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.

Capromorelin

Research consistently shows capromorelin activates the ghrelin receptor pathway and increases food intake. Human development has been less prominent than veterinary use, but the compound remains a relevant GH secretagogue prototype.
