Just the tail end of growth hormone, studied for its metabolic signaling.
A fragment, not the whole hormone.
AOD-9604 is a small piece of human growth hormone, the very tail end of the molecule.
(A peptide is a short chain of the building blocks your body uses.) Researchers took the 176-191 region of growth hormone, the stretch tied to its metabolic signaling, and modified it into a standalone fragment so it could be studied on its own.
AOD-9604 is studied for the metabolic-signaling side of growth hormone, separated from the parts that drive tissue growth.
The idea researchers poke at is whether that small tail region carries metabolic signaling on its own. A lot of the work is in cell and animal models. That is the mechanism. We're describing what gets studied, not promising an outcome.
The research so far
AOD-9604 shows up in metabolic and lipid-signaling research. You can dig into the literature on PubMed.
Featured angle
The 176-191 growth-hormone fragment
The headline is that AOD-9604 is a modified hGH 176-191 fragment studied for metabolic signaling without the full hormone's growth effects. Mostly preclinical work. None of it is a claim about what it does for a person.

The backstory
AOD-9604 came from asking which part of growth hormone carried its metabolic signaling.
Trimmed from hGH
Researchers isolated the 176-191 tail of the growth-hormone molecule.
Modified for stability
A small change at the end made the fragment easier to study.
Where it stands
A focused metabolic-research fragment. We're not telling you what it does for you, just where the studies look.
