DSIP (Delta Sleep-Inducing Peptide) Dosage Chart

DSIP is a nonapeptide studied since the 1970s for sleep modulation, stress and cortisol reduction, and pain. Be honest about the evidence: it is old and genuinely mixed, DSIP does not reliably induce sleep across studies, and its mechanism is not fully mapped. Research protocols use a small subcutaneous dose before bed.

AI-built tool. Cross-check critical values against authoritative sources before use.

Research Protocols

Dosage Protocols

Each row reflects a common research protocol variant. These are reference ranges derived from published literature and community research — not medical guidance.

Protocol 1

Standard Research Protocol

As studied, in short blocks

Dose

100-200mcg subcutaneous, before bed

Duration

As studied, in short blocks

The dose most sleep-research protocols circulate. Timed shortly before bed. DSIP clears from plasma within minutes, so it is dosed acutely rather than maintained.

Protocol 2

Stress / Cortisol Research

As studied

Dose

Up to ~300-500mcg subcutaneous

Duration

As studied

Higher-end research dosing explored for stress and cortisol endpoints. Older human work used microgram-per-kilogram intravenous dosing, which does not translate cleanly to a fixed subcutaneous dose.

Storage

Handling Notes

Lyophilized: -20°C long-term, 2-8°C short-term. Reconstituted with bacteriostatic water: refrigerate at 2-8°C and use within about 21-28 days. Swirl gently, never shake, and do not freeze the reconstituted solution.

Research Considerations

Cautions

  • The evidence is old and mixed. DSIP does not reliably induce sleep in controlled studies, so treat sleep claims as unproven.
  • Its very short plasma half-life and unclear mechanism make effects inconsistent between users.
  • DSIP is a research compound, not an approved therapy. Source only COA-verified material and be skeptical of strong marketing claims.
