AOD-9604: What It Is and Its U.S. Regulatory Status

What is AOD-9604?

AOD-9604 is a synthetic peptide based on the tail end of human growth hormone, the part of the molecule spanning amino acids 176 to 191. It includes an extra amino acid, tyrosine, added at the start of the chain. The letters AOD stand for anti-obesity drug, which reflects what it was originally developed for.

Unlike full-length growth hormone, AOD-9604 was designed to be a fragment only. It is not the same as growth hormone and is not a growth hormone product.

Research history

AOD-9604 was developed in Australia in the 1990s. It was studied in clinical trials for obesity in the 2000s, but it was not developed into an approved medicine. Development for that purpose was stopped.

U.S. regulatory status

Current status: Not FDA-approved.

AOD-9604 is not the active ingredient in any FDA-approved medicine, and the FDA has not found it safe and effective for any use in people.

The World Anti-Doping Agency considers AOD-9604 a prohibited substance in competitive sport, as a compound without approval for human use.
