DSIP
DSIP
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide (9 amino acids) first isolated in 1977 from the cerebral blood of rabbits during induced sleep. Named for its ability to promote delta-wave (deep, slow-wave) sleep, it readily crosses the blood-brain barrier and acts as a neuromodulator across multiple systems. Research shows DSIP influences sleep architecture, circadian rhythm, and the body's stress response, with studies reporting normalization of disturbed sleep and modulation of hormonal and neurotransmitter activity. Additional findings suggest it helps regulate stress-hormone signaling, body temperature, and pain perception, and may buffer the physiological effects of stress. Despite decades of investigation, its precise receptor and mechanism remain incompletely defined, making it a compelling subject in neurochemistry. These properties make DSIP a widely studied model compound in sleep, circadian-rhythm, stress-resilience, and neuroendocrine research.

Frequently Asked Questions
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. Refer to the product details for compound-specific guidance.
How fast do you ship?
Orders generally ship within 1–2 business days in temperature-controlled, tamper-evident packaging with tracking.
Are these safe for human use?
No. All products are sold strictly for in-vitro research and laboratory use only and are not for human or animal consumption.
