Semax Nasal Spray Price Comparison — Verified Vendors & Lab-Tested COAs

How much does Semax Nasal Spray cost per month?

The cheapest verified Semax Nasal Spray protocol works out to about $16.56 per month: Glow Aminos's 50 mg bottle at $91.04 with code WPA, dosed at 0.3 mg daily (the most-common community protocol). One bottle provides 166.7 doses — about 23.8 weeks of supply at this cadence — so the per-week cost is roughly $3.82, which works out to $16.56 on a 4.33-week month. This protocol is derived from 2,023 verified Semax calculator runs logged by the WPA community. Cost scales roughly linearly with the per-spray dose and weekly frequency you choose.

Semax Nasal Spray COA Coverage Across Tracked Vendors

4 of the 5 tracked Semax Nasal Spray listings (80%) publish a third-party Certificate of Analysis. Assayed purity on those reports is 99.86%. 4 listings report more Semax in the bottle than the label claims, which lowers the real cost per milligram below the printed price. The most recent Semax Nasal Spray 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 Nasal Spray batch and bottle size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose Semax

Across 2,023 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 bottle (1,331 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 bottle yields roughly 167 doses, so the bottle size you buy decides how often you reorder as much as the price does.

Semax Nasal Spray Discount Codes

5 of the 5 tracked Semax Nasal Spray 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 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 Nasal Spray Comparison

• Price per milligram — Every Semax Nasal Spray listing is normalized to $1.82/mg-style unit pricing, so a small cheap bottle cannot hide a worse real cost than a larger one.
• COA status and purity — The 4 COA-backed Semax Nasal Spray listings show assayed purity and test date so quality is a number, not a claim.
• Bottles sizes — All 3 stocked Semax Nasal Spray sizes (5mg, 40mg, and 50mg bottles) sit in one table.
• Stock status — Live in-stock state for each Semax Nasal Spray listing, refreshed on a recurring basis.

Reading Semax Nasal Spray Listings

Nasal spray listings are ranked on total Semax per bottle, so a lower-priced bottle at a lower concentration can still be the more expensive option per milligram. Where a vendor publishes it, the mcg or mg delivered per spray is what determines how many doses a bottle actually contains.

A nasal spray COA should confirm the active ingredient's purity, and — where available — the preservative system and pH range, which do not appear on a vial COA. Intranasal delivery differs from injection in absorption kinetics, so vial protocols do not carry over.
