Product Description

Delta-Sleep Inducing Peptide (DSIP) is an endogenous linear nonapeptide derived from mammalian cerebrospinal fluid. As a central neuromodulatory peptide with favorable water solubility and metabolic stability, it has lower receptor tolerance risk than melatonin, for preclinical research on sleep and neuroendocrine regulation.

In vitro tests reveal that DSIP regulates GABA and serotonin pathways to inhibit excitatory neurotransmitter secretion, trigger delta slow-wave generation, shorten sleep latency and improve deep sleep quality. It also protects neurons via eliminating intracellular reactive oxygen species.

In vivo studies prove that DSIP crosses the blood-brain barrier to reduce stress-induced corticosterone release, relieving stress-related sleep disorders. It also has mild anti-fatigue and immunomodulatory effects. This product is only for laboratory research.
