DSIP Peptide Powder (Delta Sleep-Inducing Peptide, δ-Sleep Inducing Peptide, Emideltide) is a naturally occurring neuropeptide composed of 9 amino acids (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu, WAGGDASGE). First isolated from rabbit brain venous blood during electrically induced deep sleep in 1977, it is widely found in human brain tissue, cerebrospinal fluid, and peripheral tissues. This peptide has a stable molecular structure and well-defined physiological activity.

This product ensures high purity, low impurity content, and stable biological activity. Free from animal-derived contaminants, it meets the demand of Chinese purchasers for high-purity, cost-effective DSIP Peptide Powder for sleep regulation, neuroprotection, and stress modulation. Its gentle mechanism and extensive research data make it a favored neuro-regulatory peptide for overseas markets, suitable for research experiments, formulation development, and functional product R&D.

DSIP Peptide Powder is an endogenous neuropeptide that interacts with CNS receptors (specific receptors not fully determined), activating downstream signaling pathways. Its activity is circadian-dependent, most pronounced during biological night.

◇ Sleep Modulation – Regulates neurotransmitters (GABA, serotonin) to promote deep slow-wave sleep without affecting REM sleep. Enhances sleep quality safely, avoiding daytime drowsiness.

◇ Stress Regulation – Modulates HPA axis, reduces CRH activity, balances cortisol secretion, mitigates stress responses, anxiety, and stress-related sleep disorders.

◇ Neuroprotection & Immune Modulation – Antioxidant and anti-apoptotic effects protect neurons and support immune regulation, expanding applications in neuroscience research and formulation development.
