AOD9604 is a peptide that is considered to be a modified fragment of growth hormone that has been shown to reduce body fat and regulate metabolism. In a study conducted by Ng et. Al, obese Zucker rats were received a dose of 500 micrograms/kg of body weight over the course of 19 days. After the 19 days, researchers discovered that compared to the control group, the experimental group of rats lost 50% body weight. Additionally it was noted that in the rats treated with AOD9604, there were increased rates of lipolytic activity, as well as no negative effect on insulin sensitivity which has been seen in animals treated with human growth hormone (https://pubmed.ncbi.nlm.nih.gov/11146367/.
