Key Findings
- A suboccipital dose of 15‑20 µg/kg dsip caused electrographic and behavioral delta‑sleep in cats and rats within 15‑25 minutes.
- The peptide raised the EEG threshold to sound stimulation, indicating reduced sensory responsiveness during induced sleep.
- Paradoxical (REM) sleep was delayed by 50‑90 minutes, suggesting the peptide disrupts normal sleep progression.
Practical Outcomes
- The peptide can force deep sleep in rodents, but it also alters normal sleep cycles and has only been tested in animals with invasive administration. There’s no evidence it works safely or effectively in humans, so it isn’t a practical or actionable tool for biohackers at this time.
Summary
In cats and rats, injecting a tiny amount of the peptide dsip under the skull quickly puts them into deep (delta) sleep, makes them less responsive to sounds, and delays the start of REM sleep, showing that the drug‑induced sleep is different from normal sleep. The study was done only in animals, so it doesn’t give a usable protocol for people.
Abstract
Suboccipital administration of the oligopeptide to adult cats and white rats in a dose of 15 and 20 micrograms/kg induces the appearance of electrographic (delta-sleep) and behavioral sleep within 15-25 min. Administration of the oligopeptide induces a substantial increase in the thresholds of the response of the EEG to phonostimulation. A substantial lag (50-90 min) in the onset of paradoxical sleep is noted, which is considered by the authors as a manifestation of inhibition, exerted by the neuropeptide on the further development of the sleep mechanisms. On the basis of the data obtained it is concluded that natural sleep and that induced by the neuropeptide are nonequivalent.
