Anabolic steroids are, unfortunately, used by many athletes and body builders to enhance their muscularity and strength. In professional sports their use is illegal. But they are legal in pro body building.
I am now hearing in the wind that 30 minutes a week of exercise is too time consuming. I find this hard to believe but hey, some people have full time jobs, 47 kids, second jobs, pets, lawns, nails to polish, cigars to smoke, etc.
