Selank
Strongest for cognitive enhancement
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.

How Selank 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.
