"Premium grade DSIP validation."
DSIP (delta sleep-inducing peptide) is a nonapeptide with the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu and a molecular weight of 849 Da, originally isolated from brain tissue. It has been studied in neuropeptide and sleep research for its reported influence on slow-wave (delta) sleep in several species and on a range of physiological processes beyond sleep (Graf & Kastin, Neurosci Biobehav Rev 1984, PMID 6145137). DSIP research peptide is supplied lyophilized at ≥99% purity verified by HPLC, with identity confirmed by mass spectrometry and a batch-specific Certificate of Analysis (COA) included. Store lyophilized powder at −20 °C, protected from light and moisture. For laboratory research use only — not for human or animal consumption.
