DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide that was initially isolated from rabbit brain based on its ability to induce delta-wave sleep (deep, slow-wave sleep) when injected into recipient animals. While its precise mechanism remains incompletely understood, DSIP has been shown to modulate sleep architecture, stress responses, and circadian rhythms. The peptide has been researched for insomnia, narcolepsy, chronic pain, and stress-related disorders. DSIP may work through multiple pathways including modulation of GABA and glutamate neurotransmission. Despite decades of research, DSIP remains primarily a research compound without approved clinical applications.
