Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide first isolated in 1977 from sleeping rabbits. It acts through multiple central nervous system pathways, influencing sleep architecture, stress response, and neuroendocrine signaling.
Research has characterized DSIP for effects on delta-wave sleep duration, cortisol normalization, GH secretion, and reduction of withdrawal symptoms in substance-dependence models.
