Two Russian-developed research peptides pre-mixed in a single vial, one nootropic-classified and one anxiolytic-classified. Sold both as an injectable blend and as a nasal spray preparation.
Semax + Selank is a blends peptide. Two Russian-developed research peptides pre-mixed in a single vial, one nootropic-classified and one anxiolytic-classified. Sold both as an injectable blend and as a nasal spray preparation. This page covers what it is, how it is stored and how to keep your own records — it does not recommend doses.
What Semax + Selank is
Semax is a synthetic heptapeptide derived from ACTH(4-10) with an added proline-glycine-proline sequence, primarily known for its nootropic and neuroprotective effects through modulating brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3), as well as influencing monoamine neurotransmitter systems. Selank, a synthetic tuftsin analog, primarily exerts anxiolytic and immunomodulatory effects by influencing the GABAergic system and inhibiting the enzymatic degradation of enkephalins. When combined, the blend aims to leverage Semax's cognitive and neuroprotective actions with Selank's mood-regulating and anxiolytic properties. While each peptide has a relatively short half-life in the bloodstream, their downstream effects on gene expression and neurotransmitter pathways can lead to more prolonged functional changes within the central nervous system. This combination is posited to offer a comprehensive approach to cognitive function and stress response modulation.
Researchers exploring Semax + Selank typically observe initial anxiolytic effects attributed to Selank within days, with the full spectrum of cognitive enhancement from Semax potentially manifesting over several weeks of consistent administration. Due to their complementary mechanisms, this blend is often explored as a standalone research compound, though some investigations might combine it with other agents targeting distinct pathways with careful consideration. Typical research cycles range from two to six weeks, followed by a period of discontinuation. This peptide blend is strictly for research purposes and not intended for diagnostic, preventive, or therapeutic use in humans.

What people track
Because individual responses vary so much, the useful thing is your own record: what you logged and when, how much is left in the vial, and how your chosen metrics move over the weeks. Peptide Wizard keeps all of that in one place, alongside a 3D reference vial for Semax + Selank.
FAQ
What is Semax + Selank?
Two Russian-developed research peptides pre-mixed in a single vial, one nootropic-classified and one anxiolytic-classified. Sold both as an injectable blend and as a nasal spray preparation.
Is Semax + Selank a peptide?
Yes — Semax + Selank is a peptide, meaning a short chain of amino acids. Peptides are usually handled as a freeze-dried powder that is mixed with bacteriostatic water before use.
Is Semax + Selank a steroid?
No. Semax + Selank is not an anabolic steroid. Steroids are fat-soluble hormones built on a four-ring cholesterol backbone; peptides are chains of amino acids and work by signalling to receptors rather than acting directly on DNA in the same way.
What do people commonly report with Semax + Selank?
Commonly reported effects include combined in one vial, single reconstitution, one shared shelf life.
How should Semax + Selank be stored?
Store as directed by the supplier, protected from light and heat.
How do I keep track of Semax + Selank in my research log?
Peptide Wizard lets you record each entry, keep a vial ledger so you know what's left, and chart your own metrics over time. It is a logbook and reference only — it does not calculate or recommend doses.
How long does Semax + Selank last once it is mixed?
As a general convention a reconstituted vial is treated as good for around 28 days refrigerated at 2-8 C, roughly 60 days frozen, and only a few days at room temperature. That figure comes from standard practice for preserved multi-dose vials rather than a test on any single compound, so the instructions supplied with your own vial take precedence. There is a full storage guide at peptidewizard.app/guides/storage/.
Is Semax + Selank taken orally or by injection?
Semax + Selank is generally handled as subq or nasal, per supplier. Sealed powder is normally kept refrigerated or frozen and mixed with bacteriostatic water when it is going to be used.
What is the difference between Semax + Selank and a steroid or a hormone drug?
Semax + Selank is a chain of amino acids that signals to receptors. Anabolic steroids are fat-soluble hormones built on a cholesterol backbone and behave completely differently in the body. Neither this page nor the app provides guidance on using either.
How much does Semax + Selank cost per dose?
Divide what you paid for the vial by the number of doses in it. A 10 mg vial contains 10 mg, or 10000 mcg, so the number of doses depends entirely on the amount you use. The calculator on this page does the arithmetic, including the doses you lose if the vial expires first.
Is a bigger Semax + Selank vial cheaper?
Per milligram, usually yes. Per dose you actually use, not always — a larger vial you cannot finish inside its stability window can work out more expensive than a smaller one you do finish, because the leftover doses were still paid for.
Why is my real cost higher than price divided by doses?
Because a reconstituted vial has a limited usable window, commonly quoted as around 28 days refrigerated. Doses still in the vial when that window closes are wasted, so the honest figure is the price divided by the doses you reach in time.
How long does Semax + Selank last once mixed?
Commonly quoted at around 28 days when kept refrigerated. Frozen extends that considerably, provided you freeze it once rather than thawing and refreezing. At room temperature you are counting in days. Purity, buffers and preservatives all change the answer, so the information supplied with your own vial takes precedence.
Does Semax + Selank need to be refrigerated?
Once reconstituted, refrigeration is the normal recommendation, and heat is by far the biggest cause of degradation. Sealed lyophilized powder is more tolerant but still keeps best cold and away from light.
Can I freeze Semax + Selank?
Freezing once is generally considered fine and extends the usable window. Repeated freeze-thaw cycles are what cause damage, so splitting into smaller amounts before freezing means you only thaw what you need.
How do I tell how old my Semax + Selank vial is?
Write the date you mixed it on the vial, or record it in a tracking app. Without that date there is no reliable way to know, which is the most common reason a vial gets used past its window or thrown away early.
What a dose of Semax + Selank costs
Vials are priced per vial, but you use them per dose. Semax + Selank is most commonly sold as a 10 mg presentation. Put in what you paid and the amount you use, and this works out the real figure — including the doses you lose if the vial expires before you finish it. Nothing is stored or sent anywhere.
Reference arithmetic only. The dose figure is whatever you enter — this site does not suggest one.
A smaller vial sometimes works out cheaper per dose than a larger one, even when the larger one looks better per milligram, because a vial you cannot finish inside its stability window still had to be paid for in full. If the box above shows waste, try a smaller vial size and watch the real figure move.
How long Semax + Selank lasts once mixed
The clock starts when you mix it. Reconstituted Semax + Selank is generally quoted at around 28 days refrigerated, roughly 60 days frozen if frozen only once, and a few days at room temperature. Sealed powder keeps far longer. Enter the date you mixed it for an exact expiry date.
Reference only — purity, buffers and preservatives all change the answer, so the storage information supplied with your own vial takes precedence. Full method and sources in the shelf life reference table.
Four things do the damage, in rough order: heat by a wide margin, then light, then repeated freeze–thaw cycles, then agitation. Swirl a vial to mix it rather than shaking it, and keep it in its box away from light.
