MuscleMaster.com, Inc. is conducting a voluntary nationwide recall of all lots and expiration dates of 17 dietary supplements sold between June 1 and November 17, 2009.

FDA informed MuscleMaster.com that it believes the recalled products contain ingredients that are steroids. Specifically, FDA advised MuscleMaster.com of its concern that the Recalled Products may contain the following ingredients that are currently classified, or the FDA believes should be classified, as steroids: "Superdrol," "Madol," "Tren," "Androstenedione," and/or "Turinabol."

While MuscleMaster.com cannot independently confirm FDA's concerns, that any one or more of the recalled products in fact contain these ingredients, MuscleMaster.com is undertaking this voluntary recall out of an abundance of caution and in deference to FDA’s stated concerns.

Acute liver injury is known to be a possible harmful effect of using steroid-containing products. In addition, steroids may cause other serious long-term adverse health consequences in men, women, and children. These include shrinkage of the testes and male infertility, masculinization of women, breast enlargement in males, short stature in children, a higher predilection to misuse other drugs and alcohol, adverse effects on blood lipid levels, and increased risk of heart attack, stroke, and death.
