Description
DSIP Spray delivers the classic sleep-research nonapeptide in a convenient pre-mixed bottle. Limitless Life Nootropics prepares it in the USA in Premium and Non-Lyophilized grades.
What Is DSIP Spray?
Delta Sleep-Inducing Peptide is a nine-amino-acid neuropeptide associated with slow-wave sleep, stress hormone regulation and circadian timing. Because it is small, it has been investigated for its ability to reach the brain after peripheral or intranasal delivery.
The spray format offers metered, repeatable dosing without reconstitution. That consistency is valuable in sleep studies, where timing and dose need to be controlled closely across many sessions.
Choose Premium or Non-Lyophilized grade. The product may contain trehalose as a lyoprotectant.
Research Applications
Published preclinical work has examined this spray across several areas of investigation:
- Intranasal neuropeptide delivery
- Sleep onset and slow-wave sleep
- Circadian phase studies
- Stress response and cortisol
- Comparisons with lyophilized peptide
Researchers can review peer-reviewed studies on delta sleep-inducing peptide through the National Library of Medicine (PubMed) database.
