luv2lift mentioned that addiction can come in many forms. I do not believe that testosterone is addictive, but a lifestyle can be addictive. Big-o-rexia or muscle dysmorphia comes to mind which is a psychological illness opposite of anorexia where a person feels they can never be big enough. It can happen to natural bodybuilders, but usually when on test, they feel the need to take more and more and more. It is more of a psychological illness though rather than an addiction.
I'm a sex object. When I ask women for sex, they object.
