DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from cerebral venous blood during slow-wave sleep. Studied in preclinical models for its role in sleep architecture, stress-axis modulation, and neuroendocrine signaling. Synthesized to >99% purity and lyophilized for bench stability. Supplied for in-vitro and laboratory research use only.

Research Use Only — Not for Human Consumption
DSIP has been investigated across several neuroendocrine and sleep-regulatory pathways:
- Studied for promotion of slow-wave (delta) sleep patterns in animal models
- Modulates the hypothalamic-pituitary-adrenal (HPA) stress axis
- Implicated in circadian and neuroendocrine signaling pathways
- Investigated for stress-protective and antioxidant activity under physiological load
- Explored for influence on corticotropin and pituitary hormone regulation
Every batch of DSIP is independently tested by a US-based third-party laboratory. Our Certificate of Analysis confirms:

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) first isolated from cerebral venous blood during slow-wave sleep. In preclinical models it has been studied for promoting delta-wave sleep, modulating the hypothalamic-pituitary-adrenal (HPA) stress axis, and influencing neuroendocrine and circadian signaling. All activity described is from laboratory and animal research only.
Reconstitution and dosing parameters vary depending on the study model. Researchers typically reconstitute with sterile bacteriostatic water. We recommend consulting peer-reviewed literature for protocol design. We do not provide dosing guidance for human use.
No. All products sold by Clean Labs USA are strictly for laboratory and in-vitro research use only. They are not drugs, supplements, or food products and are not intended for self-administration or therapeutic use. Purchase constitutes agreement to our Research Use Only terms.
Every order ships with a batch-specific COA. You can also search our full COA library by SKU or batch number at trycleanlabs.com/coa-library. COAs include HPLC purity data, mass spec confirmation, and endotoxin results.
Store lyophilized DSIP powder at −20°C in a sealed vial, away from light and moisture. Under these conditions, shelf life exceeds 24 months. Once reconstituted, store at 4°C and use within 28 days. Do not freeze reconstituted solution.
