At the end of 2005, a German drug surveillance authority confiscated nutritional supplements (effervescent tablets) from a German manufacturer, which contained among other steroids high amounts of metandienone (about 15 mg/tablet) and stanozolol (about 17 mg/tablet). These anabolic steroids were not declared on the labels. Additionally the drug surveillance authority confiscated other nutritional supplements like vitamin C -, multivitamin -, calcium - and magnesium – tablets, which were produced from the same manufacturer on the same production line within the same time interval. The LC/MS/MS analyses showed cross-contaminations of the vitamin C -, multivitamin - and magnesium-tablets with metandienone and stanozolol. These cross-contaminated products were produced for the sale in ordinary German and Spanish groceries and drug stores. Verf.-Referat
