Lance Armstrong returning to the Tour next year

can use your own blood for blood doping and keep the heamatocrit below 50. use testosterone patches on scrotum for short time 1-2hr post race and remove, so drops to normal by morning. numerous masking agents.

I thought they already had a method of autologous blood doping but apparently not.. but they are working on it and its introduction will be kept secret, much like the EPOv3 tests I guess..
