Research Overview

Epoetin Alfa

Human studies in anemia and performance-related settings show that increasing red-cell mass can improve aerobic capacity and endurance. It remains heavily regulated because excessive erythropoiesis raises thrombotic and cardiovascular risk.

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.
