3 Tours de France my dear fellow. I think that is pretty conclusive evidence.
Fignon took amphetamines, something Anquetil, Coppi, Simpson,Merckx and many other top riders could not live without. He also took steroids that helped tremendously in a 3 week race (Lemond words) and Superman could still beat him?
How did he know the effects of testosterone anyway?
Amphetamines

Apart from the limited benefits of amphetamines, they were a non-factor in the Tour during the 80s because they were detectable in anti-doping.
This is real simple:
Willy Voet, the guy at the centre of the whole Festina affair said Charly Mottet rode clean and he was ranked World number 1 in 89. He also finished 4th in the Tour twice and 6th in 89. He won Dauphine Libere 3 times and numerous other big races.
Voet also said that Eric Caritoux won the Vuelta in 84 clean but doped at other times.
The Helvetia team of Paul Koechli had a reputation as a non-doping. no needle team. Steve Bauer, team leader at Koechli' team's in 88-89 who was another rider with a clean reputation finished 4th in the 88 Tour.
Another Koechli rider Giles Delion who was a clean rider and spoke openly about doping long before Festina, finished 16th in his Tour debut at 23years old and won the Tour of Lombardy the same year, 3rd at Milan-San Remo, Tirreno-Adriatico, 2nd Romandy, 5th in the World Cup.
Jesper Skibby who admitted to doping from 91 onwards which included his biggest victories, finished 3rd in the first long TT in the 87 Tour on his Tour debut. Skibby won a stage at the Giro in 89 and finished 14th overall.
Rolf Jarmann, another rider who admitted to doping from when he joined the Ariostea team in 92 won a stage at the Giro in 89. Swiss Champion in 90.
Andy Hampsten, another guy with a clean rep, 4th in 86 Tour and Giro winner in 88, 3rd in 89.
If these results are genuine, that means they were achieved against doped up riders on amphetamines, testosterone, cortisone etc. If this was possible I fail to see how a supposedly more talented athlete like LeMond could not win the Tour clean.
You quote Fignon as a reference but if you believe Fignon then you would also have to believe what the likes of Voet, Delion, Skibby etc say or does what Fignon published in his book have more value than what others have stated in their publications other than if suits your own particular agenda.
