How much does Semaglutide cost per month?

The cheapest verified Semaglutide protocol works out to about $5.02 per month: Flawless Compounds's 10 mg vial at $38.67 with code WPA, dosed at 0.3 mg once weekly (the most-common community protocol). One vial provides 33.3 doses — about 33.3 weeks of supply at this cadence — so the per-week cost is roughly $1.16, which works out to $5.02 on a 4.33-week month. This protocol is derived from 5,288 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 at 13 verified vendors across 28 separate Semaglutide listings. In-stock Semaglutide vials run from $20 to $494.99 — a 24.7x spread for the same compound. Ascension Peptides holds the lowest sticker price at $20. Normalized to milligrams, Semaglutide costs $3.87/mg to $32.30/mg on this page. The best per-milligram value is the 10mg vial from Flawless Compounds.

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: Flawless Compounds — 10mg at $38.67 ($3.87/mg), COA purity 99.79%; Glow Aminos — 10mg at $38.67 ($3.87/mg), COA purity 99.79%; Ascension Peptides — 5mg at $20 ($4.00/mg), COA purity 99.25%; Modified Aminos — 10mg at $44.99 ($4.50/mg), COA purity 99.00%; Ameano Peptides — 10mg at $48.60 ($4.86/mg), COA purity 99.63%.

Semaglutide COA Coverage Across Tracked Vendors

23 of the 28 tracked Semaglutide listings (82%) publish a third-party Certificate of Analysis. Assayed purity on those reports ranges from 99.00% to 100.00%. 19 listings report more Semaglutide in the vial than the label claims, which lowers the real cost per milligram below the printed price. The most recent Semaglutide COA on file is dated 7/26. The remaining 5 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 Semaglutide batch and vial size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose Semaglutide

Across 5,288 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 (2,083 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.

How to Read the Semaglutide Comparison

• Price per milligram — Every Semaglutide listing is normalized to $3.87/mg-style unit pricing, so a small cheap vial cannot hide a worse real cost than a larger one.
• COA status and purity — The 23 COA-backed Semaglutide listings show assayed purity and test date so quality is a number, not a claim.
• Vials sizes — All 6 stocked Semaglutide sizes (2mg, 5mg, 10mg, 15mg, 20mg, and 50mg vials) sit in one table.
• Stock status — Live in-stock state for each Semaglutide listing, refreshed on a recurring basis.

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. Every Semaglutide 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 28 Semaglutide listings from 13 vendors.

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

A Certificate of Analysis (COA) is the third-party lab report for one specific Semaglutide batch — your only proof the vial is real and full-strength. Check four things: identity (it's actually semaglutide, not a generic GLP-1 or an underdosed substitute), 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 Semaglutide specifically, 23 of 28 tracked listings (82%) publish one, with assayed purity between 99.00% and 100.00%, the most recent dated 7/26. Every row in the table links straight to it.

Which Semaglutide vendor should I pick?

There's no single "best" Semaglutide 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. 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. 13 vendors currently carry Semaglutide, and Flawless Compounds holds the best true value at $3.87/mg on the 10mg vial. If you just want the strongest all-round value, the top-ranked Semaglutide vendor on this page is a safe starting point — but confirm its purity and price fit your protocol first.

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 $3.87/mg to $32.30/mg across 2mg, 5mg, 10mg, 15mg, 20mg, 50mg 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 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 5,288 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.

Lowest priced Semaglutide peptide for sale?

To surface the lowest priced Semaglutide for sale, WPA continuously compares 16 USA suppliers and 967 "for research" products, ranking every verified Semaglutide listing by true cost so the cheapest vials rise to the top. The lowest priced single Semaglutide vial currently starts at $20.00. We currently track 30 Semaglutide products in our system. Pricing is generally refreshed weekly as vendors update stock, prices, and discount codes.
