A Staten Island “anti-aging” doctor charged with writing hundreds of illegal steroid prescriptions halted his two-week trial yesterday to plead guilty to a lesser charge and end his medical career.

Dr. Richard Lucente, 38, who faced 76 counts of illegal steroid sale, confessed to one count of accepting kickbacks from Lowen’s Drug Store in Bay Ridge, Brooklyn, where he steered patients, including city cops. He must forfeit his medical license.
