Research Overview
AOD-9604 has been studied in metabolic research as a fragment of hGH, and in analytical chemistry for its detection and in-vitro metabolism.
Researchers use it to study how specific hGH regions behave independently of the full-length hormone.

AOD-9604: Research Background
AOD-9604 corresponds to residues 177–191 of human growth hormone, with an added N-terminal tyrosine. It was developed by researchers at Monash University, who studied the C-terminal region of hGH separately from the full-length hormone.
Published laboratory work examined the fragment in rodent adipose-tissue and lipid-metabolism models. Studies reported that it does not reproduce the full growth-promoting profile of intact hGH, which is why it is used to study how individual hormone regions behave.
AOD-9604 is also a subject of analytical chemistry research, including mass-spectrometry detection methods and in-vitro metabolism studies.
What the AOD-9604 COA Confirms
OxygenLab products are tested by independent third-party laboratories. HPLC reports purity as the main peak’s share of total peak area, and mass spectrometry confirms identity against the expected molecular weight of 1815.1 g/mol. Published certificates are on our COA page, and others are available on request; match the lot number on your vial to the report before use in an experiment.
