DSIP is widely studied in peptide neurobiology due to its ability to influence hypothalamic function, monoaminergic pathways, and circadian rhythm regulation
It is one of the most extensively researched peptides in the recovery category, with studies investigating its effects on tendon, muscle, and ligament healing, angiogenesis, and cytoprotective mechanisms
The data from both Phase 2 and Phase 3 programs is remarkable

[7] [2] By 1986, the major review of the field by Graf and Kastin concluded that the various physiological functions of DSIP and its mechanism of action remain to be established. [2] That sentence was written four decades ago and has not been superseded
