Merckx index said:
So he was taking EPO at least four years before cancer. I'm not surprised, but this deepens the mystery of how he became such a good climber, and a better TTer, after cancer. RR and some others think he was a high responder, and it does appear he has a naturally low HT that would have allowed him to get a larger benefit from EPO than many other riders.
But why did the benefit not really become apparent until after cancer? If being a high responder is what enabled him to win all those Tours, why could he do nothing in GC in four tries before cancer? Other alleged high responders, like Ulle and Pantani, seemed to reach their GC potential much sooner. Even Riis was a better climber than Armstrong at that time.
Was it Ferrari? Maybe, but I find it hard to believe that Ferrari + EPO made a bigger difference in his GC performance over EPO alone than EPO alone did over no EPO. All EPO seemingly did for him is make him a much better one day racer. For four years. Then boom, suddenly he can climb, not just better, but he goes from a total non-climber to the best in the world. Was Ferrari's program really that good?
Excellent post with many pertinent questions. Here are my thoughts on the subject-
Pre-cancer, Armstrong was probably taking mass quantities of cortisone, testosterone and HgH, moreso in relation to the EPO. You can tell from his physique and his then-modest goal of being a good one-day, short stage racer.
When he came back in 1998, his ambitions changed along with his training and doping regimens. Ferrari probably got him on a plan where he used testosterone for recovery as opposed to recovery AND muscle building.
When used as recovery agents, you can go very light on the HGH and testosterone and still get results, but the results are going to be different than if you are hitting these products hard.
From what I understand Armstrong may have quit using HgH post-cancer, but no one really knows for sure because he hasn't stopped lying about anything even after he got busted.
The other thing about Ferrari was the exclusivity clause he had with Armstrong. The good doctore was not allowed to service any other riders who were gunning for the Tour, so who else got to benefit from his expertise in the peloton for the Tour? No one. And this wasn't just for the Tour. Ferrari wasn't treating any of Armstrong's Tour rivals in any other races from what I can tell. They all had to go elsewhere. And as we have seen, if Ferrari was the # 1 doping guru, whoever was #2 was a sad second indeed.
