The Food and Drug Administration has sent a letter to companies that manufacture, market, and distribute products containing androstenedione, or "andro," which acts like a steroid once it is metabolized by the body, and therefore, can pose similar kinds of health risks as steroids. These products are generally advertised as dietary supplements that enhance athletic performance based on their claimed anabolic and androgenic properties to stimulate muscle growth and increase production of testosterone.
FDA has sent warning letters to 23 companies asking them to cease distributing products sold as dietary supplements that contain androstenedione and warning them that they could face enforcement actions if they do not take appropriate actions.
