Research Overview
Arginine Vasopressin
Animal and human studies indicate vasopressin can modulate hippocampal and limbic circuits involved in learning and memory. The effect size is context dependent, and results vary by dose, route, and baseline cognitive state.
hGHRH(1-44)
Human GHRH(1-44) amide has been used extensively to characterize hypothalamic control of pituitary somatotrophs and the downstream GH/IGF-1 axis. It remains a standard comparator in studies of GHRH agonism, secretion dynamics, and receptor pharmacology.
