Another story of guys being just too open with steroid sales , when will people learn that steroids are not a joke?

Police arrested more than 60 people – including a former NYPD officer and a professional boxer – in a sweeping steroid sting at two Queens gyms that acted like “drug supermarkets,” officials said Friday.

Gym owners and trainers allegedly sold human growth hormone and other steroids brazenly at the front desk, on the gym floor and in locker rooms, said Police Commissioner Raymond Kelly.

The sting also netted two guns, more than an ounce of cocaine, numerous prescription pain killers and more nearly $40,000 in cash, Kelly said.

The Powerhouse Gym in Bayside and Envy Us in College Point allegedly made as much as $50,000 a week from the illegal drug sales.

“These gyms had in reality been turned into drug supermarkets,” said Queens District Attorney Richard Brown.

Ninth-ranked junior lightweight boxer Cindy “Checkmate” Serrano, 25, was one of those arrested. She was charged with criminal sale of a controlled substance, but there was no evidence that she was using the steroids, Kelly said.

Former New York Police Department officer, Benigno Mercado, was also charged with selling drugs. Mercado was fired last year when he was caught with stolen license plates on his car while on suspension for another matter, Kelly said.
