What Is Selank?

Selank is a synthetic nootropic peptide developed in Russia for anxiolytic, cognitive-enhancing, and immune-modulating research interest. It is derived from human tuftsin, a naturally occurring peptide involved in immune regulation, and has been studied in models related to anxiety disorders, cognitive decline, and stress-related conditions.

Mechanisms of Action

  • Anxiolytic effects through modulation of serotonin receptor activity, supporting calmness, emotional stability, and stress resilience without the sedative profile seen with traditional anxiolytics.

  • Cognitive enhancement through increased brain-derived neurotrophic factor (BDNF) signaling, supporting neuroplasticity, learning, memory retention, and mental clarity.

  • Immune modulation through regulation of cytokine activity, which may contribute to overall stress resistance and mood stability in research models.

Benefits

  • Stress and anxiety reduction signals that may mitigate chronic stress, anxiety, and depression related endpoints, including in high-stress lifestyle and generalized anxiety disorder (GAD) research frameworks.

  • Cognitive enhancement signals that may improve focus, mental clarity, and learning ability in performance and productivity oriented paradigms.

  • Mood stabilization and emotional resilience signals that may help regulate emotional responses in research contexts relevant to PTSD, ADHD, and other neuropsychiatric conditions.

Dosing

Strength

Dose

Low

100-200 mcg daily

Medium

250-300 mcg daily

High

400-500 mcg daily

Administration routes: intranasal spray or subcutaneous injection.

Nasal administration note: dosing is often divided across the day.

Duration note: commonly used for 2 to 4 weeks to assess effects, with some protocols extending based on response.

Safety Profile

Selank is generally described as well tolerated, with minimal reported side effects.

  • Intranasal use may cause mild nasal irritation.

  • Mild drowsiness can occur in sensitive individuals.

  • Rare headaches may occur and are typically described as resolving with continued use.

Unlike benzodiazepines or sedatives, Selank is described as not causing dependence, withdrawal, or cognitive impairment in these discussions.
