Research use only DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first isolated from the brain and plasma. It is a nonapeptide associated with the regulation of sleep-wake cycles and neuroendocrine function. Research indicates DSIP may promote slow-wave sleep, modulate pituitary hormone secretion, and exhibit stress-protective and antioxidant properties. Preclinical studies also suggest potential roles in pain modulation, immune regulation, and neuroprotection, making it a versatile compound in the field of neurobiology research
