Court documents allege that Joel Pasternak ordered and received anabolic steroid powders shipped directly from China in misbranded packaging, delivered by the USPS. The packages were identified as hair bleach, wall painting additives and cosmetics, but in reality contained raw anabolic steroids. Joel Pasternak operated five clandestine labs where the raw steroids were mixed with other substances and repackaged in vials, posters and tablets for consumption. He marketed the products to those outside of the East Tennessee area, shipping the products by mail. Online consumers were paying via Western Union and MoneyGram.
