In context

AOD-9604 is a fragment of human growth hormone developed specifically as an obesity drug. Unlike most peptides sold online, it was tested properly: pooled data across trials covering more than 900 participants found no statistically significant difference in fat mass or body weight against placebo. Development was terminated for lack of efficacy. It is still marketed for fat loss.

AOD-9604 is not approved. Legal status differs by country — see the regulation section or the jurisdiction pages.
