Selank
A synthetic heptapeptide analogue of tuftsin, studied in anxiety-reduction and cognitive research.
Selank (TP-7) is a synthetic neuroregulatory and immunomodulatory peptide derived from the body's own immune peptide tuftsin (Thr-Lys-Pro-Arg). It consists of seven amino acids in a specific sequence: threonine-lysine-proline-arginine-proline-glycine-proline (Thr-Lys-Pro-Arg-Pro-Gly-Pro / TKPRPGP). The natural tuftsin sequence was extended with a proline-glycine-proline triplet at the C-terminus to improve structural stability and resistance to peptidases in plasma and mucosal tissue, multiplying its biological half-life and its ability to reach the central nervous system rapidly. Selank works through a multi-target, non-sedating signalling system: it exerts positive allosteric modulation on gamma-aminobutyric acid type A receptors (GABA-A), enhancing inhibitory neurotransmission and damping excess excitation in the cortex and limbic system without binding the classic benzodiazepine site. This gives it an anxiolytic effect entirely free of sedation, drowsiness, tolerance or dependence. It also influences monoamine metabolism — regulating serotonin, noradrenaline and dopamine — and strongly stimulates gene expression and production of brain-derived neurotrophic factor (BDNF) in the hippocampus, enhancing synaptic plasticity, working memory and learning. On the immune side, it modulates inflammatory cytokines such as interleukin-6 (IL-6) and regulates mononuclear interferon responses, providing a comprehensive biological shield linking the nervous and immune systems.
The innate neuroregulator for calming anxiety and stress, sharpening focus and memory and raising BDNF — without sedation or dependence
If you want to get rid of anxiety episodes and daily psychological pressure, clear distraction and brain fog, and support memory and learning by raising neurotrophic factors — without the drowsiness, lethargy and slowed reactions of traditional sedatives — Selank is the most balanced smart compound, combining calm with sharp mental alertness.
Classification: GABA-modulating neuropeptides, cognitive enhancers and BDNF inducers, non-sedating anxiolytics and immune modulators (Anxiolytic Nootropic Peptides / Allosteric GABA-A Modulators / Neuro-Immune Regulators).
Structurally, it is a pure heptapeptide that combines the functional core of the immune peptide tuftsin with a protective proline tail. This precise engineering gives it exceptional physiological stability and the ability to reach the brain's processing centres immediately without losing its biological activity.
Picture your mind under constant stress as a noisy engine room with gears spinning at crazy speeds, causing distraction and overheated thinking. Ordinary sedatives are like cutting the power entirely — stopping production and forcing the body into sleep — whereas Selank acts as an expert engineer who oils the gears and fine-tunes the engine speed, so the machines run at full capacity calmly and smoothly.
How it works
Selank spreads through the central nervous system and binds specific modulatory sites on GABA-A receptors, strengthening the flow of innate relaxation signals and quieting panic, phobia and chronic anxiety, while fully preserving clear attention and focus without sedation. At the same time, the peptide acts in the hippocampus and prefrontal cortex to stimulate BDNF release and repair synapses, improving storage and recall of information, speeding learning and stabilising mood by balancing key neurotransmitters such as serotonin and dopamine. Alongside its neural activity, Selank has a protective immune function — lowering the inflammatory cytokines that cause fatigue and regulating the body's response to oxidative stress — giving the brain and body an integrated environment of calm, strong cognition and robust neuro-immunity.
In advanced clinical and research settings, Selank was developed and used at molecular-genetics centres as an official treatment for generalised anxiety disorder, neurasthenia and cognitive disturbances accompanying acute psychological stress, and it is widely studied in neurology and regenerative medicine as a superior biological alternative to classic anxiolytics.
Peace of mind and mental excellence do not require sedatives that cloud awareness — they rest on awakening the innate language of neural regulation that gives your mind calm and intelligence at the same time.
The smart neural compound for calming anxiety, sharpening memory and stimulating brain growth factors — without any sluggishness. Selank is an advanced Russian achievement in nootropic neuropeptide research inspired by the body's own chemistry. It belongs to the class of non-sedating anxiolytics and BDNF enhancers that support focus, emotional stability and resistance to neural stress. Its highly stable seven-amino-acid structure binds GABA receptors in the brain intelligently, acting as a physiological regulator that quiets stress, fear and mental pressure without drowsiness, dullness or dependence. Its unique mechanism raises neurotrophic factors in the hippocampus, repairs synaptic connections and balances serotonin and dopamine, clearing distraction and fog and giving you sharp memory and fast comprehension, while strengthening cellular immunity against exhaustion. Leading neuropsychiatry researchers study it as an advanced natural alternative combining complete clarity of thought with deep calm — because true mental strength begins by establishing calm within your nervous system with a pure biological code that protects your mind and releases its innate abilities.
