DSIP
Delta sleep-inducing peptide for deep rest
Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide that promotes delta-wave sleep — the deepest and most restorative phase. It also modulates stress hormones and pain perception.
⚙️ Mechanism of Action
DSIP modulates the hypothalamic-pituitary-adrenal axis, reduces cortisol, and promotes the release of LH. It enhances delta-wave EEG activity during sleep onset and may interact with opioid and serotonin pathways.
✅ Benefits
- •Promotes deep, restorative delta-wave sleep
- •Reduces stress hormone (cortisol) levels
- •Analgesic (pain-reducing) effects
- •May improve LH and hormone balance
⚠️ Risks & Considerations
- •Very limited clinical trial data
- •Rapid degradation in blood (short half-life)
- •Inconsistent results in studies
- •Quality concerns with peptide sourcing
