DSIP (Delta Sleep-Inducing Peptide) at a glance
DSIP is a 9-amino-acid peptide first isolated from rabbit cerebral venous blood. Studied for sleep regulation, stress modulation, and circadian rhythm support. Mechanism: Sleep-modulating nonapeptide. Typical route: Subcutaneous or intranasal. FDA status: Not FDA-approved. Available through compounding pharmacies and research-chemical suppliers; quality control varies substantially.
Drug classSleep-modulating nonapeptide
Half-life~7 minutes (parenteral)
RouteSubcutaneous or intranasal
Common dosing100-500 mcg before bed
FDA statusNot approved
Available throughCompounding pharmacies
Mechanism of action
DSIP appears to modulate the hypothalamic-pituitary-adrenal (HPA) axis, reduce stress-induced cortisol elevation, and shift sleep architecture toward more delta (deep) sleep phases. Mechanism is incompletely understood; the peptide's named function (sleep induction) is supported more in animal models than in robust human trials.
Dosing reference
Subcutaneous or intranasal: 100-500 mcg taken 30-60 minutes before bedtime. Many protocols cycle 5-7 days on, then 2-3 days off, given the unclear long-term safety profile.

Frequently asked questions about DSIP (Delta Sleep-Inducing Peptide)
Does DSIP actually improve sleep?
Evidence is mixed. Animal studies and small open-label human trials show modulation of sleep architecture, but well-controlled trials are limited. Some users report subjective sleep improvement; others see no effect.
Is DSIP addictive?
DSIP does not act on GABA-A receptors and is not associated with the dependence patterns seen with benzodiazepines or Z-drugs. Long-term safety data is limited.
