DSIP

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide isolated from hypothalamic and peripheral tissues. It modulates sleep architecture by enhancing delta EEG rhythms, influences neuroendocrine hormones such as LH and GH, and may function as an adaptogen to improve stress resilience. Research indicates DSIP enhances mitochondrial oxidative phosphorylation and antioxidant activity, contributing to recovery and stress adaptation.
