Research Information
Mechanism of Action
DSIP is a naturally occurring neuropeptide:
- Delta-wave induction: Studied for enhancement of delta EEG activity during sleep
- Stress response: Research on modulation of ACTH and cortisol pathways
- Endocrine effects: Investigated for interactions with LH, GH, and somatostatin release
Published Research
