AOD-9604: Research Overview

AOD-9604 (Advanced Obesity Drug) is a modified fragment of human growth hormone (hGH), specifically the C-terminal portion (amino acids 177-191) with an added tyrosine at the N-terminus. It was developed to isolate the metabolic effects of HGH from its growth-promoting properties.

Development Background

AOD-9604 was developed at Monash University in Australia during the 1990s. Researchers identified that the C-terminal region of growth hormone contained specific metabolic activity distinct from the growth-promoting regions.

Key development points:

  • Isolated fragment 177-191 of hGH
  • Added tyrosine for stability
  • Retained metabolic activity
  • Eliminated IGF-1 stimulation
  • Mechanism of Interest

    Lipolytic Research

    AOD-9604 research has focused on:

  • Adipocyte metabolism
  • Lipid mobilization pathways
  • Fat oxidation studies
  • Metabolic rate research
  • IGF-1 Independence

    Unlike full hGH, AOD-9604 research has shown:

  • No significant IGF-1 elevation
  • No hyperglycemic effects
  • No growth-promoting activity
  • Targeted metabolic action
  • Research Applications

    Metabolic Studies

  • Adipose tissue research
  • Energy expenditure
  • Lipid metabolism
  • Metabolic syndrome models

    Frequently Asked Questions

    What makes AOD-9604 different from growth hormone?

    AOD-9604 is only a small fragment (amino acids 177-191) of the full growth hormone molecule, plus an added tyrosine. It lacks the growth-promoting regions and does not stimulate IGF-1, allowing study of metabolic effects in isolation.

    What does AOD stand for?

    AOD stands for 'Advanced Obesity Drug,' reflecting the original research focus on metabolic and weight-related effects of this hGH fragment.

    How should AOD-9604 be stored?

    Store lyophilized AOD-9604 in a freezer at -20°C for long-term storage. Once reconstituted, refrigerate at 2-8°C and use within 4-6 weeks. Never freeze reconstituted solution.
