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 Selank/Semax Blend Nasal Spray batch and bottle size on sale. Open the linked report before ordering rather than trusting the badge.

How Researchers Actually Dose Selank/Semax Blend

Across 263 Selank/Semax Blend calculator runs logged by the WPA community, the most common dose entered is 500mcg, most often daily (7x/week). The size researchers calculate against most often is the 10mg bottle (135 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 20mg bottle yields roughly 40 doses, so the bottle size you buy decides how often you reorder as much as the price does.

Selank/Semax Blend Nasal Spray Discount Codes

2 of the 2 tracked Selank/Semax Blend Nasal Spray listings carry a WPA researcher discount code. The largest live discount is 10% 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 Selank/Semax Blend

The Selank/Semax Blend is a research-grade combination of two Russian heptapeptides — Selank (an anxiolytic tuftsin analog) and Semax (a nootropic ACTH(4-10) analog) — packaged in one vial and most often sourced for "calm-and-focused" cognitive research. It ships as a lyophilized powder you reconstitute with bacteriostatic water. See the standalone [Selank](/vendors/selank) and [Semax](/vendors/semax) entries for full pharmacology.

Selank/Semax Blend is a blend of Selank and Semax, so a COA has to confirm each component separately — a single purity figure for the mixture is not enough. Its reported half-life is ~30 min (both components), which is the main reason the community cadence above looks the way it does. Not FDA-approved.

Reading Selank/Semax Blend Nasal Spray Listings

Nasal spray listings are ranked on total Selank/Semax Blend 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.
