AOD-9604

Modified HGH(176-191) C-terminal fragment studied for fat oxidation without raising GH or IGF-1.

AOD-9604 is the tail end of the growth hormone molecule — the specific fragment responsible for GH's fat-burning action, snipped away from the parts that raise blood sugar or grow tissue. The idea is to get GH's lipolytic (fat-releasing) effect without elevating GH or IGF-1 at all, so none of the growth-related risks apply. In practice the fat-loss effect is modest and the human data is thin, but its very clean safety profile makes it a low-stakes option, and there are early hints of joint and cartilage benefit too.
