DSIP Protocol Guide
DSIP (Delta Sleep Inducing Peptide) is a naturally occurring nonapeptide first isolated from rabbit brain tissue, studied for its role in promoting delta wave sleep patterns, normalizing circadian rhythms, and modulating neuroendocrine stress responses including cortisol and ACTH secretion. Unlike sedative-hypnotics, DSIP appears to regulate sleep architecture without causing next-day drowsiness. This protocol covers reconstitution from a 5mg vial with 2mL bacteriostatic water, subcutaneous dosing at 100mcg nightly before bed, sleep quality improvement timelines, and stacking recommendations for comprehensive sleep optimization.
Protocol Overview
- Compound
- DSIP (Delta Sleep Inducing Peptide)
- Category
- Sleep / Neuroendocrine Peptide
- Mechanism
- Promotes delta wave sleep patterns, normalizes circadian rhythms, modulates cortisol and ACTH secretion, stress reduction via neuroendocrine regulation
- Structure
- Nonapeptide (9 amino acids)
- Half-Life
- ~15-25 minutes (prolonged downstream effects)
- Vial Size
- 5mg lyophilized powder
- Route
- Subcutaneous injection
- Frequency
- Once daily (30-60 min before bed)
- Cycle Length
- 4-8 weeks
Dosing Protocol
| Protocol | Dose | Frequency | Route | Duration |
|---|---|---|---|---|
| Standard Sleep | 100 mcg | 1x daily (before bed) | Subcutaneous | 4-8 weeks |
| Conservative Start | 50 mcg | 1x daily (before bed) | Subcutaneous | 1-2 weeks, then assess |
| Elevated Protocol | 200 mcg | 1x daily (before bed) | Subcutaneous | 4-6 weeks |
Key principle: Administer 30-60 minutes before intended sleep time. DSIP modulates sleep architecture rather than forcing sedation, so consistent nightly timing is important for entraining circadian rhythm benefits.
Reconstitution Instructions
Materials Needed
- DSIP 5mg lyophilized vial
- Bacteriostatic water (2mL)
- 3mL mixing syringe (18-20ga)
- Insulin syringes (29-31ga) for dosing
- Alcohol swabs
Reconstitution Steps
- Clean vial stopper with alcohol
- Draw 2mL bacteriostatic water
- Inject slowly down the vial wall
- Gently swirl (never shake)
- Wait 5 minutes for full dissolution
- Concentration: 2,500 mcg/mL
| Dose | Volume (2mL recon) | Insulin Syringe |
|---|---|---|
| 50 mcg | 0.02 mL | 2 units |
| 100 mcg | 0.04 mL | 4 units |
| 200 mcg | 0.08 mL | 8 units |
| 500 mcg | 0.20 mL | 20 units |
Administration Guide
Injection Sites

- Upper arm: Back of arm, alternate
Timing & Storage
- Timing: 30-60 minutes before bedtime
- Consistency: Same time nightly for circadian entrainment
- Vial duration: ~50 days at 100mcg/day
- Storage (reconstituted): Refrigerate 2-8°C, use within 30 days

Expected Timeline
Side Effects & Monitoring
Common Side Effects
- Injection site redness (mild, transient)
- Vivid dreams during initial dosing period
- Mild morning grogginess at higher doses
- Slight warmth or flushing after injection
DSIP is a naturally occurring peptide and is generally well-tolerated. Its short half-life limits systemic exposure, but long-term safety data in humans remains limited.
Precautions
- Limited long-term human clinical data
- May interact with sedative medications
- May modulate cortisol and ACTH levels
- Not recommended during pregnancy or breastfeeding
- Discontinue if excessive daytime drowsiness occurs
Stacking Recommendations
Compatible Compounds
- Epithalon: Telomere and pineal gland support for circadian optimization
- CJC-1295/Ipamorelin: Pre-bed GH release synergy during deep sleep
- Selank: Anxiolytic support to reduce pre-sleep anxiety
- BPC-157: Tissue recovery support during sleep
- Magnesium Glycinate: GABA receptor support for sleep quality
Popular Stacks
- Sleep Stack: DSIP 100mcg + Epithalon 5mg before bed
- Recovery Stack: DSIP + CJC-1295/Ipamorelin pre-bed
- Stress/Sleep: DSIP 100mcg + Selank 300mcg evening
Blood Work Recommendations
| Panel | Markers | Timing |
|---|---|---|
| Cortisol Panel | AM cortisol, DHEA-S | Baseline, Week 4 |
| Thyroid | TSH, Free T3, Free T4 | Baseline, Week 4 |
| Basic Panel | CBC, CMP | Baseline, Week 4 |
| Hormones | ACTH, prolactin | Baseline, Week 4 |
Monitoring cortisol and ACTH is particularly relevant since DSIP directly modulates these stress hormones. Thyroid markers help assess any neuroendocrine shifts from improved sleep patterns.
