Research Overview
Darbepoetin Alfa
Clinical studies show durable hemoglobin correction with less frequent dosing than epoetin alfa. The endurance benefit, where present, would come from improved oxygen-carrying capacity rather than a direct ergogenic pathway.
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.
