Research & Clinical Studies

Structure-Activity Relationship Studies
Systematic truncation studies of the hGH molecule identified the 176-191 region as sufficient for lipolytic bioactivity in adipocyte assays. The fragment showed no somatogenic or diabetogenic activity.

AOD-9604 Clinical Development
AOD-9604, a modified form of HGH Fragment 176-191, progressed through phase 2 clinical trials and received GRAS designation from the US FDA in 2014.
