2. Abnormal Development of Upper Body Muscles
Due to the reason that upper body muscles have more androgen receptors, steroid users often grow an abnormally big upper body. On the other hand, lower body muscles have fewer androgen receptors, and so grow at a slower rate.
Of course, all muscles get bigger, but they don’t grow at the same rate, so it may result in a large upper body. But don’t believe that if a person has small legs, he or she is definitely using steroids; DNA and a proper training routine also play an important role.
