SCIENCE
Selank is a heptapeptide analog of the endogenous tetrapeptide tuftsin, developed to produce sustained anxiolytic and cognitive-enhancing actions. By binding to allosteric sites on GABA-A receptors, it modulates chloride ion conductance naturally.
In addition, Selank inhibits enkephalin-degrading enzymes in blood plasma, prolonging the half-life of endogenous opioid peptides that regulate emotional equilibrium, resulting in calmness without cognitive blunting or sedation.
WHAT TO EXPECT
Anxiolytic and stress-moderating effects are noticeable within 15–45 minutes. Emotional balance and memory recall under stress are assessed over 2–3 week periods.
PROTOCOL NOTE
Available in 10 mg sterile vials. For laboratory research only.
FAQ
Selank acts as an allosteric modulator of GABA-A receptors and inhibits enkephalin-degrading enzymes, promoting calmness and focus without sedation, motor impairment, or dependence.
Clinical trials conducted by the Russian Academy of Sciences demonstrate consistent anxiolytic efficacy in generalized anxiety and neurasthenia cohorts with an excellent tolerability profile.
