What is Selank?
Selank is a synthetic peptide derived from the naturally occurring tetrapeptide tuftsin, designed to reduce anxiety, modulate the immune system, and enhance cognitive performance—all without the addictive potential or sedative effects of traditional anti-anxiety drugs like benzodiazepines.
Developed by the Russian Academy of Sciences in the 1990s, Selank is classified as a nootropic, anxiolytic, and immunomodulator. It has been approved in Russia for treating Generalized Anxiety Disorder (GAD) and is now being explored by biohackers and peptide researchers worldwide for a broader array of applications.
Key Benefits of Selank
Reduces Anxiety: Mimics the calming effects of benzodiazepines by enhancing GABA signaling—without the risk of dependency.
Enhances Cognitive Function: Improves memory, focus, and mental clarity.
Boosts Mood: Modulates serotonin and dopamine levels, reducing depressive symptoms.
Supports Immune Health: Reduces inflammation by balancing cytokine expression, particularly IL-6.
Adaptogenic: Helps the body respond better to chronic stress by reducing cortisol levels.
Antiviral: Inhibits influenza virus replication better than IFN-α in some studies.
Mechanism of Action
Selank doesn’t just suppress symptoms—it works at the root level of brain and immune function. Here's how:
GABAergic Modulation: Increases the affinity of GABA receptors to reduce excitability in the CNS.
Enkephalin Protection: Prevents breakdown of natural peptides that reduce anxiety and pain.
Neurotransmitter Regulation: Balances levels of serotonin and dopamine, leading to mood stabilization.
Immunomodulation: Reduces pro-inflammatory cytokines, such as IL-6, commonly elevated in depression and chronic stress.
Studies in rodents and humans have shown Selank alters gene expression of over 45 neurotransmission-related genes within 1 hour of administration. This leads to rapid effects with minimal systemic side effects.
Selank Dosage and Protocol
Route: Subcutaneous injection (most stable and effective)
Dosage:
150–300 mcg per day
Duration: 10–14 days
Cycle: Optional week off after each cycle
For best results, administer once daily into adipose tissue (e.g., abdominal fat) using a small insulin syringe. Onset may take several days, with effects becoming more pronounced after the first week.
Note: Some research users alternate with another peptide like Semax for synergistic cognitive and neuroprotective effects.
Side Effects and Safety
Selank is generally well-tolerated. No serious side effects have been reported in human trials or animal studies.
Reported minor effects:
Headache
Injection site irritation
Nausea (rare)
Compared to benzos, Selank has no sedative effects, no withdrawal, and no cognitive blunting. In fact, it appears to enhance cognition even during long-term use.
Top Use Cases for Selank
