That is the sad thing about this whole controvery. The funny thing is that, there are no experts who are really talking. Most of the so called officials have some type of agenda. Do not think that someone who dislikes or is jealous of the quality of the US track team is not jumping up and down. And then there are the cynics who spend most of their days accusing everyone of drugs.
Drug use is rampant in all sports.
Sports who have drug testing still get hammered because there is not testing for all drugs being use. I tell you here, if somenut told an athlete that inhaling skunk dung would give you ten percent better performance, some idiot would have his or her athlete use it. Look at creatine. While some use it with no present problems, there are several athletes out there who will never be the same due to the severe dehydration that comes from not hydrating oneself while using creatine. Usage of this drug is everywhere.
