DSIP
Delta Sleep-Inducing Peptide
A neuropeptide that promotes delta-wave sleep and has stress-modulating properties. Used for sleep disorders, stress reduction, and hormonal normalization.
Mechanism of Action
DSIP modulates delta-wave (slow-wave) sleep by interacting with sleep-regulating centers in the hypothalamus. It reduces ACTH and cortisol levels, normalizes LH and GH pulsatility, and exhibits antioxidant properties.
Health Claims & Evidence
Promotes deep delta-wave sleep
Reduces stress and cortisol levels
Normalizes hormonal rhythms
Short-Term Effects
Improved sleep onset and depth, reduced nighttime cortisol, enhanced morning recovery.
Long-Term Effects
Potential normalization of sleep architecture and hormonal rhythms with cycling.
Side Effects
Generally well-tolerated. Mild drowsiness. Rare reports of nausea.
Contraindications
Limited data. Use with caution alongside other sleep aids.
