DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide (9 amino acids) first isolated in 1977 from the cerebral venous blood of rabbits. It crosses the blood-brain barrier and acts as a neuromodulator across multiple systems, and is studied for its effects on delta-wave electroencephalographic activity, circadian-rhythm signaling, and hypothalamic-pituitary-adrenal axis regulation in animal models. Additional preclinical research examines its modulation of stress-hormone signaling, thermoregulation, and nociceptive pathways. Despite decades of investigation, its receptor and mechanism remain incompletely defined, which makes it a continuing subject of neurochemistry research. DSIP is supplied as a lyophilized reference compound for sleep-neurobiology, circadian-rhythm, and neuroendocrine research.

Frequently Asked Questions
How does buy one, get one free work?
Every research compound on the site is BOGO. Add the quantity you want to pay for and we automatically double it — the free vials are the same size and the discount is applied at checkout with no code.
Are your products third-party tested?
Yes. Every batch is independently tested for identity and purity by HPLC and mass spectrometry at U.S. accredited labs, and a Certificate of Analysis is available for each batch.
What purity can I expect?
All compounds are 99%+ purity, verified by HPLC.
How should this be stored?
Store lyophilized (freeze-dried) material cool and dry; refrigerate once reconstituted at 2–8°C. Refer to the product details for compound-specific guidance.
How fast do you ship?
Orders dispatch within 24 hours Monday–Friday in temperature-controlled, tamper-evident packaging with tracking.
Are these for human use?
No. All products are sold strictly for in-vitro research and laboratory use only and are not for human or veterinary use.
