Sophisticated dopers to be aware of testers

The battle to keep the London Olympics free from drugs has begun even before the opening ceremony next July.

GlaxoSmithKline (GSK), Britain's largest drugmaker, has offered a sophisticated laboratory that is ready and waiting.

From Reuters.com:

"We have a state-of-the-art facility, we have the best detection systems going, we're right up to date with the science, and if athletes know you've got good testing and good detection systems, it really has a deterrent effect," said David Cowan, head of the Drug Control Centre at King's College London and the man who will oversee London 2012's anti-doping regime.
His staff, which he has expanded to include eight times as many scientists as he would normally have, are aiming to conduct more than 5,000 tests at the London Olympics - roughly one for every two of the 10,000 or so athletes expected to take part.
As the science of detecting doping advances, athletes who cheat by using performance-enhancing drugs are devising ever more sophisticated doping regimes.

The drugs of choice for cheats, usually, vary from anabolic steroids to human growth hormone, blood boosters like erythropoietin (EPO), beta-blockers and stimulants, or diuretics.
