Fast forward to 2009. Lance's OFF-score was 95.9, when he finished third in 2009. The ups and downs of his blood values in July are another question, but the sport looks overall significantly cleaner by this metric.
That doesn't discount the likelyhood Armstrong was using other PEDs in his comeback. The
steroidal module of the ABP wasn't implemented until 2014, and the HGH module was just implemented last year. As long as he didn't breach the 4-1 T/E ratio, his samples wouldn't have been tested for synthetic testosterone (only the expensive CIR test is used, which can distinguish between a synthetic testosterone molecule & a naturally produced molecule, when an athlete breaches the 4-1 T/E ratio).
Furthermore, Armstrong has a history of using test & HGH. In his presentation yrs ago where he was a guest speaker at a Colorado University sports ethics class, he admitted using test & corticosteroids early in his career (including the 1993 WC) pre-EPO usage (this was his infamous characterization of
"low-octane" doping. Lol).
With Armstrong being 38 yrs old in his comeback, he would have greatly benefited from testosterone & HGH - both very powerful hormones (testosterone levels start declining, on average, about ~1% per year after age 30). Plus synthetic testosterone induces some
erythrocytosis (guys using TRT under a physician's care will have to have their Hct checked a couple of times a year to avoid increasing higher levels which can cause clotting).
So, who knows if he blood doped or not for the 09 Tour, but in my opinion there's no way he's going to finish 3rd on the podium at his age
clean.
