AOD-9604 (hGH Fragment 176–191)

Overview

AOD-9604 is a synthetic peptide derived from the C-terminal region of human growth hormone (hGH), corresponding to amino acids 176–191. It was originally developed to isolate the metabolic properties of growth hormone while avoiding the growth-promoting effects associated with the full-length hormone.

In research settings, AOD-9604 is primarily investigated for its role in lipid metabolism, adipose tissue regulation, and energy homeostasis. Unlike native hGH, AOD-9604 has not been shown to significantly stimulate insulin-like growth factor-1 (IGF-1) production, making it a valuable tool for studying metabolic pathways independently of broader endocrine signaling.

Researchers continue to explore its potential role in understanding fat metabolism, adipocyte function, and mechanisms involved in energy utilization.

Mechanism of Action

Current research suggests that AOD-9604 may influence metabolic pathways involved in fat mobilization and energy expenditure.

Proposed Mechanisms

✓ Promotion of lipolysis (breakdown of stored fat)

✓ Inhibition of lipogenesis (formation of new fat stores)

✓ Modulation of adipocyte signaling pathways

✓ Potential involvement of β3-adrenergic receptor-associated mechanisms

✓ Increased fatty acid mobilization in experimental models

Unlike full-length human growth hormone, AOD-9604 appears to act without significant activation of the growth hormone receptor pathway and without substantial increases in circulating IGF-1 levels in preclinical studies.

Important: Proposed mechanisms are based on experimental and preclinical research. Human physiological outcomes remain under investigation.
