Human growth hormone (HGH) does a lot of things. Some of those things — like making your muscles grow or affecting blood sugar — aren't what every researcher wants to study. AOD-9604 is the answer to a specific question: what if you could keep just the fat-metabolism part?
How it was made
Scientists at Monash University in Australia took the very last 16 amino acids of human growth hormone and tweaked them. The result was AOD-9604 — a peptide that, in animal studies, seemed to influence fat metabolism without the broader hormone effects of the full HGH molecule.
What labs have studied
Most AOD-9604 research has focused on lipolysis (breaking down stored fat) and lipogenesis (preventing new fat storage) in animal models. Some studies have also looked at its possible role in cartilage repair, since growth hormone is involved in joint tissue.
Human clinical trials have been relatively limited and produced mixed results, especially for weight loss outcomes.
Why researchers still find it useful
AOD-9604 lets scientists isolate one slice of growth hormone biology. That kind of precision is hard to come by. Even when a peptide doesn't pan out as a treatment, it can still teach researchers a lot about how the original hormone works.
Important: AOD-9604 is provided for laboratory and research use only. Not for human consumption.
