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(1-40)OH
Human GHRF(1-40)OH has been studied to understand how truncation of the native hormone changes biological potency and half-life. It is a common research tool for mapping minimal active sequences within the GHRH family.
