AOD-9604 is a synthetic peptide derived from a modified fragment of human growth hormone, specifically the amino acid sequence 176-191. It is primarily studied in metabolic research for its role in promoting lipolysis and inhibiting lipogenesis, contributing to fat breakdown and reduced fat accumulation. It has also been examined for its effects on body composition and adipose tissue regulation without the broader growth related activity of full length growth hormone. For laboratory research only — not for human use.
