AOD-9604 is a well-known research compound within metabolic research. In this guide we explain, research-only, what AOD-9604 is and what it is studied for — strictly without health or weight-loss claims.
AOD-9604 is a synthetic fragment of human growth hormone (hGH 176-191) that is studied in research in relation to fat metabolism. It is not an approved medicine and is offered exclusively for research, ≥99% pure with documentation per batch.
What is AOD-9604?
AOD-9604 is a synthetic fragment of human growth hormone, corresponding to amino acids 176 to 191. It is therefore not a complete growth hormone, but a small, specific portion of it. That delimitation is exactly what makes it a targeted subject of study. New to peptide science? Read what peptides are.
How does AOD-9604 work in research?
In research, AOD-9604 is studied in relation to fat metabolism (lipolysis). The fragment is derived from the part of growth hormone that science associates with fat metabolism. Because it is only a fragment, research looks at this specific aspect, separate from the broader effects of the complete hormone. These descriptions come from preclinical research and are no proof of effect in humans.
AOD-9604 versus other metabolic compounds
Whereas AOD-9604 is a growth-hormone fragment, other metabolic research compounds act via entirely different routes. For example, MOTS-C is a mitochondrial peptide and Retatrutide a triple agonist — read more in What is Retatrutide. Each molecule calls for its own research design.
AOD-9604 is exclusively for laboratory and research purposes. It is not a medicine, not a weight-loss product and not intended for human or animal consumption. No medical, health or weight-loss claims are attached to it.

Frequently asked questions about AOD-9604
What is AOD-9604?
AOD-9604 is a synthetic fragment of human growth hormone (hGH), corresponding to amino acids 176-191. Within metabolic research it is studied in relation to fat metabolism, and it is not an approved medicine.
How does AOD-9604 work in research?
In research, AOD-9604 is studied in relation to fat metabolism (lipolysis). It is derived from the part of growth hormone associated with fat metabolism but is expected to lack the broader growth-hormone effects. This concerns preclinical research.
Is AOD-9604 a growth hormone?
No. AOD-9604 is a small fragment of growth hormone, not the whole hormone. It is precisely that delimitation — a specific fragment — that makes it interesting as a subject of study.
Is AOD-9604 approved for weight loss?
No. AOD-9604 has been studied in the past but is not an approved medicine for weight loss. At Peptide Lab it is offered exclusively as a research compound.
