Over 120 people were arrested in an 18-month international investigation of illicit steroid labs, the Drug Enforcement Administration announced Monday.
The DEA said the wide-ranging probe dubbed Operation Raw Deal was assisted by foreign governments in nine countries including China and led to the seizure of 56 laboratories for manufacturing anabolic steroids and human growth hormone.
DEA spokesman Michael Sanders said 143 federal search warrants were issued during the probe, many of them since last Thursday.
The number of steroid doses seized in the raids amounted to 11.4 million.
Investigators seized over 500 pounds of raw powder originating in China and used to manufacture steroids.
News conferences by law enforcement officials were planned for San Diego, New York City, Houston, Kansas City and Providence, R.I., said Sanders.
In addition to China's cooperation, other countries participating in the investigation were Mexico, Canada, Australia, Belgium, Denmark, Germany, Sweden and Thailand.
