DSIP (Delta Sleep-Inducing Peptide)

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide first isolated from rabbit cerebral venous blood by Monnier et al. in 1977. It has since become one of the most studied peptides in sleep biology, neuroendocrine regulation, and stress-response research.

Mechanism of Research Interest
DSIP is studied for its interaction with the hypothalamic-pituitary-adrenal (HPA) axis, where research has explored its role in modulating cortisol secretion, ACTH release, and the broader stress-response cascade. Its ability to cross the blood-brain barrier makes it a particularly significant subject in central nervous system peptide research.

Sleep Architecture Research
Studies have explored DSIP's role in delta wave sleep promotion and circadian rhythm regulation. Research suggests it may influence the balance between REM and non-REM sleep phases, making it a key compound in sleep quality and circadian biology research models.

Neuroprotective Properties
Emerging research has explored DSIP's potential neuroprotective effects, including its role in reducing oxidative stress markers in neuronal tissue and its interaction with somatostatin and LH-RH pathways in neuroendocrine research.

Stress Response Modulation
DSIP has been studied for its ability to attenuate stress-induced physiological responses in preclinical models, with research exploring its role in HPA axis normalisation and stress hormone regulation.

Each vial contains 10mg of lyophilized DSIP with ≥99% purity, verified by third-party HPLC testing.
