DSIP

DSIP 10mg

DSIP (Delta Sleep-Inducing Peptide) is a synthetic nonapeptide consisting of nine amino acids, originally isolated from rabbit cerebral blood by Schoenenberger and Monnier in 1977. With the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, DSIP has been the subject of cellular and biochemical research literature for over four decades, with research contexts examining peptide-receptor interactions, cellular signaling, and neuropeptide biology.

Each vial contains 10mg of lyophilized DSIP in a sealed 3mL glass vial, verified through Mile High Compounds’ three-tier quality protocol: 7x independent third-party analytical testing, 4-vial batch conformity verification, and comprehensive heavy metal screening.

Research Background

DSIP has been investigated in research literature across several scientific contexts:

• Cellular neurobiology research — investigations into peptide effects on cellular signaling pathways in neuronal cell models
• Neuropeptide chemistry research — studies examining DSIP’s structural properties and stability across various analytical conditions
• Delta-wave cellular research — historical research on DSIP’s relationship to delta-wave electrophysiology in cellular and animal models
• Comparative peptide research — analytical studies positioning DSIP alongside other short-chain regulatory peptides in cellular research contexts
• Cellular oxidative stress research — studies examining cellular response in neuronal models under oxidative conditions
• Peptide-receptor binding research — investigations into DSIP’s cellular targets and signaling mechanisms

DSIP is historically significant in peptide research as one of the earliest characterized “sleep-related” peptides, originally identified in 1977 by Schoenenberger and Monnier through isolation from rabbit cerebral venous blood during electrically induced sleep states. Despite its name, DSIP’s exact cellular receptor and signaling mechanism remain areas of active research investigation. Foundational research is available through PubMed (pubmed.ncbi.nlm.nih.gov) and the National Institutes of Health’s PMC database (pmc.ncbi.nlm.nih.gov), where researchers can access peer-reviewed studies on DSIP cellular biology and neuropeptide research.

Analytical Verification

Every batch undergoes Mile High Compounds’ comprehensive analytical protocol:

• High-Performance Liquid Chromatography (HPLC) for purity quantification
• Mass Spectrometry (MS) for molecular weight and identity confirmation
• 14-day sterility testing
• Endotoxin analysis
• 4-vial batch conformity verification — statistically robust consistency testing across each production batch, exceeding the industry-standard single-vial sampling approach
• Heavy metal screening for lead, arsenic, cadmium, mercury, and additional trace metals
• Container and seal integrity verification

Batch-specific Certificates of Analysis (COAs) accompany every order, documenting full testing results across all verification protocols.

Reconstitution and Storage

• Lyophilized storage: Cool, dry location away from direct light; -20°C for long-term stability
