A 10-month investigation culminated in the arrests of three people this week when an anabolic steroid manufacturing ring was busted in El Dorado and Sacramento counties.

“In terms of underground steroid labs, this was a huge seizure for this area,” Gordon Taylor, DEA assistant special agent in charge, said in a statement. “The illegal use of anabolic steroids can be a dangerous practice, especially for young people. This danger is only compounded when drug rings manufacture steroids in unsanitary, unsterilized underground labs like we found in this case.”

Agents seized a large anabolic steroid lab in Elverta, more than 500 vials and 1,850 capsules of anabolic steroid pills. Arrested were Jason Glavin, 37, of El Dorado Hills, Erin O’Neil, 40, and his wife Amy O’Neil, 32, both of Fair Oaks.

The investigation was a team effort between the DEA Sacramento District Office and West El Dorado Narcotics Enforcement Team (WENET), with assistance from the California Highway Patrol. The El Dorado County District Attorney’s Office is prosecuting this case.
