Product Information

The Neuropeptide That Tells Your Brain It's Time to Sleep

DSIP (10mg) will be available in Australia through Aus Peptide Supply 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 sleeping rabbits. It takes its name from its originally observed ability to induce delta wave sleep — the slow-wave, deep sleep stage associated with physical restoration and memory consolidation. Since its discovery, DSIP has been studied across a range of neuroendocrine and stress-related contexts, making it one of the more broadly researched neuropeptides in the sleep science literature.

What DSIP Is Studied For

  • Sleep Regulation — Studied for its role in promoting delta wave (slow-wave) sleep and improving sleep architecture
  • Stress Response — Investigated for its effects on stress resilience and cortisol modulation under physiological challenge
  • Neuroendocrine Function — Studied for interactions with the HPA axis and pituitary hormone release
  • Pain Sensitivity — Researched for its potential influence on nociceptive signalling

Supplied as lyophilized powder at high purity, 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?
DSIP (Delta Sleep-Inducing Peptide) is a neuropeptide first isolated in 1974 by Swiss researchers. It is named for its originally observed ability to induce delta wave (slow-wave) sleep in animals. It has since been studied for its broader roles in neuroendocrine regulation, stress response, and sleep architecture.
What does DSIP do in research?
The primary focus is sleep architecture — specifically delta wave (deep, slow-wave) sleep, which is the stage most important for physical recovery and restoration. Researchers also study DSIP for its effects on the HPA axis, stress resilience, and cortisol modulation. Some studies have also examined its influence on pain sensitivity and neuroendocrine signalling.
How do you reconstitute DSIP?
DSIP is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water (BAC water) immediately before use. Inject the BAC water slowly into the vial, directing the stream down the inside wall. Gently swirl to dissolve — do not shake. Once reconstituted, store at 2–8°C and use within 28 days.
Where to buy DSIP in Australia?
DSIP (10mg) will be available through Aus Peptide Supply with fast domestic shipping to all Australian states and territories. Every vial is dispatched from within Australia. Batch-specific CoA information will be available in our CoA library.
