They Can't catch EPO or HGH, two of the more common PED's today. Victor Conte, Mr. Juice himself, has said that urine testing cant do the trick.
The thing boxing need is one governing body. How many time do we have to have the same dumb poll. No one who love the sport is against testing. But throwing up blood testing doesn't resolve **** without one governing body to oversee, set guideline, and enforce the test. The question isn't about blood testing it is how should it be done. People throw around OSDT without realizing what this means. For one it ain't free. Another it is year round. You have to report where you are at all the time so you can be tested at their discretion. Throw that in with adequate facility is availible in 3rd world country. So am I for better testing? Absolutely. For only select fights? Hell no. All or none.
Considering one of his clients. Shane Mosley, had used EPO and the Clear and the Cream and NEVER failed a urine test should tell you something.
