What is AOD-9604?

AOD-9604 is a modified fragment of human growth hormone (specifically amino acids 177-191 with an added tyrosine). It was designed to isolate the fat-metabolizing properties of growth hormone without its growth-promoting effects. It received GRAS (Generally Recognized as Safe) status from the FDA as a food additive, though it is not approved as a drug.

Cautions

  • Not FDA-approved as a drug
  • Clinical trial results for obesity were not conclusive enough for drug approval
  • Quality varies between sources

What We Don't Know

The Phase IIb clinical trial for obesity did not meet its primary endpoint, which raises questions about efficacy at studied doses.
