Research Overview

Somatostatin-14

Somatostatin-14 established the core inhibitory biology of the GH axis and is widely used to study receptor subtype signaling. It remains a benchmark ligand for comparing synthetic analogs and endocrine pharmacology.

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.
