 DSIP, also known as Delta Sleep-Inducing Peptide or Emideltide, is a synthetic linear nonapeptide. Its amino acid sequence is Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, with molecular formula C₃₅H₄₉N₁₁O₁₄ and molecular weight 847.85. The CAS number is 62568-57-4. This product appears as white lyophilized powder. The purity reaches 99% verified by HPLC testing. It is classified as high-grade synthetic polypeptide fine chemical raw material. Our factory implements strict quality control system across the whole production flow from raw material screening, peptide synthesis, purification, freeze drying to finished product packaging. Each batch is accompanied by complete COA certificate with full spectrum test data, to guarantee stable quality and consistent composition.

We maintain sufficient inventory and support flexible order specifications. Bulk wholesale and small batch supply are both available. Custom packaging service can be offered according to client requirements. Fast shipment and reliable logistics channels are arranged for global customers

DSIP can interact with neuroendocrine signaling pathways and participate in the transmission of multiple physiological signals. It is associated with the signal networks that govern circadian rhythm and sleep-related physiological states, and takes part in the regulation of the HPA axis to balance the body’s stress-related responses. This peptide exhibits free radical scavenging capacity and helps maintain cellular stability under oxidative conditions. It also links to endogenous hormone signaling pathways, supporting physiological adjustment after physical burden, and participates in signal transduction associated with pain perception.

This set of comparative visuals intuitively presents the shift of resting and daily energy states. On one side, it displays a state of restless rest and low daytime vitality; on the other side, it shows a serene resting condition accompanied by balanced daily energy. These images illustrate the variation of physical and mental states associated with circadian rhythm and neuroendocrine signaling balance, reflecting the difference in the body’s natural resting rhythm and daytime vitality performance.
