What is AOD9604?
AOD9604 is a modified version of fragment 176-191, which is itself a smaller, modified piece of human growth hormone (HGH). AOD9604 was originally developed as an anti-obesity drug due to its lipolytic (fat burning) properties. This peptide is valued for the fact that it has limited effects beyond fat burning. It does not appear to affect IGF-1 levels or insulin levels and therefore is not a risk factor in promoting glucose intolerance or diabetes. There is also no evidence that the body forms antibodies against AOD9604 as it is similar enough in structure to HGH to avoid stimulating an immune system response
AOD9604 Research
AOD9604 and Obesity
AOD9604 was originally developed as an analogue of HGH with the express purpose of fighting fat. Phase 2b clinical trials were completed in Australia testing the drug in 300 obese individuals. The results of once daily administration of the peptide for 12 weeks showed that the drug tripled weight loss when compared to placebo and that the rate of weight loss remained steady during the trial period. This latter fact indicates that a resistance to the peptide is unlikely to arise and that longer-term treatment would result in even greater weight loss.
Joint Pain and Function
Research in rats indicates that injections of AOD9604 directly into arthritic joints can work in synergy with existing therapies to improve pain, reduce disability, and improve quality of life. Changes in both gross clinical exam and microscopic structure of cartilage in the affected joints indicates that AOD9604 is effective in treating the root cause of osteoarthritis and may work as both a treatment and preventative. Though AOD9604 is effective in reducing joint dysfunction on its own, it works better in combination with other therapies. It isn’t clear how the synergy arises, but additional research using the peptide may reveal novel pathways for improving cartilage growth, a notoriously challenging clinical problem.
AOD9604 and Heart Disease
Though fat reduction and weight loss directly reduce the risk of heart disease, there is evidence to suggest that AOD9604 has beneficial effects on the heart beyond its ability to reduce fat burden. It is thought that the peptide may directly affect metabolism in such a way to reduce complications separate from its effects on obesity. This is not unheard of, as drugs like pioglitazone and acipimox both reduce metabolic complications without treating obesity at all. It is thought that the secondary pathway by which AOD9604 causes fat loss, the pathway that is independent of beta-3-adrenergic receptor activation, may play a role in improving metabolic metrics even while it boosts fat loss.
