How DSIP Works

DSIP is a nonapeptide originally isolated from rabbit cerebral venous blood during electrically induced sleep. It promotes delta-wave (slow-wave) sleep by modulating neuroendocrine signaling, although its exact receptor has not been definitively identified. DSIP modulates corticotropin and cortisol levels, influences the hypothalamic-pituitary-adrenal axis, has analgesic properties through opioid system modulation, and exhibits antioxidant effects. It normalizes disrupted sleep architecture and has stress-protective effects on multiple organ systems.
