Summary
DSIP (Delta Sleep-Inducing Peptide) is a neuropeptide originally isolated from venous blood of rabbit brains in a sleep state. It is studied for promoting slow-wave sleep, reducing stress responses, and analgesic effects. Its exact mechanism remains incompletely understood.
Originally isolated from a sleeping rabbit's brain, this tiny 9-amino acid peptide appears to promote deep, slow-wave sleep — the most restorative phase of the sleep cycle. Its exact mechanism isn't fully understood, but it's thought to work through the brain's opioid and stress-response systems. One of the more speculative compounds in the catalog due to limited modern research.
Mechanism of Action↓
May act on delta-opioid receptors and modulate opiate systems. Proposed effects on ACTH release (corticotroph inhibition), temperature regulation, and circadian rhythm entrainment. Increases slow-wave (delta) EEG activity in sleep studies.
Half-life: ~15–30 minutes
Research Dosing Ranges↓
200–500 µg per dose
Once daily, subcutaneous or intravenous (research)
Typically administered 30–60 minutes before sleep in research protocols.
Reconstitution Guidance↓
BAC water: 1 mL
Resulting concentration: mg/mL depends on vial size
Standard reconstitution. 200 µg dose: use a graduated 0.3 mL syringe.
Storage & Stability↓
Refrigerate. Use reconstituted solution within 14 days.
Known Side Effects / Contraindications↓
Limited data. Mild drowsiness, lightheadedness reported.

Concentration: 5 mg ÷ 3 mL = 1.67 mg/mL (1667 µg/mL)
Dose needed: 250 µg = 0.2500 mg
Volume per dose: 0.2500 mg ÷ 1.67 mg/mL = 0.1500 mL
On U-100 syringe: 150.0 µL = 15.0 units
Total doses in vial: 5 mg ÷ 0.2500 mg = 20.0 doses
