Tag: Sleep

## Mechanism
A nonapeptide originally isolated from rabbit brain during electrical sleep induction. Research has examined effects on delta-wave sleep, stress hormone modulation (lowering cortisol, normalizing ACTH), and opioid withdrawal.

## Research areas
- Sleep architecture (delta wave activity)
- Chronic stress and HPA-axis modulation
- Opioid withdrawal (older studies)

## Common research protocols
- Evening subcutaneous research: Pre-sleep subcutaneous dosing in human sleep studies.

## Study summaries
- "DSIP and sleep regulation: review" — Neuropeptides (1984): Early human and animal studies of sleep and stress effects.

## Considerations
- Not FDA-approved.
- Modern replication is limited.
