Overview

DSIP (Delta Sleep-inducing Peptide) is a naturally occurring neuropeptide that was first isolated from the brain in 1977. It plays a role in regulating sleep-wake cycles, particularly in promoting delta wave sleep (deep sleep). DSIP appears to work through multiple mechanisms, affecting GABA, serotonin, and other neurotransmitter systems.

Unlike traditional sleep medications, DSIP promotes natural sleep architecture without dependency or tolerance. It may also have additional benefits including stress reduction, improved immune function, and hormonal regulation.
