Research Overview
DSIP is a nonapeptide of endogenous origin, notable for its ability to cross the blood-brain barrier and engage multiple receptor classes in preclinical research systems. Animal studies have examined its capacity to modulate slow-wave sleep parameters and influence the periodicity of sleep-wake cycles, while separate lines of preclinical inquiry have addressed its interactions with sigma receptors and hypothalamic stress-response pathways. Its neuroendocrine profile has been investigated across multiple hormonal axes, including corticotropin and somatotropin signalling. Supplied exclusively for laboratory and research use.
DSIP was first identified in the 1970s through bioassay-driven isolation from thalamic venous blood of sleeping rabbits, and has since been studied in circadian rhythm research, neuroendocrine axis modulation, and sleep-wake cycle signalling in multiple preclinical species. In animal models, DSIP administration has been associated with changes in slow-wave (delta) sleep parameters and altered corticotropin and growth hormone secretion patterns. Research into its sigma receptor interactions adds another dimension to its profile as a neuromodulatory research tool. All outcomes referenced pertain to preclinical models and do not constitute evidence of clinical efficacy or safety in humans.

COA / Testing
Batch documentation and third-party testing information are available for batch BME-DSIP5M-A. COA previews appear only when documentation exists for the active batch.
Storage & Handling
DSIP lyophilized powder should be stored at −20°C in a sealed vial, protected from light and moisture to prevent peptide degradation. Freeze-thaw cycling diminishes compound integrity; aliquot samples prior to reconstitution to preserve stock material. Reconstituted solutions should be maintained at 4°C and used within intervals defined by laboratory protocols.
Shipping & Returns
Orders are processed on business days. Packaging is selected to maintain compound integrity in transit. Shipping timelines and return conditions are outlined in full in the Shipping & Returns policy — review before checkout if you have specific requirements. For orders with time-sensitive research schedules, contact support before placing your order.
