Overview
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first identified for its association with sleep, and studied for effects on sleep, stress and pain.
How It's Thought to Work
Its exact mechanism is not well established; research has explored roles in modulating sleep architecture, stress hormones, and neurotransmitter systems.
What the Research Says
Human evidence is old and limited; results on sleep have been mixed and it remains poorly characterized.
Regulatory & Legal Status
Not FDA-approved. Sold as a research chemical.
Safety Considerations
Limited human safety data; unregulated product quality. Consult a qualified clinician.
