Research Overview
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.
Methoxy PEG-Epoetin Beta
Clinical trials show predictable hemoglobin correction with a long dosing interval and sustained red-cell stimulation. Any VO2 max effect would be secondary to higher hemoglobin, not a direct ergogenic mechanism.
