AOD-9604 is a synthetic peptide based on a specific fragment of human growth hormone, and it is studied in metabolic research for that fragment's distinct profile. This overview covers what AOD-9604 is, the region of HGH it derives from, and the pathways it is examined in.
What Is AOD-9604?
AOD-9604 is a synthetic peptide corresponding to the C-terminal fragment (amino acids 176-191) of human growth hormone. It was characterised to isolate that specific region. Because it represents only the C-terminal fragment, it is studied as distinct from full-length growth hormone, which carries a much broader range of activity.
How Does AOD-9604 Work?
AOD-9604 is examined in metabolic research for its interaction with lipid-metabolism pathways — the cellular processes involved in how the body regulates lipid turnover — independent of the broader growth-signalling activity associated with the full hormone.
AOD-9604 and HGH Fragment 176-191
AOD-9604 and HGH Fragment 176-191 are closely related, both derived from the same C-terminal region of human growth hormone, and are frequently studied and discussed alongside one another.

Frequently Asked Questions
What is AOD-9604?
A synthetic peptide based on the C-terminal fragment (amino acids 176-191) of human growth hormone.
How is AOD-9604 different from HGH?
It represents only the C-terminal fragment, so it is studied as distinct from full-length growth hormone and its broader activity.
How does it relate to HGH Fragment 176-191?
Both derive from the same C-terminal region and are closely related research compounds.
What purity should AOD-9604 be?
Greater than or equal to 99% by HPLC with a per-batch COA.
