DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first identified in the 1970s for its role in promoting slow-wave (deep) sleep. It consists of a short chain of amino acids that may act on the hypothalamus and pituitary gland, thereby influencing how the body manages sleep, recovery, and hormonal stress responses.
