Overview
Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nine-amino-acid neuropeptide found in the brain, hypothalamus, and pituitary gland.
What problem it targets: It targets severe insomnia, disrupted circadian rhythms, high nighttime cortisol spikes, chronic physiological stress, and chronic pain syndromes.
What It Does
• Restores natural slow-wave deep sleep: Crosses the blood-brain barrier to synchronize EEG delta rhythms in the brain, restoring restorative Stage 3 and Stage 4 deep sleep.
• Regulates the HPA axis: Modulates stress response pathways by lowering elevated nighttime ACTH and cortisol levels, bringing the nervous system out of chronic overdrive.
• Modulates central pain perception: Interacts with endogenous opioid and GABAergic pathways, exerting mild analgesic and mood-stabilizing effects.
• Realistic expectations: It is not a heavy narcotic sedative; it will not knock you out instantly. Instead, it re-trains natural sleep patterns over a few weeks, leading to deeper, uninterrupted sleep.
Reconstitution
| Vial size | BAC water / Solvent | Concentration |
|---|---|---|
| 2 mg | + 0.4 mL | 5 mg/mL |
| 5 mg | + 1 mL | 5 mg/mL |
| 10 mg | + 2 mL | 5 mg/mL |
Protocol
| Phase | Frequency | Dose | Units (2 mg/mL) | Units (3.33 mg/mL) | Notes |
|---|---|---|---|---|---|
| Weeks 1–2 | Nightly | 200 mcg | 10u | 6.0u | Start low and assess how your body responds before increasing. |
| Weeks 3–8 | Nightly | 200–500 mcg | 10–25u | 6.0–15.0u | Effective range. |
| Off | 2–4 weeks | – | – | – | Essential break between cycles. Skipping leads to tolerance and diminishing returns. Cycle: 4–8 weeks on, 2–4 weeks off. Timing: Pre-bed nightly, 15–30 min before sleep. Evidence: minimal human data; no dosing RCT. By sex: Unisex sleep peptide, same protocol for men and women, no cycle effect. |
Handling & Stacking
- Freeze-dried: -4°F.
- Reconstituted: 36–46°F.
- Best used within ~10–14 days (structure-based estimate, no published data); potency fades before the 28- day sterility limit, so keep it cold and dark and use it sooner.
- Protect from light.
- Deeper, more restorative sleep typically within the first few doses.
- Reduced overnight cortisol.
- Vivid dreams in some users.
- Supply math 2mg → 12 vials | 5mg → 5 vials | 10mg → 3 vials (8-wk @ 500 mcg × 7/wk)
