Selank (5mg)

Selank

Supplied as a lyophilized (freeze-dried) white powder in a sealed sterile vial. Requires reconstitution with bacteriostatic water prior to use. Each vial contains 5mg of Selank at ≥99% purity.

Selank is a synthetic heptapeptide based on tuftsin (Thr-Lys-Pro-Arg) with an added Pro-Gly-Pro (PGP) sequence at the C-terminus for enhanced stability and resistance to enzymatic degradation. Tuftsin is a naturally occurring tetrapeptide derived from the Fc region of immunoglobulin G with documented immunomodulatory properties. It has been extensively researched and is known to modulate GABAergic and serotonergic neurotransmission, support anxiolytic activity without sedative effects, regulate stress response and mood, promote cognitive function and memory, and balance immune function through cytokine and inflammatory pathway modulation.

Research Background

Research has examined Selank's effects on GABAergic neurotransmission, including its interaction with GABA-A receptors and effects on GABA metabolism. Studies have investigated its anxiolytic profile, comparing its mechanisms with classical benzodiazepines and other anxiolytic compounds — noting its ability to produce anxiolytic effects without the sedative or dependency-related side effects associated with traditional compounds. Additional research has explored Selank's immunomodulatory effects, including its influence on cytokine expression, immune cell function, and inflammatory responses. Its dual activity across both neurological and immune systems makes it a particularly valuable research tool for studying neuroimmune interactions.
