DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide found in the brain. Research demonstrates promotion of delta-wave (deep) sleep, stress modulation, normalization of disturbed sleep patterns, and modulation of corticotropin and cortisol levels. It acts through GABAergic and serotonergic mechanisms to promote physiological sleep architecture.
