P21 is a synthetic tetrapeptide derived from Cerebrolysin, designed to mimic the neurotrophic effects of ciliary neurotrophic factor (CNTF). The peptide promotes neurogenesis in the hippocampus and enhances synaptic plasticity, making it a promising compound for cognitive enhancement research. P21 crosses the blood-brain barrier and increases BDNF levels in the brain, stimulating the formation of new neurons and synaptic connections. Unlike larger neurotrophin proteins that cannot penetrate the CNS effectively, P21 small molecular size allows for systemic administration while maintaining neurogenic activity.
