Selank (10 mg) is a synthetic heptapeptide research compound based on tuftsin, studied for anxiolytic, nootropic, and immunomodulatory pathways. Third-party tested at 99% purity with a batch-specific COA. Ships across Canada. For research use only — not for human consumption.
Selank is a synthetic heptapeptide research compound studied in laboratory settings for its role in neuropeptide and anxiolytic signaling research. Based on the naturally occurring immunopeptide tuftsin, Selank is examined for its interaction with stress-related and neurological research models. Each vial from Central Peptides contains 10 mg of high-purity Selank, third-party verified and supplied with a batch-specific Certificate of Analysis (COA) for research use only. As one of the most studied nootropic research peptides, Selank remains a frequently requested compound among Canadian laboratories.
Selank Research Applications
Selank is a synthetic analog of the tetrapeptide tuftsin (Thr-Lys-Pro-Arg), extended at the C-terminus with a Pro-Gly-Pro motif that resists enzymatic breakdown. This structural engineering gives Selank greater stability in solution compared to the parent tuftsin fragment, which is rapidly degraded by peptidases. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, Selank is studied for its triple research profile spanning anxiolytic, nootropic, and immunomodulatory pathways.
In controlled laboratory environments, researchers explore Selank for how the Pro-Gly-Pro stabilizing tail affects peptide persistence and blood-brain-barrier permeability. It is frequently studied alongside its sister peptide Semax, with which it shares the same C-terminal Pro-Gly-Pro engineering element.
Common research areas where Selank is examined include:
Anxiolytic and stress-response signaling models
Neuropeptide and nootropic research pathways
Immunomodulation and cytokine expression studies
Comparative research with tuftsin and related peptides
Purity and Quality Verification
Every batch of Selank sold by Central Peptides is manufactured under controlled synthesis and purification processes to ensure stability, consistency, and structural integrity for scientific research applications. Our compounds are independently tested and verified at 99% purity through High-Performance Liquid Chromatography (HPLC) and mass spectrometry.
Each order includes access to a batch-specific Certificate of Analysis, allowing researchers to verify identity, purity percentage, and testing details before use. This batch-level traceability is part of our commitment to transparency and quality control across our full research catalog. Researchers who require documented purity standards for their work can review the COA before and after purchase, ensuring every vial meets the same verified specification.
Selank is supplied as a lyophilized (freeze-dried) powder for maximum stability during shipping and storage. Lyophilization removes moisture from the compound, which helps preserve its structural integrity over time and allows it to remain stable during transit. For long-term integrity, store the lyophilized compound in a cool, dry environment away from light.
Once reconstituted for research, Selank is readily soluble in water and should be kept refrigerated at 2-8°C. To preserve compound integrity, aliquot the reconstituted material to avoid repeated freeze-thaw cycles, and use within an appropriate window to maintain consistency in research results.
Shipping Across Canada
Central Peptides ships Selank and all research compounds across Canada in discreet, temperature-conscious packaging. Orders are typically processed within 24 hours and delivered within 3 to 5 business days. Free delivery is available on qualifying orders over the threshold listed at checkout.
As a Canadian-based supplier, we offer domestic fulfillment, which means faster delivery times and fewer customs complications compared to ordering from international sources. Every shipment is packaged to protect the compound during transit and to maintain privacy.
