Growth-hormone fragment
AOD-9604 contains a modified sequence from the end of the growth-hormone molecule. Preclinical research suggests it does not engage the conventional growth-hormone receptor in the same way as full-length hormone.

Compound guide
A pathway-focused guide to molecular mechanisms, published evidence, and the limits of interpretation.
Overview
AOD-9604 is a modified peptide derived from the C-terminal region of human growth hormone and was developed to study lipid metabolism separately from full-length growth-hormone signaling.
Animal studies examined lipolysis, fat oxidation, and beta-adrenergic pathway involvement without conventional growth-hormone receptor activation.
Preclinical findings did not translate into a statistically significant primary weight-loss result in a larger human study reviewed by FDA. It should not be described as a proven fat-loss benefit.
Research model
These receptors, enzymes, and signaling networks define the primary laboratory questions associated with this research material.
AOD-9604 contains a modified sequence from the end of the growth-hormone molecule. Preclinical research suggests it does not engage the conventional growth-hormone receptor in the same way as full-length hormone.
Animal studies connect the fragment's activity with beta-adrenergic signaling in adipose tissue. This network can activate cyclic-AMP-dependent enzymes that release stored fatty acids from fat cells.
Preclinical work reported shifts toward fatty-acid oxidation and away from lipid accumulation. The exact direct target responsible for those observations remains uncertain.

Read the evidence
One important note
The molecular model is based largely on animal and cell studies. In the larger human obesity study reviewed by FDA, AOD-9604 did not produce a statistically significant weight-loss advantage over placebo.
