(CBSNews.com) - Alex Rodriguez says he has never used performance-enhancing drugs in the 10 years he's played for the Yankees. The man at the center of the case is Anthony Bosch, who ran a Miami clinic that provided drugs to 14 Major League Baseball players. Bosch testified, behind closed doors, in Rodriguez' appeal hearing. But on Sunday night, Bosch spoke publicly for the first time on "60 Minutes."
Asked what were the various banned substances he was taking once Alex Rodriquez was fully into Tony Bosch's protocol, Bosch said, "Testosterone, insulin growth factor 1, human growth hormone, and some different forms of peptides."
Bosch said all of the substances were banned.
Bosch told CBS News that over two years he gave Rodriguez six banned drugs. He says sometimes he administered them himself and often he delivered them to Rodriguez's homes and hotels. "Most of the times that we were together was after hours, was probably between midnight and 7:00 a.m. in the morning," Bosch said.
Asked what they were doing between midnight and 7:00 a.m., Bosch replied, "Less people, less eyes."
In Bosch's records, CBS News found a text from June 11, 2012. The Yankees were in Atlanta. Bosch, en route to a hotel, wrote, "Just landed. Heading your way." The reply from a phone linked to Rodriguez said, "Try to use service elevators. Careful. Tons of eyes."
Bosch said, "I had to disguise myself or wear sunglasses at night or take an elevator, a freight elevator instead of the normal elevator. And it was challenging."
Bosch told CBS News he prepared testosterone three ways -- in an injection, in a lozenge called a troche, and in a cream. Bosch says the troche had to be taken early in a game so the testosterone would dissipate before any post-game test. The low-dose cream was a booster.
If a game goes into extra innings, Bosch said, "Out comes the cream. ... And if you had a troche in the fifth inning, we'd all be in trouble."
Bosch told CBS News that he timed the doses so precisely that they never showed up in baseball's tests. Rodriguez passed 12 tests during the time in question, Rodriguez says, because he's clean. Bosch was cited for practicing medicine without a license and fined $5,000. A grand jury is meeting in Miami to decide whether anyone in the case should face criminal charges.
