DSIP (delta sleep-inducing peptide) has been studied inconsistently for sleep and stress since the 1970s. The evidence is weak and mixed.
Research context
Studied in relation to:
- Sleep/stress research
Points in its favour in the literature:
- Long research history
Caveats and unknowns:
- Inconsistent, weak evidence
- Not an approved therapy
Handling & reference data
Route in published researchSubcutaneous injection is the route most commonly described in the research literature. Usually before sleep.
Published clinical / research context (not instructions)Reported research ~100–300 mcg at night.
Storage (lyophilised)Lyophilised (freeze-dried) powder: refrigerate at 2–8 °C short-term, or freeze at −20 °C or below for long-term storage. Keep sealed and out of light.
Reconstituted solutionOnce reconstituted: keep refrigerated (2–8 °C), protect from light, do not freeze. With bacteriostatic water, commonly used within ~4 weeks; with plain sterile water, within ~24–48 h.
Worked reconstitution example (arithmetic only)e.g. 5 mg vial + 2 mL → 2.5 mg/mL.
