DSIP (Delta Sleep-Inducing Peptide) was identified in the 1970s in animals undergoing electrically-induced sleep. Early enthusiasm for its sleep-promoting effects was followed by inconsistent clinical results — efficacy data has been variable and DSIP has never reached approved therapeutic status. It remains in use through compounding pharmacies as a sleep adjunct.

DSIP Dosing by Use Case

Commonly cited protocols vary by what DSIP is being used for. The table below summarizes typical ranges reported in clinical practice and published literature.

Use caseTypical doseFrequencyCycle lengthNotes
Sleep onset / quality (PRN)100–300 mcgPre-bed, as needed1–2 weeks PRNMost common use. Continuous nightly use is not standard; PRN pattern is preferred.
Stress modulation (off-label)100–200 mcgOnce daily1–2 weeksOff-label and minimally validated; mechanism unclear.
Safety profile

DSIP has minimal reported acute toxicity, but its inconsistent efficacy means many users see little benefit.

  • Reported side effects in practice are minimal — injection-site reactions are the most common.
  • Inconsistent efficacy data — many users report no noticeable sleep effect.
  • Long-term safety beyond short PRN courses is not well-characterized.
  • Not FDA-approved.
Do not use if
  • Pregnancy or breastfeeding

DSIP Dosing FAQ

Published efficacy data is inconsistent. Some users report improved sleep onset and quality; others report no effect. If you're considering DSIP, set expectations for variability — and consider that simpler interventions (sleep hygiene, melatonin, behavioral therapy for insomnia) have stronger evidence.

Most protocols specify 30–60 minutes pre-bed. Subcutaneous injection in the abdomen or thigh.

Continuous nightly use is not the standard protocol — most practitioners suggest PRN dosing in 1–2 week courses with breaks. Continuous long-term use has not been well-studied.
