Research details
Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic heptapeptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It is a modified analog of the naturally occurring immunopeptide tuftsin (Thr-Lys-Pro-Arg), extended with a Pro-Gly-Pro C-terminal tripeptide that dramatically enhances its metabolic stability and bioavailability. Selank exhibits a unique triple pharmacological profile, anxiolytic, nootropic and immunomodulatory, without producing sedation, tolerance, or physical dependence, distinguishing it fundamentally from classical benzodiazepines. It modulates GABAergic, serotonergic (5-HT), and dopaminergic neurotransmission, making it one of the most versatile research neuropeptides available.
At Bergdorf Bioscience, Selank is supplied as a high-purity, lyophilized (freeze-dried) powder. This manufacturing process removes moisture from the peptide, ensuring maximum chemical stability and a long shelf life even at ambient temperatures.
When you buy Selank for your research laboratory, you need absolute reliability and consistent quality. Selank is available at Bergdorf Bioscience as 10 mg lyophilized vials in convenient multi-pack options:
Every vial is filled under strict laboratory conditions and individually sealed. All batches are analyzed by High-Performance Liquid Chromatography (HPLC) and carry a guaranteed purity of ≥99%. Our quality assurance also includes mass spectrometry (MS) for molecular weight confirmation and rigorous endotoxin testing to ensure research-grade safety.
We ship all our research peptides worldwide from within the EU, as an ordinary tracked parcel in discreet packaging. Thanks to professional lyophilization, Selank powder is highly temperature-stable in its unmixed state. The molecular integrity and biological activity of the peptide are fully preserved at normal ambient temperatures throughout transit. After reconstitution (dissolving in bacteriostatic water), we recommend storing the vial in a refrigerator.
Modulates GABA-A receptor allosterically; influences BDNF and NGF expression; enhances enkephalin stability.
Advanced protocol
250-500 mcg, 1-3x daily; intranasal route in published studies
Note: The dosages listed correspond to typical ranges from published research literature. They do not replace advice from a qualified researcher or physician.
Every batch is analyzed by an independent laboratory via HPLC before shipment. We document purity (avg. 99.43% in 2026), mass spectrometry identity, and sterility. Production follows GMP standards in ISO-certified laboratories.
Selank is a synthetic heptapeptide and modified tuftsin analog with a Pro-Gly-Pro extension. Developed by the Russian Academy of Sciences, it modulates GABA, serotonin, and dopamine, acting as an anxiolytic without sedation or dependence potential.
