What ships with your order
Selank is a synthetic heptapeptide analogue of the immunomodulatory peptide tuftsin, developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. Research has documented anxiolytic-like activity via GABAergic and enkephalin pathways, BDNF upregulation, and immune modulation — without the sedation or dependency profile of benzodiazepines in animal models. ≥98% HPLC, third-party CoA.
Selank is a synthetic heptapeptide analogue of the immunomodulatory peptide tuftsin, developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. Research has documented anxiolytic-like activity via GABAergic and enkephalin pathways, BDNF upregulation and immune modulation without the sedation profile of benzodiazepines in animal models. Peptides UK supplies Selank 10mg as ≥98% HPLC lyophilised powder with a signed third-party Certificate of Analysis.
Selank is the synthetic sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro — the tetrapeptide immunomodulator tuftsin with a stabilising Pro-Gly-Pro C-terminal extension. It was developed as a metabolically stable research tool for the anxiolytic and neuromodulatory pathways originally observed with tuftsin in in-vitro immunology and neuroscience research.
Selank has been documented to modulate GABA-A receptor signalling in ways that produce anxiolytic-like effects in animal models without inducing sedation, tolerance or physical dependence characteristic of benzodiazepines. Additional research has shown upregulation of BDNF and enkephalin expression, modulation of inflammatory cytokines, and interactions with the serotonergic and dopaminergic systems. These properties make Selank a reference compound for non-benzodiazepine anxiolytic pathway research.
Published research has investigated Selank in anxiolytic-pathway modelling, GABAergic signalling studies, BDNF and neurotrophic factor research, stress-response and HPA-axis modulation, immunomodulation, and comparative pharmacology against benzodiazepines and other anxiolytic reference compounds. The 10mg vial supports extended research protocols at standard reconstitution concentrations.
Store the lyophilised vial at -20°C, sealed and protected from light. Reconstitute with bacteriostatic water (0.9% benzyl alcohol) — typically 1–2ml per 10mg vial. Add solvent slowly down the inside wall of the vial. Refrigerate the reconstituted solution at 2–8°C and use within 28 days. Do not refreeze.
Every Selank 10mg lot is independently HPLC-UV tested to ≥98% purity by Janoshik Analytical or Aspen Bioanalytics, with mass-spectrometry identity confirmation against the published molecular weight of 751.88 Da. The signed PDF CoA is supplied with every order and matches the vial lot number.
Selank sits alongside Semax as one of the most-counterfeited nootropic research peptides on the grey market. Peptides UK addresses this with mandatory third-party verification, UK-stocked inventory, same-day Manchester dispatch and full lot traceability from the vial sticker to the CoA on this page.
