DSIP (Delta Sleep-Inducing Peptide)
Research-Grade Neuropeptide
Tagline: Sleep, Stress & Neuroendocrine Research
Product Description
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first isolated from the brain that has been linked to the regulation of slow-wave (delta) sleep. It is a nonapeptide with broad effects on the central nervous system, endocrine regulation, and stress adaptation.
Researchers study DSIP to investigate its potential roles in sleep modulation, stress response, pain control, and hormone secretion (LH, GH, ACTH). Its ability to cross the blood-brain barrier makes it an important tool for neurobiology and behavioral research.
For Laboratory and Scientific Research Use Only. Not for Human Consumption.
Why Researchers Choose DSIP
Endogenous Neuropeptide: Provides a physiologically relevant model for sleep research.
CNS Penetrant: Crosses the blood-brain barrier in preclinical models.
Multifunctional: Studied in sleep regulation, hormone modulation, and stress response.
Batch Verified: Identity and purity (≥98%) confirmed for consistency.
Versatile Applications: Used in neurobiology, chronobiology, and psychoneuroendocrine research.

Research Applications
Sleep & Chronobiology Research
DSIP has been shown to promote slow-wave (delta) sleep and normalize circadian rhythms in animal studies [1].
Stress & Cortisol Regulation
Research indicates DSIP may modulate ACTH and cortisol secretion, helping explore hypothalamic-pituitary-adrenal (HPA) axis regulation [2].
Pain Modulation & Analgesia
Preclinical studies suggest DSIP may have analgesic properties, potentially through opioid system modulation [3].
Endocrine Research
DSIP has been associated with LH, GH, and prolactin release, making it useful for pituitary and reproductive research [4].

Mechanism of Action (How DSIP Works)
CNS Penetration: Crosses the blood-brain barrier, exerting central effects on sleep regulation [Graf 1981].
Hypothalamic Interaction: Modulates hypothalamic nuclei involved in sleep and hormone release [Przewlocki 1983].
Neuroendocrine Modulation: Influences pituitary release of GH, LH, and ACTH [Kastin 1990].
Opioid System Involvement: May interact with opioid peptides, explaining analgesic effects [Sudakov 1987].
Circadian Rhythm Regulation: Normalizes sleep-wake cycles in animal models [Graf 1981].
