DSIP
PH-DSIP-001
Specifications
Description
DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide studied for its effects on sleep physiology, circadian rhythm, and stress response. Originally isolated from rabbit brain, it modulates sleep architecture.
Mechanism of Action
DSIP acts on multiple neuroendocrine pathways involved in sleep regulation and stress response (Kovalzon et al., 2006). Research shows effects on delta wave sleep induction and cortisol modulation (Graf & Kastin, 1984).
Research Applications
- Sleep physiology research (Kovalzon et al., 2006)
