Overview
DSIP, or Delta Sleep-Inducing Peptide, is a small peptide studied for sleep regulation, stress response, and neuroendocrine balance. It is commonly discussed as a sleep peptide because of its potential relationship to relaxation, recovery, and sleep quality. DSIP may influence systems involved in stress hormones, circadian rhythm, and nervous system regulation. Its purpose is usually connected to deeper rest, improved recovery, and nervous system support. Although the research is mixed and its exact role in human sleep is not fully understood, DSIP remains a well-known peptide in the sleep, recovery, and mind-support category.
