Long term positive effects of doping.

Depends on the DNA. Look at these examples.
Keith Richards alive and smiling
Neil Young not so healthy
Warran Zevon dead died of cancer
David Bowie wealthy healthy married to a beautiful woman
Fignon dying of cancer
Eric Clapton running on all cylinders
Lance Armstrong fifth child on way TdF 3rd last year, second in tour de suisse

Like the evil sports doctors who prescribe these drugs are actually looking at genetics and its effects.
