Compound Reference Overview
| Field | Value |
|---|---|
| Name | Delta Sleep-Inducing Peptide (DSIP) |
| Reference Code | DSIP |
| Category | Cognitive / Sleep Regulation Peptide |
| Example Strength | 5 mg vial (varies by manufacturer) |
| Reference Range | 100–300 mcg nightly |
| Frequency | Once daily at bedtime |
| Key Safety Warning | May cause morning grogginess. Use caution in severe depression. Not FDA-approved. |
Mechanism of Action (Educational)
Delta Sleep-Inducing Peptide (DSIP) is a neuropeptide first isolated from rabbit cerebral venous blood. It has been associated with modulation of delta-wave sleep (deep sleep).
Experimental research suggests DSIP may influence hypothalamic-pituitary-adrenal (HPA) axis activity, modulate cortisol secretion, and impact stress and pain pathways. Its precise physiologic role remains incompletely characterized.
Indications (Literature / Off-Label)
- Insomnia
- Sleep quality improvement
- Stress and cortisol regulation
- Pain modulation research
Administration (Literature)
| Parameter | Details |
|---|---|
| Route | Subcutaneous or intramuscular |
| Frequency | Once nightly |
| Injection Sites | Abdomen, thigh, or deltoid |
| Timing | 30–60 minutes before bedtime |
Titration Schedule (Literature)
- Weeks 1–2: 100 mcg at bedtime
- Weeks 3+: 200–300 mcg nightly based on response
Reduce dose if morning grogginess occurs.
Pharmacokinetics (Literature)
- Approximate onset: ~25 minutes
- Sleep effects often observed the same night
- Short plasma half-life; functional effects may outlast measurable levels
Reconstitution & Concentration (Mathematical Illustration Only)
| Parameter | Value |
|---|---|
| Diluent | Bacteriostatic water (example only) |
| Reconstitution Volume | 2 mL (example) |
| Resulting Concentration | 2.5 mg/mL (2500 mcg/mL) |
| Stability | 21–28 days refrigerated (varies by formulation) |
Reconstitution Math Example
- 5 mg ÷ 2 mL = 2.5 mg/mL
- 0.04 mL = 100 mcg
- 0.08 mL = 200 mcg
- 0.12 mL = 300 mcg
