About this compound
DSIP stands for delta sleep-inducing peptide. It is nine amino acids long and was first isolated in 1977 from blood drawn during deep sleep. Studies have measured brain wave patterns, sleep timing, and stress hormone response. After nearly fifty years of research, no one has identified which receptor it binds. The mechanism is still an open question.

How It Works
How DSIP works
The pathways DSIP acts on — and what each one does. The animation traces its signal outward from the compound to every target it engages.
Signalling pathways studied in preclinical models · illustrative
Neurotransmitter Modulation
Neuromodulator
DSIP has been reported to influence serotonin (5-HT), glutamate, dopamine and melatonin signaling — pathways tied to sleep onset and circadian timing.
Sleep Architecture
Delta Sleep ↑
Early studies associate DSIP with greater slow-wave (delta) sleep, shorter sleep onset and higher sleep efficiency, distinct from sedative-hypnotic mechanisms.
Stress & Neuroprotection
Neuroprotective
Investigated for adaptation of the stress (HPA) axis and for neuronal oxidative-stress endpoints in neurodegeneration and stroke models.

FAQ
Common questions about DSIP
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated in the 1970s from the cerebral venous blood of rabbits in an induced sleep state, studied as an endogenous modulator of sleep and stress.
Yes. DSIP is an endogenous neuropeptide found in the brain, hypothalamus and other tissues, which is part of why it is of interest as a physiological sleep regulator.
Primarily sleep regulation, but also stress adaptation, neuroprotection, chronic-pain models and studies of opioid/alcohol withdrawal.
