The two compounds engage GH biology from opposite directions: AOD-9604 is downstream of GH release a fragment that retains specific GH biological activity (lipolysis) without engaging GH receptors Tesamorelin is upstream of GH release a GHRH analog that prompts the pituitary to release endogenous GH Origin Comparison This is a fundamental distinction
