DSIP
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first isolated from rabbit brain in 1974. It has been studied for its ability to promote slow-wave (delta) sleep, reduce stress responses, and normalise disrupted sleep patterns.
Quick facts
- Half-life
- ~30–40 minutes
- Administration
- Subcutaneous injection
- Primary use
- Sleep regulation, stress reduction
How it works
DSIP appears to modulate the activity of the hypothalamic-pituitary axis and influence neurotransmitter systems involved in sleep regulation, including serotonin and GABA pathways. Its precise mechanism remains incompletely understood.
Reported benefits
- Promotion of slow-wave (deep) sleep
- Reduced stress and normalisation of cortisol rhythms
- Potential use in insomnia and sleep disorder management
- Antioxidant properties observed in animal studies
Typical dosing protocol
Dosing
100–500 mcg subcutaneously, taken 30–60 minutes before sleep
Cycle length
Short cycles of 5–10 days; long-term use data is lacking
