.

Semaglutide is stocked in 6 sizes: 2mg, 5mg, 10mg, 15mg, 20mg, and 50mg 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 Semaglutide listings WPA tracks are: EZ Peptides — 100mg at $331.20 ($3.31/mg), COA purity 99.62%; Ameano Peptides — 10mg at $34.20 ($3.42/mg), COA purity 99.63%; EZ Peptides — 10mg at $43.20 ($4.32/mg), COA purity 99.62%; Modified Aminos — 10mg at $44.99 ($4.50/mg), COA purity 99.00%; Peptira — 20mg at $101.15 ($5.06/mg), COA purity 99.77%.

Semaglutide COA Coverage Across Tracked Vendors

26 of the 28 tracked Semaglutide listings (93%) are marked as having COA availability in WPA's listing data; this marker is not independent verification. A purity value is recorded for 25 listings; purity alone does not establish identity or independent testing. The recorded purity values range from 99.00% to 100.00%. 22 listings record more Semaglutide 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 8/26.

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

How Researchers Actually Dose Semaglutide

Across 6,097 Semaglutide calculator runs logged by the WPA community, the most common dose entered is 250mcg, most often once weekly. The size researchers calculate against most often is the 10mg vial (2,432 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 50mg vial yields roughly 200 doses, so the vial size you buy decides how often you reorder as much as the price does.

Semaglutide Discount Codes

28 of the 28 tracked Semaglutide 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 Semaglutide

Semaglutide is the GLP-1 receptor agonist behind Ozempic, Wegovy, and Rybelsus, and one of the most-sourced research peptides for weight-management and metabolic studies. It ships as a lyophilized powder reconstituted with bacteriostatic water before use.

Its reported half-life is ~7 days, which is the main reason the community cadence above looks the way it does. FDA-approved as Ozempic, Wegovy, and Rybelsus.

Frequently Asked Questions: Semaglutide

Is it legal and safe to buy Semaglutide for research?

In the US, Semaglutide is sold strictly as a research chemical — legal to buy for laboratory research but not approved for human use. Research-grade semaglutide is the same peptide as the approved GLP-1 drug but is sold for laboratory use only and is not FDA-approved in this form. 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 28 Semaglutide listings from 12 vendors.

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

A Certificate of Analysis (COA) may report tests for a specific Semaglutide batch. Check that the report identifies the compound (actually semaglutide, not a generic GLP-1 or an underdosed substitute), 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 Semaglutide specifically, 26 of 28 tracked listings (93%) are marked as having COA availability in WPA's listing data; that marker is not independent verification. A purity value is separately recorded for 25 listings; purity alone does not establish identity or independent testing. The latest COA date recorded in the listing data is 8/26.

Which Semaglutide vendor should I pick?

There's no single "best" Semaglutide 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. Semaglutide is sold by nearly every vendor, so price spreads are wide — lean on the $/mg ranking and COA recency to separate genuine value from cut-rate underfilled vials. 12 vendors currently carry Semaglutide, and EZ Peptides holds the best true value at $3.31/mg on the 100mg vial. Review the actual report and confirm its batch details before making a decision.

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

Judge Semaglutide 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. Because the typical research dose is tiny, a single 10 mg vial stretches a long way, making semaglutide one of the cheapest GLP-1s per cycle. Tracked Semaglutide listings currently run $3.31/mg to $32.30/mg across 2mg, 5mg, 10mg, 15mg, 20mg, 50mg 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 Semaglutide do I need for one full cycle?

Semaglutide is dosed once weekly, and most WPA researchers start around 0.25 mg, titrating up toward 1–2 mg over months. At those low starting doses a single 10 mg vial can cover several months, which is why per-cycle it is one of the most economical GLP-1s. Across 6,097 Semaglutide calculator runs logged here the most common dose is 250mcg once weekly; a 50mg vial covers roughly 200 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 Semaglutide?

Yes — many verified Semaglutide 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. 28 of the 28 tracked Semaglutide listings carry a code right now, the largest worth 50% off. Each listing shows the current code and the discounted price where one exists.

Is research semaglutide the same as Ozempic or Wegovy?

Chemically, research-grade semaglutide is the same peptide as the active ingredient in Ozempic and Wegovy. Everything around it differs: the branded products are FDA-approved, made under pharmaceutical GMP, supplied in pre-filled pens, and prescribed with medical oversight. Research vials are sold for laboratory use only, are not FDA-approved, and come with none of that oversight — which is exactly why an independent, recent third-party COA is the one thing you should never skip.
