Travis Tygart, chief executive of the United States Anti-Doping Agency, said a blood test can allow testers to detect use of energy-boosting synthetic EPO, human growth hormone and "a number of potent performance-enhancers not detectable in urine. . . . With a [30-day] window like that, you could dope to the gills and get away with it."

Travis Tygart, executive director of the USADA, said he had talked to representatives of both fighters about providing testing. Tygart said he welcomed the request as he would for any sport that does not have stringent Olympic-type testing.
"I think every sport that wants to have clean athletes it's a sign of a step forward to have out of competition testing," Tygart said. "It's an essential thing to do if you want to protect the integrity of the sport. Clean athletes want a level playing field."
Tygart noted Olympic athletes are tested often and without notice. He said less than a teaspoon of blood is removed out of an average of 380 teaspoons in the normal human and that it regenerates within an hour of being withdrawn. Blood tests, he said, can find things urine tests cannot, like the use of human growth hormone, synthetic hemoglobin or blood transfusions, all of which "certainly would aid in an endurance-type event".

Travis Tygart, the chief executive of Usada, said his organization has a checklist that it calls the matrix of effectiveness. It includes blood and urine testing, both in and out of competition. Blood tests, Tygart added, detect prohibited substances like human growth hormone, synthetic hemoglobin, designer EPO and blood transfusions, while urine tests do not.
Pacquiao has agreed to have his blood tested three times: in early January, when the fight was expected to be announced, 30 days before the fight and immediately after it. He also agreed to random urine testing.
But Tygart said the 30-day window would still allow an athlete plenty of time to dope with illegal substances not detectable by urine testing.
“That kind of window is totally unacceptable,” Tygart said. “It would provide a huge loophole for a cheater to step through and get away with cheating.”

Manny only agreed to 24 days because of the Hatton 24/7 video,
but from that fight it's clear that Manny can go on the juice for 24 days and still be as effective as when he gets to juice for 30 days.
