AOD-9604 vs HGH Fragment 176–191: What’s the Difference?
Since AOD-9604 is often described as an HGH fragment, it’s easy to confuse the two. In reality: HGH Fragment 176–191 is the natural sequence of amino acids (176 to 191) at the C-terminal end of human growth hormone (HGH). AOD-9604 is a modified version of this
