Research Overview
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.
Meldonium
Clinical literature focuses on cardiometabolic support and exercise tolerance rather than direct anabolic effects. Any endurance benefit is thought to come from altered substrate handling and improved tolerance to stress.
