AOD 9604 is a fragment of GH (growth hormone) polypeptide (amino acids 176-191)that has been shown to have lipid-reducing effects, similar to but more effective than GHon account of it not having adverse side effects of unmodified GH. AOD 9604 can regulate fat metabolism by stimulating lipolysis (the breakdown or destruction of fat) and inhibits lipogenesis (the transformation of nonfat food materials into body fat) both in laboratory testing; and in humans and animals. Recent studies also demonstrate that AOD 9604 possesses other regenerative properties associated with growth hormones. Currently, trials are underway to show the application of AOD 9604 in osteoarthritis, hypercholesterolemia, and bone and cartilage repair.
