Selank is a synthetic heptapeptide developed by the Institute of Molecular Genetics, Russian Academy of Sciences, as an improved analog of the immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg). The addition of Pro-Gly-Pro at the C-terminus dramatically increases metabolic stability and brain penetration. Approved in Russia since 2009 as a nasal spray for generalized anxiety disorder (GAD) and adjustment disorders, it is one of the few peptides with proven clinical anxiolytic efficacy comparable to benzodiazepines — but without sedation, cognitive impairment, or dependence. This research-grade lyophilized powder is synthesized under strict quality controls and provided with full analytical documentation, making it the gold-standard for anxiolytic, nootropic, and neuroimmune research.
Key Scientific Features
- High-purity Selank (≥ 99% by HPLC/MS, acetate salt form)
- Verified heptapeptide sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP)
- Lyophilized formulation for maximum long-term stability
- Full Certificate of Analysis (COA) with HPLC, MS, and amino acid analysis
- Manufactured in GMP-aligned, ISO-compliant facilities
- Ideal for anxiolytic, BDNF/enkephalin modulation, and intranasal delivery studies
Research-Referenced Attributes (Based on scientific literature; not intended as therapeutic claims.)
- Rapid anxiolytic effect (within 1–3 min intranasally) via allosteric modulation of GABA-A receptors and enkephalin preservation
- Increases BDNF expression in hippocampus — enhances learning, memory, and neuroplasticity
- Normalizes serotonin metabolism and reduces stress-induced immune suppression
- Clinically proven in Russia: 70–80% response rate in GAD with no sedation or withdrawal (n>500 patients)
- Improves cognitive function in stress/anxiety models without habituation
- High nasal bioavailability (>90%) and excellent safety profile — no benzodiazepine-like side effects
