Category 2Nasal spray · Injection

Selank is a synthetic version of a natural immune-regulating peptide, developed by the Russian Academy of Sciences. This anti-anxiety and cognitive-enhancing peptide has been extensively studied for its ability to reduce anxiety, enhance cognitive function, and modulate immune responses without the side effects associated with traditional benzodiazepines. Selank works through GABA, serotonin, and dopamine systems, offering a unique combination of calm focus and immune support that sets it apart from conventional anti-anxiety medications.

How it works

Selank calms the nervous system by enhancing GABA activity, your brain's natural "slow down" signal, which reduces anxiety without sedation. It also balances serotonin and dopamine levels, improving mood and sharpening focus. On top of that, it boosts BDNF (a protein that supports learning and memory) in the hippocampus and helps regulate inflammatory signaling, which is why it also supports immune function.

Key benefits

  • Fast-acting anti-anxiety effects
  • Boosts BDNF, a key protein for learning and memory
  • Improves resilience to stress
  • Sharpens focus and cognitive function
  • Supports immune system balance
  • No tolerance or withdrawal reported
  • Protects brain cells from damage

Nasal spray

recommended

Nasal Selank activates NMDA receptor binding sites that injection does not, making it genuinely stronger for cognitive enhancement and brain function. Direct nose-to-brain transport via olfactory pathways provides rapid onset in 15-30 minutes. Best for on-demand cognitive support and fast-acting anxiety relief.
