EPO (Erythropoietin) is a Blood Oxygenation Drug to improve endurance
Buying Epo provides better endurance. This is one of the requirements of successful bodybuilding and athletics. Part of the reason why athletes and other sportsmen spend hours in the gym pumping iron, or on the track and field doing strenuous exercise, is to increase their endurance capacity. With the entry of Erythropoietin, all this changed. Using synthetic EPO, athletes can increase performance significantly by ensuring their blood has sufficient oxygen levels.
