DSIP (5mg), or Delta Sleep-Inducing Peptide, is provided as a lyophilized research peptide for controlled work on sleep and neuroendocrine regulation. It is commonly used in models evaluating circadian rhythms, stress responses, and interactions between central nervous system signaling and hormonal outputs. 

Our 5mg vials suit pilot studies, time-course analyses, and receptor-binding assays where precise dosing and repeat runs are required. Material is US lab tested, and a Certificate of Analysis is available so you can document purity, identity, and batch details in study records. The vial is packaged for convenient reconstitution into suitable aqueous vehicles used in laboratory settings. DSIP from Health and Science Peptides is sold strictly for research use only and must not be used for human insomnia treatment or any clinical application.
