What HGH Fragment 176-191 is
This is residues 176 to 191 of the growth hormone molecule, a sixteen amino acid stretch from the C terminal end. It is a fragment of the hormone rather than the hormone, and it does not carry the full activity of somatropin. AOD-9604 is a closely related modified version of the same region.

Common questions
Is this the same as HGH?
No. It is a sixteen amino acid fragment of the 191 amino acid hormone, and it does not reproduce the activity of the whole molecule.
How does it relate to AOD-9604?
AOD-9604 is a modified version of the same 176-191 region, carrying an added tyrosine at the N terminus.
