DSIP

DSIP (Delta Sleep-Inducing Peptide) was isolated from cerebral venous blood of sleeping rabbits in 1977 by Schoenenberger and Monnier, who observed its ability to induce slow-wave sleep. What it is: It is a synthetic 9-amino-acid peptide categorized under Tissue Repair/Immune (neurobiology). Proposed Mechanisms & Research Findings: It modulates neuromodulatory activity, interacting with GABAergic, glutamatergic, and opioid systems to induce delta-wave sleep and reduce stress. Regulatory & Safety Status: It is not FDA approved. It remains an investigational peptide. Sourcing from online vendors poses serious purity and safety concerns. Athletic & Anti-Doping Status: It is not prohibited by WADA, although athletes should monitor sedative use rules.
