Selank is a synthetic heptapeptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences as a modified analogue of the endogenous tetrapeptide tuftsin. It has been the subject of extensive preclinical and clinical research into GABAergic anxiolytic mechanisms, BDNF-mediated neuroplasticity, and stress-related cognitive impairment. For a full breakdown of its mechanism of action, see our Selank research overview. For researchers in Malaysia studying anxiety biology, cognitive neuroscience, or the stress-immune axis, Selank is now accessible locally through Concept Peptides without the complications of international ordering.
Note: Selank supplied by Concept Peptides is a research-grade compound intended strictly for laboratory and preclinical research purposes. It is not for human consumption.
What Makes Selank Different
GABAergic Modulation
Research has identified enhancement of GABAergic neurotransmission as a primary mechanism underlying Selank's anxiolytic properties. Studies in rodent models have found that Selank modulates GABA-A receptor expression and sensitivity, producing anxiolytic effects without the sedation, tolerance, or dependence associated with benzodiazepine-class GABAergic compounds.
BDNF Upregulation
Brain-derived neurotrophic factor (BDNF) is a neurotrophin critical for synaptic plasticity, learning, and memory consolidation. Research has found that Selank administration increases BDNF mRNA expression and protein levels in rodent brain regions involved in learning and memory, particularly the hippocampus — a mechanism believed to underlie its cognitive-enhancing and stress-protective effects in research models.
Anxiolytic Without Sedation
A recurring theme in Selank research is its anxiolytic profile without the sedative, muscle-relaxant, or dependence-forming effects typically seen with benzodiazepine-class compounds. This distinction is one of the primary reasons Selank remains a compound of ongoing interest to researchers studying anxiety biology and stress resilience.
How to Buy Selank in Malaysia
Local vs Overseas Sourcing
Selank research peptide sourced from overseas typically arrives in 3–5 weeks and involves customs risk. As a Malaysia-based supplier, Concept Peptides ships Selank domestically with 1–3 business day delivery and no import complications. Every product is accompanied by a third-party Certificate of Analysis confirming sequence accuracy and purity.
What Format Is It Supplied In?
Concept Peptides supplies Selank as a lyophilised (freeze-dried) powder in sealed research vials, available in a 10mg size. Lyophilisation preserves stability and extends shelf life prior to reconstitution. It is reconstituted with BAC Water prior to use, and a free BAC Water vial is included with every Selank order.
Purity Verification
Every product is independently tested by a third-party laboratory and a Certificate of Analysis (COA) is available upon request, confirming the amino acid sequence, molecular weight, and purity percentage by HPLC.
Frequently Asked Questions
What is Selank used for in research?
Selank is used in preclinical and clinical research settings to study anxiolytic mechanisms, GABAergic neurotransmission, BDNF-mediated neuroplasticity, and stress-related cognitive impairment. Its tuftsin-derived structure also makes it a compound of interest for immunomodulatory research.
Where can I buy Selank in Malaysia?
Research-grade Selank is not sold in pharmacies or retail stores in Malaysia. Concept Peptides is a Malaysia-based supplier stocking Selank in lyophilised research-grade format, with local payment methods and domestic shipping throughout Malaysia — order via WhatsApp or through the product page directly.
Is Selank available in Malaysia?
Yes — Concept Peptides stocks Selank in lyophilised research-grade format, available for order with local payment methods and domestic shipping throughout Malaysia, strictly for research and laboratory use.
How does Selank compare to Semax?
Both Selank and Semax are Russian-developed neuropeptides studied for cognitive research applications, but their primary mechanisms differ. Selank is a tuftsin-derived heptapeptide whose research is centred on GABAergic anxiolytic activity and BDNF-mediated stress resilience. Semax is an ACTH-derived peptide whose research is centred on neuroprotection, BDNF and NGF upregulation, and neuroprotective signalling following ischemic stress. Researchers investigating anxiety and stress biology typically focus on Selank, while those investigating neuroprotection and focus/attention typically focus on Semax. For the full mechanistic overview, see our Semax research article, and for local sourcing details, see our guide on where to buy Semax in Malaysia.
How should it be stored after arrival?
Lyophilised Selank should be stored at -20°C for long-term stability. If the vial will be used within 4–6 weeks, storage at 2–8°C is acceptable. Once reconstituted with BAC water, store the solution at 2–8°C and use within 28 days. Avoid repeated freeze-thaw cycles of the reconstituted preparation.
