Selank is a synthetic heptapeptide derived from tuftsin, developed for research into its potential effects on mood regulation and cognitive performance. It is widely studied for its anxiolytic (anti-anxiety) properties and its ability to promote a sense of calm without causing sedation. Research suggests that Selank may help modulate key neurotransmitters such as serotonin and dopamine, supporting emotional balance and mental clarity. It has also been explored for potential nootropic benefits, including improved focus, memory, and learning capacity. Additionally, Selank may play a role in supporting immune response through cytokine regulation, making it a compound of interest in various scientific studies.
