Research Overview

Anamorelin

Trials in cachexia populations showed increased appetite and modest gains in body weight and IGF-1. Regulatory progress has varied by region, but it remains a well-studied ghrelin agonist in the GH space.

hGHRH(1-32)NH2

Human GHRF(1-32)NH2 is used in basic and translational studies to evaluate how the active N-terminal region of GHRH drives pituitary hormone release. It helps define the lower bound of sequence length needed for meaningful biological activity.
