Overview

Product details.

DSIP 5mg — Delta Sleep-Inducing Peptide

Isolated from rabbit brain tissue in 1977 by Schoenenberger and Monnier, DSIP is a nine-amino-acid peptide that sits at an unusual intersection of neuroendocrine research — EEG sleep architecture, circadian rhythm regulation, and hypothalamic-pituitary stress signaling all converge on this one nonapeptide.

Research landscape

Preclinical studies have examined DSIP in EEG delta-wave sleep architecture, circadian rhythm gene expression, and hypothalamic neuropeptide signaling. Additional research has investigated interactions with the hormonal axis — ACTH and cortisol secretion patterns, LH release kinetics, and somatostatin pathway crosstalk. The nonapeptide has been characterized for its ability to cross experimental blood-brain barrier models, and a separate line of investigation examines its modulation of CRF (corticotropin-releasing factor) pathways and adrenal axis regulation in stress response models.
