AOD9604 is a peptide fragment (Fragment 177-191) of the C-terminus of Human Growth Hormone to which a tyrosine is added at the N-terminal end. AOD stands for “Anti-Obesity Drug”. This peptide has an amino acid sequence that mimics the lip lytic region of human growth hormone (the region of this hormone thought to be responsible for burning fat) and it has been promoted variously as a weight loss supplement, as an aid to muscle and cartilage repair, and a treatment for osteoarthritis by its manufacturers. Studies have suggested that AOD9604 is more effective than its predecessor AOD9401. Recent clinical research studies have shown that AOD9604 did show a reduction of body fat in the mid abdominal area in both obese, over-weight, and average built people.
