Is HGH Fragment 176-191 the same as AOD-9604?
Yes, chemically. This site's HGH Fragment 176-191 profile says the product sold under that name is the same changed piece of growth hormone as AOD-9604 (Tyr-hGH177-191). The AOD-9604 page has the history of its official studies: six careful studies in people found no effect on IGF-1 or on how the body handles sugar, and did not establish efficacy for weight loss. Sharing the same chain is why the fat-loss claim travels with both names. It is not a second molecule with its own success in people. A research-chemical vial labeled 176-191 is not an approved drug. This site does not rank the names. Full records at /compounds/hgh-fragment-176-191 and /compounds/aod-9604.
