Why Doping is Banned
During transfusion tainted blood can be put back into the body, and often the people transfusing the blood aren’t trained doctors. Putting tainted blood into your body or letting your friend transfuse your blood rank pretty high on the list of best ways to make it to the emergency room.

The EPO method is no better. Once the percentage of red blood cells rises above 50 percent, the blood becomes thick and viscous like molasses. This can lead to a heart attack or stroke. In fact, after EPO was developed in the late 1980s, 20 European endurance athletes died in a span of 4 years, and most experts suspect that they died of heart failure due to thick blood.
