The case was referred from the San Mateo County District Attorney's Office for federal prosecution because Mr. Mosdromos is alleged to have sold and shipped the illegal drugs throughout the country and internationally.
His alleged activities were first discovered on April 23, after Department of Homeland Security Investigations intercepted a package containing steroids at a United Parcel Service store.
The drugs from China were addressed to his postal box at the UPS store located at 325 Sharon Park Drive in Menlo Park. A second shipment containing thousands of Xanax pills from the United Kingdom was intercepted on May 18, according to the criminal complaint filed in U.S. District Court for Northern California.
In June, Mr. Mosdromos' Loma Verde Avenue residence and his business, One 2 One Fitness in Menlo Park, were searched by the Menlo Park Police Department and Homeland Security, assisted by the FBI.
Law enforcement found gallons of steroids, a conversion lab to turn pills into liquid, thousands of prescription pills MDMA (Ecstasy) and other controlled substances, along with shipping labels addressed to locations across the United States and to many overseas countries. He was arrested and posted bail.
He initially denied owning the illegal substances, but he later admitted he had been selling prescription medications and manufacturing anabolic steroids, according to the complaint.
Mr. Mosdromos told police that he trafficked the drugs to make extra money so that he could help pay for his mother's medical expenses. A $3,000 investment of raw product could be turned into $30,000, he allegedly said.
"He said the operation is much bigger than he, but he did not disclose any co-conspirators or elaborate on how the operation works," according to the complaint. He denied the Xanax shipment was destined for him, an investigator wrote.
According to the federal complaint, an FBI officer had intercepted an incoming text message on Mr. Mosdromos' cell phone from someone wanting to purchase anabolic steroids. The buyer came to Mr. Mosdromos' residence to purchase the steroids and admitted to officers that he had previously purchased 500 tablets of the steroid Anavar for $150 and previously purchased injectable testosterone from Mr. Mosdromos.
Mr. Mosdromos waived his Miranda rights on June 7 and told investigators that his fiancee and employees did not know that he traffics and manufactures controlled substances. He told his fiancee the shipments were supplements, according to the report.
He allegedly told investigators that the prescription medications found in his apartment were shipped from countries including China, the United Kingdom, Pakistan, India and Mexico. He shipped the medications to various people after receiving instructions from buyers.
Mr. Mosdromos was booked into San Mateo County Jail in June and posted $25,000 bail, but on Friday, Aug. 31, in the San Francisco federal court he was again taken into custody, according to court documents. He faces charges of possession with intent to distribute a controlled substance and conspiracy to possess with intent to distribute a controlled substance. If convicted, he could receive maximum penalties of 20 years in prison and a $1 million fine.
