The 40-year-old, who quit the sport in 2007, said in a television interview that he used erythropoietin, blood transfusions and cortisone to boost his performance while riding for Rabobank.
"The period I used banned substances was from 1997 to 2007, the end of my career," Boogerd, who was fifth in the 1998 Tour de France, told national broadcaster NOS.
"I'm sorry I kept the (doping) culture alive," he said. "I'm sorry I never put up my hand and publicly said: 'This can't go on. It's not good.' And I'm sorry I wasn't riding in another era.
"I flew to Vienna for blood transfusions. I stored my own blood for later use."
Boogerd, who won the Amstel Gold classic in 1999 and claimed two stage wins on the Tour de France, refused to implicate anyone else in his confession.
"I'm not naming people," he said. "It was my responsibility, my choice."
The three-times Dutch champion becomes the eighth rider of the now defunct Rababank team to admit to doping.
