DSIP Research Guide

Full name: Delta Sleep-Inducing Peptide

A nonapeptide discovered in 1977 that modulates sleep architecture by promoting delta wave (deep sleep) patterns and normalizing circadian disruptions.

How DSIP Works

Modulates GABAergic and glutamatergic neurotransmission in sleep nuclei. Enhances delta wave NREM sleep, normalizes circadian patterns, and reduces cortisol/CRH during sleep.

Dosing Protocol

• Typical dose: 100-300 mcg
• Frequency: Once, ~30-60 min before bed
• Duration: 2-4 week courses
• Route: Subcutaneous injection

Reported Benefits

• Promotes delta (deep) sleep
• Normalizes sleep architecture
• Reduces stress hormones during sleep
• Non-addictive
• Improved nocturnal GH release
• Circadian normalization

Potential Side Effects

• Morning grogginess (dose-dependent)
• Headache (rare)
• Vivid dreams
• Injection site irritation
