The FDA issues a warning against the use of SARMs


The FDA has issued a release today in relation to selective androgen receptor modulators, better known as SARMs, typically promoted to help users build muscle. It’s essentially a warning against the use of bodybuilding and sports supplements containing those types ingredients, a couple of examples being Ostarine and Andarine.

In the release from the FDA, the agency says that while there are SARMs products out there marketed as dietary supplements, they are not dietary supplements, and are actually considered unapproved drugs. It warns against the use of the products saying that life-threatening reactions have occurred including liver toxicity.

The FDA also mentions that SARMs also have the potential “to increase the risk of heart attack and stroke, and the long-term effects on the body are unknown.” You can read the main exert from the FDA’s release below or check out the entire story on the agency’s website at

“We are extremely concerned about unscrupulous companies marketing body-building products with potentially dangerous ingredients. Body-building products that contain selective androgen receptor modulators, or SARMs, have not been approved by the FDA and are associated with serious safety concerns, including potential to increase the risk of heart attack or stroke and life threatening reactions like liver damage,” said Donald D. Ashley, J.D., director of the Office of Compliance in the FDA’s Center for Drug Evaluation and Research.”
