I find it hard to believe that testosterone alone, which all those guys were (also) using, is allowing Froome to match the times of hardcore cocktail dopers like Armstrong et. al.
It doesn't. The new doping paradigm:
- use EPO microdosing or EPO precursor stimulants
-use CATABOLIC steroids (prednisone) in training (out of competition - legal) to aid recovery, train harder, loose weight faster and build power/weight ratio
- any other marginal gain not yet confirmed (Aicar type, etc)
Testosterone, nandrolone, etc and all bodybuilding steroids are ANABOLIC, ie they build muscle.
Asthma drugs and prednisone are CATABOLIC. Asthma drugs very specifically relax bronchial smooth muscle (and raise heart rate), prednisone reduces inflammatory pathways, and is MUCH MORE general and powerful in its effects. Prednisone may also have short term effects on blood parameters, eg haematocrit.
All three types have their specific places but should not be confused.
