Overview
Selank is a synthetic peptide commonly associated with anxiety support, stress reduction, mood balance, and cognitive function. It is related to tuftsin, a naturally occurring immune-signaling peptide, and is often used intranasally in regions where it is available. Selank is usually described as a nootropic peptide or calming peptide because it may support mental clarity without acting like a traditional stimulant. Its purpose is to promote a calmer stress response, emotional balance, and focused mental performance. As a mind peptide, Selank is best known for anxiety-related research, mood support, and cognitive wellness.
