How DSIP Works
DSIP is a naturally occurring neuropeptide found in the brain. Research suggests it modulates sleep architecture, particularly delta (slow-wave) sleep. Studies indicate it may interact with the hypothalamic-pituitary-adrenal axis and influence stress hormone release, circadian rhythms, and sleep-wake cycles.
