Race Radio said:It was not a "French investigator" It was a French journalist. He wrote that the drugs are not banned "Per se" which is "by themselves/itself". Used as part of transfusion program they are a banned product.
It was a "source close to the investigation" that is the source of most of this story.
You may question if something works or not, but it is a fact that WADA sees some hypertension drugs as doping products and has banned them.
Oh, I'm not questioning whether or not Beta Blockers work as a performance enhancer. They don't. period. They serve to slow the both the average and max heart rate - a small dose can cap one's max heart rate at 20% below it's norm. There's no way in which that could be considered performance enhancing.
Now, whether they serve to mask a performance enhancing drug or reduce a negative side effect of such a drug, that's another question.
