DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide first isolated from rabbit brain. In research models it has been studied for its effects on slow-wave sleep EEG patterns, stress hormone modulation, and nociceptive signaling.

DSIP is used in sleep research, circadian studies, and HPA-axis models where modulation of corticotropin and related stress hormones is investigated.
