Semax Peptide For Sale

How much does Semax cost per month?

The cheapest verified Semax protocol works out to about $15.46 per month: Limitless Biotech's 30 mg vial at $50.99 with code WPA, dosed at 0.3 mg daily (the most-common community protocol). One vial provides 100.0 doses — about 14.3 weeks of supply at this cadence — so the per-week cost is roughly $3.57, which works out to $15.46 on a 4.33-week month. This protocol is derived from 1,993 verified Semax 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 Semax Costs Right Now

WPA currently tracks Semax at 14 verified vendors across 15 separate Semax listings. In-stock Semax vials run from $26.18 to $66.56 — a 2.5x spread for the same compound. Flawless Compounds holds the lowest sticker price at $26.18. Normalized to milligrams, Semax costs $1.70/mg to $6.48/mg on this page. The best per-milligram value is the 30mg vial from Limitless Biotech.

Semax is stocked in 4 sizes: 5mg, 10mg, 20mg, and 30mg 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 Semax listings WPA tracks are: Limitless Biotech — 30mg at $50.99 ($1.70/mg), COA purity 99.00%; Limitless Biotech — 20mg at $36.93 ($1.85/mg), COA purity 99.00%; Paramount Peptides — 30mg at $64.60 ($2.15/mg), COA purity 99.14%; Swiss Chems — 30mg at $66.56 ($2.22/mg); Flawless Compounds — 10mg at $26.18 ($2.62/mg), COA purity 99.42%.

Semax COA Coverage Across Tracked Vendors

14 of the 15 tracked Semax listings (93%) publish a third-party Certificate of Analysis. Assayed purity on those reports ranges from 99.00% to 99.89%. 9 listings report more Semax in the vial than the label claims, which lowers the real cost per milligram below the printed price. The most recent Semax COA on file is dated 6/26. The remaining 1 listing has 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 Semax batch and vial size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose Semax

Across 1,993 Semax calculator runs logged by the WPA community, the most common dose entered is 300mcg, most often daily (7x/week). The size researchers calculate against most often is the 10mg vial (1,307 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 30mg vial yields roughly 100 doses, so the vial size you buy decides how often you reorder as much as the price does.

Semax Discount Codes

15 of the 15 tracked Semax 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 Semax

Semax is a nootropic and neuroprotective research peptide most often sourced for focus, cognition, and recovery protocols, and used intranasally. It ships as a lyophilized powder you reconstitute with bacteriostatic water before use.

Its reported half-life is ~30 min, which is the main reason the community cadence above looks the way it does. Not FDA-approved.

How to Read the Semax Comparison

• Price per milligram — Every Semax listing is normalized to $1.70/mg-style unit pricing, so a small cheap vial cannot hide a worse real cost than a larger one.
• COA status and purity — The 14 COA-backed Semax listings show assayed purity and test date so quality is a number, not a claim.
• Vials sizes — All 4 stocked Semax sizes (5mg, 10mg, 20mg, and 30mg vials) sit in one table.
• Stock status — Live in-stock state for each Semax listing, refreshed on a recurring basis.

Frequently Asked Questions: Semax

Is it legal and safe to buy Semax for research?

In the US, Semax is sold strictly as a research chemical — legal to buy for laboratory research but not approved for human use. Semax is approved in Russia for some uses but has no FDA approval, so research vials 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 Semax 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 15 Semax listings from 14 vendors.

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

A Certificate of Analysis (COA) is the third-party lab report for one specific Semax batch — your only proof the vial is real and full-strength. Check four things: identity (it's actually semax, not the longer-acting N-acetyl (NA-Semax) version or a Selank/Semax 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 Semax specifically, 14 of 15 tracked listings (93%) publish one, with assayed purity between 99.00% and 99.89%, the most recent dated 6/26. Every row in the table links straight to it.

Which Semax vendor should I pick?

There's no single "best" Semax 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. Semax is also sold as a nasal spray and pre-blended with selank, so confirm the COA matches the plain injectable form if that's what you want. 14 vendors currently carry Semax, and Limitless Biotech holds the best true value at $1.70/mg on the 30mg vial. If you just want the strongest all-round value, the top-ranked Semax vendor on this page is a safe starting point — but confirm its purity and price fit your protocol first.

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

Judge Semax 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 most often ships in 10 mg vials, so compare $/mg across those before assuming the cheapest vial is the best value. Tracked Semax listings currently run $1.70/mg to $6.48/mg across 5mg, 10mg, 20mg, 30mg 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 Semax do I need for one full cycle?

Semax is typically dosed once daily, and 300 mcg is the most common dose in WPA data. At 300 mcg per day a single 10 mg vial covers about a month, so one vial comfortably carries a standard 4-week cognitive cycle. Across 1,993 Semax calculator runs logged here the most common dose is 300mcg daily (7x/week); a 30mg vial covers roughly 100 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 Semax?

Yes — many verified Semax 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. 15 of the 15 tracked Semax listings carry a code right now, the largest worth 50% off. Each listing shows the current code and the discounted price where one exists.
