A Florida man, who authorities said was making $1 million a year distributing drugs on Long Island and in New York City, pleaded guilty Thursday in federal court in Central Islip to conspiracy to illegally distribute steroids and distributing steroids, according to officials.

When Gregory Kovar, 48, of Miami Beach, was arrested last June, authorities also charged him with distributing oxycodone and cocaine. But as part of a plea bargain, those charges were dropped, according to officials. Under federal guidelines, Kovar could face from 121 to 151 months in prison at sentencing.

At the time of Kovar's arrest, federal prosecutor Burton Ryan said Kovar was "a career drug dealer," who had originally lived in College Point. Kovar moved to Florida in 2007 after serving about 90 days in prison for distribution of steroids in Queens, Ryan said.

Kovar's ring operated a number of "laboratories" in New York and Miami in which chemicals were imported from overseas, blended with other chemicals, and the resulting mixture poured into vials, Ryan has said. On the vials were counterfeit labels of actual steroids.

"Some were counterfeit, some adulterated, and some were fake," the indictment said of the steroids. None of the chemicals were approved for sale in the United States, the indictment said.

Kovar made a brief statement to federal Magistrate William Wall acknowledging his crimes. Kovar's attorney, Rick Haley, of Islandia, declined to comment, as did Ryan, an Eastern District assistant U.S. attorney.
