What is DSIP?

DSIP, or Delta Sleep-Inducing Peptide, is a well-known neuropeptide consisting of nine amino acids with the sequence: Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu.⁷

First isolated from the cerebral venous blood of rabbits in a state of deep (delta) sleep, this peptide is naturally found in the hypothalamus, pituitary gland, and other brain and peripheral tissues.⁸ It is notable for its ability to cross the blood-brain barrier, allowing it to exert central effects.⁹

Mechanism and Research Interest

DSIP is a subject of significant scientific interest due to its diverse physiological activities.¹⁰

• Sleep Regulation: Its primary area of study, as implied by its name, is its role in sleep architecture. Research suggests it may help induce and enhance slow-wave sleep (SWS), the deepest and most restorative stage of sleep, without altering natural sleep patterns.¹¹

• Stress Modulation: DSIP is often described as a “stress-protective” peptide.¹² Studies explore its potential to modulate the hypothalamic-pituitary-adrenal (HPA) axis, the body’s main stress response system, which may help normalize cortisol levels and improve physiological adaptation to stress.¹³

• Endocrine Function: Research has also indicated that DSIP may influence the release of other hormones, including luteinizing hormone (LH) and growth hormone (GH), and may have a regulatory effect on the endocrine system.¹⁴
