Research Overview
ACE-031
ACE-031 produced increases in lean mass in early studies, but development was curtailed after safety concerns and variable efficacy. Its literature remains important because it validated activin receptor blockade as a muscle-building strategy.
Human Insulin
Human and animal studies show insulin powerfully suppresses whole-body and muscle protein breakdown while increasing amino acid uptake and glycogen storage. It is widely established in clinical nutrition and endocrinology, with anabolic effects on muscle being secondary to its anti-catabolic action.
