Neuropeptide for Sleep & Stress Regulation | For Research Use Only

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide known for its role in regulating sleep cycles, reducing stress, and supporting hormonal balance. First discovered in the 1970s, DSIP has been studied for its effects on deep (delta) sleep promotion, cortisol modulation, and neurological recovery. It crosses the blood–brain barrier and is active in the hypothalamus and pituitary.

DSIP is widely researched in models exploring insomnia, anxiety, pain modulation, and HPA axis regulation.

🔍 Key Features

• Promotes Delta Wave Sleep – Enhances slow-wave deep sleep phases

• Reduces Cortisol & Stress Response – Modulates ACTH and supports adrenal regulation

• Neuroprotective Properties – Studied for anti-oxidative and anti-apoptotic effects

• May Aid in Pain & Recovery – Investigated for opioid system interaction and stress-related fatigue

• Supports Hormonal Balance – Shown to influence luteinizing hormone (LH) and growth hormone (GH) release
