These guides report individual source methods and findings. They are not standardized or personal-use dosing protocols. A preclinical study does not establish a human regimen; original source records may change.

Human study

DSIP

Acute and delayed effects of DSIP (delta sleep-inducing peptide) on human sleep behavior.

Evidence sourceOriginal human study · PMID 6895513
Studied inSix healthy adult volunteers (four men and two women)
DesignDouble-blind crossover experiment; very small sample
Human protocolNo general protocol established by this single study

What researchers measured

  • Self-reported sleep pressure and sleep time during the 130-minute observation interval
  • Subsequent-night sleep onset, stage 1 sleep percentage and sleep efficiency
  • Behavioral and EEG observations

Methods reported in this human study

DSIP condition
Slow morning intravenous infusion of synthetic DSIP under study observation
Placebo condition
Placebo comparison in the double-blind crossover design

This was a six-person experimental study, not a standardized sleep regimen. The source reports morning slow intravenous infusion under observation; its findings do not establish personal use.
