DSIP 15MG

DSIP (delta sleep-inducing peptide) is a naturally occurring nonapeptide research compound studied in laboratory settings for its role in sleep-related and neuroendocrine signaling research. First isolated in 1977, DSIP is examined for its interaction with circadian and stress-response research models. Each vial from Central Peptides contains 15 mg of high-purity DSIP, third-party verified and supplied with a batch-specific Certificate of Analysis (COA) for research use only. As one of the most studied neuropeptides in sleep research, DSIP remains a frequently requested compound among Canadian laboratories.

DSIP Research Applications

DSIP is a nonapeptide — a chain of nine amino acids — with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu. First isolated in 1977 from the cerebral venous blood of rabbits, it is classified as an amphiphilic peptide, meaning it contains both water-attracting and water-repelling regions. The tryptophan residue at its N-terminus gives it a characteristic UV absorbance signature used for laboratory identification.

In controlled laboratory environments, researchers explore DSIP for its presence across the hypothalamus, limbic system, and pituitary, where it has been studied alongside various peptide and non-peptide mediators. Research has examined its potential involvement in sleep-associated signaling, circadian rhythms, and stress-resistance pathways in experimental models.

Common research areas where DSIP is examined include:

• Sleep-associated and delta-wave signaling research models
• Circadian rhythm and neuroendocrine regulation
• Stress-resistance and stress-protective pathways
• Neuropeptide localization and receptor research

Purity and Quality Verification

Every batch of DSIP sold by Central Peptides is manufactured under controlled synthesis and purification processes to ensure stability, consistency, and structural integrity for scientific research applications. Our compounds are independently tested and verified at 99% purity through High-Performance Liquid Chromatography (HPLC) and mass spectrometry.

Each order includes access to a batch-specific Certificate of Analysis, allowing researchers to verify identity, purity percentage, and testing details before use. This batch-level traceability is part of our commitment to transparency and quality control across our full research catalog. Researchers who require documented purity standards for their work can review the COA before and after purchase, ensuring every vial meets the same verified specification.

Storage and Handling

DSIP is supplied as a lyophilized (freeze-dried) powder for maximum stability during shipping and storage. Lyophilization removes moisture from the compound, which helps preserve its structural integrity over time and allows it to remain stable during transit. For long-term integrity, store the lyophilized compound in a cool, dry environment away from light.

Once reconstituted for research, DSIP is soluble in water and should be kept refrigerated at 2-8°C, or at -20°C for longer-term storage. To preserve compound integrity, aliquot the reconstituted material to avoid repeated freeze-thaw cycles, and use within an appropriate window to maintain consistency in research results.

Shipping Across Canada

Central Peptides ships DSIP and all research compounds across Canada in discreet, temperature-conscious packaging. Orders are typically processed within 24 hours and delivered within 3 to 5 business days. Free delivery is available on qualifying orders over the threshold listed at checkout.

As a Canadian-based supplier, we offer domestic fulfillment, which means faster delivery times and fewer customs complications compared to ordering from international sources. Every shipment is packaged to protect the compound during transit and to maintain privacy.
