glp-1 receptor agonist mechanism Glucagon-like peptide-1 receptor: mechanisms and advances in therapy Current Insights, Advantages and Challenges

DSIP is a low-molecular-weight amphiphilic nonapeptide the selective membrane that separates circulating blood from brain tissue

This selectivity makes it the ideal GHRP for co-administration protocols with a GHRH, as it amplifies GH release without introducing hormonal confounding variables

Early pharmacology work described it as a selective growth-hormone secretagogue, with GH release and little ACTH or cortisol signal in the foundational studies

BBB damage may also allow zinc in the blood to enter the brain, and its ability to continuously block extrasynaptic GABA-A receptors may lead to neuronal hyperexcitability and seizures (97, 98)
