You also get blood doping which is used to increase endurance. This is where someone has a load of blood taken out of their system, then stored away. In the meantime their body reproduces this blood to get them back to a normal level. Then they re-inject the blood, meaning they have increased the amount of oxygen rich blood in their system.
Even Defoe is on this blood spinning ting.
