A fragment of human growth hormone that targets fat metabolism without the growth-promoting effects of full HGH.
AOD-9604 is a modified fragment of human growth hormone (hGH) corresponding to amino acids 176–191 of the hGH sequence. Originally developed by Monash University in Australia as part of an anti-obesity drug program, it was designed to isolate the lipolytic (fat-burning) properties of HGH without triggering the growth-promoting, insulin-desensitizing, or carcinogenic risks associated with full HGH administration. The peptide completed Phase IIb clinical trials for obesity and received GRAS (Generally Recognized as Safe) status from the FDA for use as a food additive, making it one of the few research peptides with a formal safety assessment. Beyond fat loss, preclinical research has suggested potential applications in cartilage repair and osteoarthritis, adding to its research interest.

“A fragment of human growth hormone that targets fat metabolism without the growth-promoting effects of full HGH.”
AOD-9604 stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat formation) by activating beta-3 adrenergic receptors in adipose tissue, directly mimicking the fat-metabolizing action of the C-terminal region of HGH. Critically, because it lacks the N-terminal portion of HGH responsible for IGF-1 stimulation, it does not elevate blood glucose, raise IGF-1 levels, or promote cell proliferation. The peptide also appears to activate AMP-activated protein kinase (AMPK), a key cellular energy sensor that promotes fat oxidation. In cartilage studies, it has been shown to stimulate proteoglycan synthesis and inhibit matrix metalloproteinases (MMPs), suggesting a role in joint tissue preservation independent of its metabolic effects.
When sourcing AOD-9604 for research purposes, the following quality benchmarks should be verified before use.
>98% (verified by HPLC)
Must be provided by supplier
<0.1 EU/mg (prevents bacterial contamination)
Manufactured in cGMP-certified facility
Independent lab verification preferred
Lyophilized: room temperature up to 3 months, refrigerated up to 2 years. Reconstituted: refrigerate and use within 30 days.
