EPO was developed to increase athletic performance speed, endurance, strength, etc. It does this by elevating the red blood cell count in the body. The results from increasing the oxygen in the blood are fantastic in the areas of increased body weight, exercise capacity, respiration body metabolism and energy efficiency. EPO is easy to take (one injection a day for 14 days or so) and lasts a long time (three to six months). EPO may raise your blood pressure, so keeping an eye on it is recommended.
