Delta Sleep-Inducing Neuropeptide Research Compound
DSIP (10mg) will be supplied in Australia by Aussie Peptides with fast domestic shipping to all states and territories.
Delta Sleep-Inducing Peptide (DSIP) is a neuropeptide first isolated in 1974 from the cerebral venous blood of rabbits induced into slow-wave (delta) sleep. It is studied for sleep regulation, stress response, and neuroendocrine modulation. Distinct from sedative pharmaceuticals, DSIP is studied for promoting natural sleep architecture — specifically the deep delta-wave sleep stages associated with recovery and hormonal regulation.
DSIP levels fluctuate with the sleep-wake cycle and decline with chronic stress, making it a research focus in the sleep–cortisol–recovery relationship.
Key Research Areas
- Sleep Architecture — Studied for delta-wave sleep promotion without sedation or dependence
- Cortisol Regulation — Associated with reduced cortisol and ACTH levels in stress models
- HPA Axis — Studied for HPA-axis and stress response modulation
- Sleep-Linked GH Release — Studied in connection with nocturnal GH release and recovery cascades
- Neuroprotection & Antioxidant — Emerging research on cellular antioxidant properties
Supplied as lyophilized powder at 99.002% purity as reported on the CoA, verified by HPLC and mass spectrometry. 10mg per vial. Fast domestic shipping across Australia, with batch-specific CoA information available in our CoA Library.

Frequently Asked Questions
What is DSIP?
Delta Sleep-Inducing Peptide (DSIP) is a neuropeptide first isolated in 1974 from the cerebral venous blood of rabbits induced into slow-wave (delta) sleep. It has since been studied for its role in sleep regulation, stress response modulation, and neuroendocrine function. Unlike pharmaceutical sleep aids, DSIP is not a sedative — it is researched for promoting natural sleep architecture, particularly deep, restorative delta-wave sleep.
How does DSIP work?
DSIP is believed to modulate the hypothalamic-pituitary-adrenal (HPA) axis — the body's central stress-response system. Research suggests it reduces cortisol and ACTH output, supports growth hormone release during sleep, and may promote the neurological conditions associated with deep delta-wave sleep. It works through neuroendocrine modulation rather than direct sedation.
What does the research show about DSIP?
Research has demonstrated DSIP's association with improved slow-wave sleep, reduced cortisol levels, and modulation of the HPA axis stress response. Animal studies have shown effects on sleep architecture and stress resilience. Emerging research suggests potential neuroprotective and antioxidant properties. Human research is more limited but supports the cortisol-modulating and sleep-quality effects seen preclinically.
How do you reconstitute DSIP?
DSIP is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water immediately before use. Inject BAC water slowly into the vial along the inside wall and gently swirl to dissolve — do not shake. Once reconstituted, store at 2–8°C and use within 8–12 weeks.
How should DSIP be stored?
Store lyophilized DSIP vials at -20°C, away from light and moisture. After reconstitution, refrigerate at 2–8°C and use within 8–12 weeks. Do not freeze reconstituted solution.
