About Selank
What is Selank?
Overview
What is Selank?
Selank is a synthetic heptapeptide derived from the endogenous immunomodulatory peptide tuftsin, extended with a proline-glycine-proline tail that improves stability against enzymatic degradation. It is supplied as a lyophilised powder in sealed vials, boxed in tens, for laboratory research use only.

These are catalogue target specifications, not batch results. The 99%+ purity figure is the specification we buy to. The authoritative figures for any particular box are the ones printed on that box’s Certificate of Analysis, which is lot-specific. What research grade actually means explains the difference. Terms such as HPLC purity and net peptide content are explained in the peptide glossary.
We make no “third-party verified” claim for a batch unless the matching report is supplied with it. Ask for the current COA for the lot in stock before you order — we will send it.

Storage & reconstitution
Handling
How should Selank be stored and reconstituted?
Sealed vials tolerate ambient temperature in transit and keep at −20 °C beyond that. Reconstitute slowly down the vial wall, swirl rather than shake, then refrigerate at 2–8 °C and aliquot before freezing.
Why each of those matters, and what a freeze–thaw cycle actually costs: peptide handling and storage reference. How long a mixed vial keeps: reconstituted peptide shelf life.
What it is researched for
Research Context
What is Selank researched for?
Below is a plain-English summary of what published research has investigated, and what it has found. These are descriptions of research activity and published results. They are not claims about what Selank does, and nothing here is a statement that it is safe or effective for any purpose.
Anxiolytic research
Selank was developed from tuftsin as an anxiolytic candidate, and interest persists because it is reported to act without the sedation, tolerance or dependence associated with benzodiazepines. The main published human study compared it directly against the benzodiazepine medazepam in generalized anxiety disorder and neurasthenia, reporting a comparable anxiolytic effect with additional antiasthenic and psychostimulant activity. 1 That is a 62-patient Russian-language trial which has not been independently replicated, and it carries correspondingly less weight than the journal listing alone suggests.
GABA and serotonin systems
Animal work reports changes in the expression of GABA-A receptor subunits and in serotonin turnover, and these are the pathways most commonly proposed to explain the behavioural observations. Rodent work also reports that Selank attenuates the aversive signs of naloxone-precipitated morphine withdrawal, performing close to but below diazepam in the same model. 2
Peptide stability design
Tuftsin itself is cleared almost immediately. Adding Pro-Gly-Pro to the C-terminus slows that enough to make the molecule usable, the same approach taken with Semax. It is a clean illustration of how terminal extensions protect very short peptides.

Batch COA
Verification
Does Selank come with a COA?
Yes — every box. Each batch of Selank is analysed by an independent third-party laboratory, and the certificate is tied to the batch number on the vial label.

Questions & answers
Questions
Selank questions, answered
What is Selank derived from?
Selank is built on tuftsin, a naturally occurring tetrapeptide fragment of immunoglobulin G. The addition of a Pro-Gly-Pro tail at the C-terminus substantially slows enzymatic cleavage, which is the same stabilising strategy used in Semax.
How much does Selank cost?
Selank starts at $6.51 per vial, sold in boxes of 10 vials at $65.14 per box (about £48.80). 2 strengths available: 5 mg, 10 mg. There is no minimum order.
Can I buy Selank 10mg vials in the UK?
Yes. Selank 10mg comes in boxes of 10 vials at $80.14 per box ($8.01 per vial, about £60.04 per box), sent tracked to UK addresses. There is no minimum order.
How is Selank shipped to the UK and USA?
Tracked to the UK, USA, EU and worldwide, in plain packaging, dispatched within 1–2 working days. Country-by-country estimates are on the shipping page.
