DSIP Peptide

10mg · Lyophilized Powder · ≥98%

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from rabbit brain tissue in 1977. Research has examined its effects on sleep architecture, particularly delta wave (slow-wave) sleep patterns, as well as interactions with the hypothalamic-pituitary-adrenal axis and stress hormone modulation.

DSIP Published Research

Delta sleep-inducing peptide (DSIP) is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from rabbit brain in 1977. Research has investigated its effects on sleep architecture, stress response markers, and endocrine regulation in animal and human studies.

Sleep Architecture Research

Published research has examined DSIP's effects on sleep stage distribution in EEG-monitored animal models. Studies investigated its effects on delta wave (slow-wave) sleep patterns and circadian rhythm markers. Research characterized its distribution in hypothalamic and limbic brain regions involved in sleep regulation.

Stress and Endocrine Research

Studies have investigated DSIP's effects on stress-related endocrine markers, including cortisol, ACTH, and growth hormone profiles. Published research examined its effects in acute and chronic stress models in animals. Additional studies investigated DSIP in the context of opioid peptide interactions.
