Description
DSIP Capsules | Delta Sleep-Inducing Peptide — Neuroendocrine Research
DSIP (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) is a naturally occurring neuropeptide isolated from rabbit brain thalamus, identified for its ability to induce delta sleep in preclinical models. Beyond sleep regulation, DSIP demonstrates broad neuroendocrine activity including HPA axis modulation, opiate tolerance reduction, and antioxidant properties. These capsules (5mg per capsule, 30 capsules) support oral delivery research.
Mechanism of Action
- Delta wave promotion — induces slow-wave (delta) sleep architecture in animal models; modulates sleep-wake cycle regulation
- HPA normalisation — reduces excess cortisol and ACTH secretion in stressed animal models
- Opioid tolerance reduction — studied in models of opiate dependence for reducing tolerance development
- Antioxidant activity — demonstrated free radical scavenging properties in in vitro assays
Research Areas
DSIP is studied in sleep disorders, stress biology, HPA axis research, opioid pharmacology, and circadian rhythm modulation. Frequently paired with Selank capsules and Semax capsules for comprehensive neuroendocrine panels.
