DSIP (Delta Sleep-Inducing Peptide) is a nonapeptide (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) originally isolated from rabbit cerebral blood by Monnier and colleagues in 1977. Despite its name, DSIP has been studied for a broad range of neuroendocrine effects beyond sleep induction, including modulation of the HPA axis, corticotropin-releasing hormone, and gonadotrophin-releasing hormone. It is also being investigated in oxidative stress models. NewChem's DSIP is supplied at ≥99% HPLC purity.
