DSIP Extended
Delta Sleep-Inducing Peptide Extended Protocol
Delta sleep-inducing peptide (DSIP) is a nonapeptide that promotes slow-wave (delta) sleep, reduces stress-induced cortisol release, and has demonstrated analgesic and anti-oxidant properties. Extended protocols explore its role in sleep architecture optimization.
Mechanism of Action
DSIP modulates GABA-A and NMDA receptor activity, promoting delta wave sleep. It inhibits somatostatin release, modulates the HPA axis to reduce cortisol, and has antioxidant properties through free radical scavenging. It may also modulate circadian rhythm entrainment.
Health Claims & Evidence
Increases slow-wave (delta) sleep duration
Reduces stress-induced cortisol elevation
Analgesic properties in chronic pain models
Short-Term Effects
Improved sleep onset and depth within 1–3 days of use.
Long-Term Effects
Improved sleep architecture and stress resilience with cycled use.
Side Effects
Generally well-tolerated. Rare reports of vivid dreams, mild headache.
Contraindications
Insufficient human safety data for long-term use. Not recommended during pregnancy.
