Selank is a synthetic heptapeptide studied in experimental models involving neurochemical signaling, cognitive processes, stress-response pathways, and central nervous system activity.
Neurochemical Research
Investigated for its interactions with neurochemical signaling pathways within the central nervous system.
Cognitive Research
Studied in experimental models examining learning, memory, and other cognitive processes.
Stress-Response Pathways
Researched for its relationship with biological pathways involved in experimental stress responses.
CNS Signaling
Used in laboratory research exploring signaling mechanisms and regulatory processes within the central nervous system.
What Selank is
Selank is a short synthetic peptide based on a fragment of tuftsin, an immunologically active fragment of an antibody heavy chain, with a stabilising extension added to slow peptidase degradation.
It is routinely mentioned in the same breath as Semax because both came from the same research programme and both use the same trick of extending an endogenous fragment. The parent molecules are unrelated, and treating the two as interchangeable is the most common mistake made with them.
Handling and reconstituting Selank
Standard lyophilised peptide handling applies. Keep the sealed vial cold and dark until it is used. Reconstitute by running bacteriostatic water slowly down the inside wall of the vial rather than firing it onto the powder cake, and let it dissolve without shaking — swirl gently if it needs help.
The concentration you end up with is set by how much water you add, not by the vial size. Our reconstitution calculator turns vial mass and water volume into a concentration and a syringe reading.
Storage
Sealed and lyophilised: refrigerated, protected from light. In solution: refrigerated, and treat time at room temperature as a cost. Avoid repeated freeze-thaw once reconstituted.
What ships, and what is on the certificate
The vial ships sealed as it was filled. Every compound in the catalogue is tested by an outside laboratory — Vanguard Laboratory in Olympia, Washington — and the certificate is published in full rather than summarised.
The certificate reports chromatographic purity by HPLC with the chromatogram visible, the measured quantity in milligrams, and an endotoxin result by LAL. Measured quantity usually reads slightly above the label, which is normal: fills are targeted high so every vial meets its stated content.
Frequently asked questions
What is Selank based on?
A fragment of tuftsin, itself a fragment of an antibody heavy chain, with added residues to slow degradation.
Is it interchangeable with Semax?
No. They share an origin and a design approach but derive from different parent molecules and are studied for different things.
How should it be reconstituted?
Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve without shaking. The reconstitution calculator will convert vial mass and water volume into a concentration and a syringe reading.
Does it come with a certificate of analysis?
Yes. Every compound is tested by an independent laboratory and the full certificate, chromatogram included, is published on the site rather than summarised.
Is this a medicine?
No. It is sold for in-vitro laboratory research use only. It is not a drug, supplement or cosmetic, and is not for human or veterinary use.
