About
DSIP was identified in the 1970s by Schoenenberger and Monnier from the venous blood of rabbits induced into sleep, on the theory that whatever was circulating during deep sleep would induce it in others. The mechanism story has never fully resolved.
Read the full research guideWhy people choose it
- Subjectively deeper sleep on the nights it works. Users describe waking with less of the early-morning shallowness
- No next-day grogginess, in contrast to benzodiazepines or Z-drugs
- Possible blunting of late-night cortisol in some users, which can help if 3 AM wake-ups are the pattern
- Useful as an experimental tool when you have already tried the boring sleep-hygiene fixes and want something with a different mechanism than melatonin
