UCI spokesman Enrico Carpani said Landis requested the "B" sample, which is not required by cycling's governing body.
"We are confident in the first (test)," Carpani said. "For us, the first one is already good."
--Result of test(A) alone is solid as an evidence without test(B) assuming it was done properly.--

Testosterone can build muscle and improve recovery time when used over a period of several weeks, said Dr. Gary Wadler, a member of the World Anti-Doping Agency and a spokesman for the American College of Sports Medicine. But if Landis had been a user, his earlier urine tests during the tour would have been affected, he said.
"So something's missing here," Wadler said. "It just doesn't add up."
--This makes a good sense.--
Landis's part:
He didn't respond quick enough, keeping silence for too long, made many people think "Aha, He did it!" It gave an impression that he was thinking, "Ok, I got caught. Now, what I'm going to do?" He should be angry and speaking out immediately like hell at the announcement of test result, like Lance has been doing. Why he didn't come out soon and defend himself? Isn't it the way normally people react when he or she was accused of being a cheater?
