What AOD-9604 is

hGH fragment, plain

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.

It sits on the Weight + Metabolism shelf alongside other metabolic-research compounds like Tesamorelin.

What it actually does

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.

Growth-hormone tail

Built from the 176-191 region of hGH.

Metabolic signaling

The angle researchers isolate and study.

Research only

We stock it for research. The studies write the conclusions, not us.

A way to study growth hormone's metabolic side without the rest of the molecule.

The backstory

AOD-9604 came from asking which part of growth hormone carried its metabolic signaling.

  1. Trimmed from hGH

    Researchers isolated the 176-191 tail of the growth-hormone molecule.

  2. Modified for stability

    A small change at the end made the fragment easier to study.

  3. Where it stands

    A focused metabolic-research fragment. We're not telling you what it does for you, just where the studies look.
