Description

Selank

Selank – 11mg (Lyophilized Peptide) – For Research Use Only

Selank is a synthetic peptide analog of the naturally occurring tetrapeptide Tuftsin, extensively studied for its potential nootropic, anxiolytic, and immunomodulatory properties. Research suggests that Selank may support cognitive function, anxiety reduction, and immune system regulation through its interaction with neurotransmitter systems, particularly GABA and serotonin pathways.

Product Details:

  • Peptide: Selank (Tuftsin analog)

  • Purity: >98%

  • Form: Lyophilized powder

  • Quantity: 11mg per vial

  • Storage: Store at -4°F (-20°C). After reconstitution, refrigerate at 36–46°F (2–8°C) and use within 30 days.

  • Grade: For research purposes only. Not for human consumption, therapeutic, or diagnostic use.

Potential Research Applications:

  • Nootropic and cognitive function studies

  • Anxiolytic and mood regulation research

  • Immune modulation and cytokine balance exploration

  • Neurotransmitter activity and brain health models


For laboratory research only. This product is not intended to diagnose, treat, cure, or prevent any disease.

Description + COA

Selank peptide​ Details

Selank is a synthetic analog of the endogenous immunomodulatory peptide tuftsin, developed by the same Russian research group responsible for Semax. Structurally extended for metabolic stability, Selank has been studied primarily for its anxiolytic (anti-anxiety) and nootropic properties without the sedation or dependency profile associated with benzodiazepine-class compounds. Research has examined its effect on GABAergic tone, monoamine (serotonin/dopamine) balance, and expression of BDNF, positioning it as a peptide of interest for stress modulation, emotional regulation, and cognitive resilience under pressure. As with Semax, Selank carries an existing regulatory registration in Russia as a prescription nasal-spray anxiolytic, and much of the peer-reviewed literature originates from that clinical context, with an expanding body of international preclinical research into its neuroimmune signaling properties.

Research

Selank peptide​ Scientific Research

  1. GABAergic System Modulation
    Selank is widely used in studies investigating central GABA-A receptor signaling. It is evaluated for its ability to influence inhibitory synaptic tone and neuroplasticity-related mechanisms in rodent brain tissue models.
  2. Neuroimmune Regulation and Cytokine Activity
    In controlled in-vitro systems and in-vivo experiments, Selank has been shown to alter the expression of interleukins such as IL-6 and modulate pathways associated with immune–neural crosstalk, particularly in inflammation and stress-related studies.
  3. Neurotransmitter-Linked Gene Expression
    Selank is investigated for its transcriptional influence on BDNF and other genes associated with dopaminergic and serotonergic systems. Researchers often measure its effects on enkephalin-degrading enzymes and monoamine metabolism.
  4. Stress Response and Behavioral Studies
    Rodent behavioral paradigms using Selank include elevated plus maze, open field, and restraint stress tests, aimed at exploring peptide-based regulation of anxiety and emotional behavior under CNS-relevant conditions.

5. Peptide Stability and Pharmacodynamics
Due to its synthetic structure and neurobiological relevance, Selank is utilized in pharmacokinetic and receptor engagement studies, especially those analyzing long-acting peptide stability in biological systems.

Storage & handling

Handled correctly, stability holds

All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.

01 — ON ARRIVAL

Store vials in a cool, dry place away from heat and direct sunlight.

02 — LONG-TERM (POWDER)

For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.

03 — AFTER RECONSTITUTION

Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.

NOTE

Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.

FAQ

Frequently Asked Questions

PRODUCT & PURITY

This product is offered for laboratory and research use only. It is not intended for human consumption, medical use, therapeutic use, or veterinary use.

Yes, all of our products are sterile and sealed with a sterility plug and safety cap.

Our products undergo quality control internally at our lab and then 3rd party tested at Bioviridian (at their Texas facility) prior to shipment. All of our COA's are then posted on our site immediately upon receipt.

99% or higher. Period. The expected purity is listed on the individual product page or Certificate of Analysis, when available.

No. We are a manufacturing company and because these products are sold for research purposes only, we do not provide dosing, administration, or medical-use guidance.

Unless specifically stated otherwise, these products are not approved by the U.S. Food and Drug Administration for therapeutic or diagnostic use.

STORAGE & STABILITY

As a lyophilized powder, peptides are stable. Delays in shipments up to 7 days will have zero to minimal impact on efficacy of peptides. Most precautionary efforts must be made to maintain temperature consistency once reconstituted.

Store the product according to the storage recommendations provided on the label or accompanying documentation in your shipment. Proper storage helps maintain product integrity during its shelf life. Most peptides have an expiration date of 2 years if kept unreconstituted (lyophilized powder).

SHIPPING

Shipping times vary based on your location and the shipping method selected at checkout. We offer shipping options between 1 and 5 days.
