Research Overview

Desmopressin

The literature is mixed, but desmopressin has shown memory-related effects in selected populations and experimental paradigms. Its cognitive effects are usually discussed as a vasopressin-pathway probe rather than a primary nootropic.

hGHRH(1-37)OH

Human GHRF(1-37)OH has appeared in studies examining how loss of C-terminal residues affects biological activity at the GHRH receptor. It is often used alongside other fragments to define structure-activity relationships within the GHRH family.
