Selective Androgen Receptor Modulators (SARMs) are a class of therapeutic compounds that have similar properties to anabolic steroids, but with reduced androgenic properties. This property allows SARMs the advantage of androgen-receptor specificity, tissue selectivity, and the lack of steroid-related side effects. Some potential side effects of anabolic steroid use include acne, liver damage, breast tissue development, and shrinking of the testicle in males, and deepening of the voice, growth of hair on the face, stomach, upper back, and abnormal menstrual cycles in females.
