Muscle Growth Supplement Linked with Liver Failure

On December 23, 2013, the FDA advised consumers to immediately stop using muscle growth supplement Mass Destruction (by Blunt Force Nutrition) because it is labeled as containing at least one synthetic anabolic steroid and has been linked to at least one reported case of liver failure.

Use of anabolic steroids and steroid-like substances is associated with liver injury and other serious side-effects, including changes in blood lipid levels, increased risk of heart attack and stroke, shrinkage of the testicles, breast enlargement and infertility in males, masculinization of women, and short stature in children.

Mass Destruction is sold online and in some retail stores and fitness gyms.

(See's Review of Muscle Enhancers for tests of related products.)

Consumers who have purchased this supplement should discontinue use immediately and contact their healthcare provider if they have experienced any adverse side effects. Consumers and healthcare providers are also encouraged to report any adverse reactions to the FDA's MedWatch Adverse Event Reporting Program.
