What is DSIP?

DSIP (Delta Sleep-Inducing Peptide (nonapeptide)) is a 9-amino acid synthetic nonapeptide. Nonapeptide originally isolated from rabbit cerebral venous blood during sleep. Modulates sleep architecture by promoting delta wave (slow-wave) activity, interacts with opioid receptors and stress response systems, and demonstrates antioxidant activity in some models. Full mechanistic pathway incompletely characterised.

Frequently Asked Questions

How do I reconstitute DSIP?
Add 1–2mL bacteriostatic water to the lyophilized DSIP (delta sleep-inducing peptide) vial. DSIP is a nonapeptide that dissolves readily to a clear solution. Swirl gently.
How should DSIP be stored?
Store lyophilized at −20°C. Reconstituted: 2–8°C for up to 28 days. DSIP is a small, water-soluble nonapeptide with good stability in aqueous solution under refrigeration.
What purity is QSC DSIP and how is it verified?
QSC DSIP is ≥99% HPLC pure with MS-confirmed nonapeptide identity on every batch. COA is published on the product page and verifiable at verify.janoshik.com.
