The problem is, people believe that the composite entity, human nature, of which behavior is one part, is governed by immutable laws. Much like the belief that the social world is governed by immutable laws, precluding the acting upon it by individuals, people fail to act upon themselves because, likewise, they believe their natures to be governed by similarly immutable laws, largely as a result of the successful indoctrination of the masses of determinist theories which, because of their effectiveness in providing a vehicle for what is the true function of government (namely, to control people), are understandably a integral part of the orthodox weltanschauung. This inculcates a fatalistic attitude that begets the very problem that supposedly is occasioned by this taken for granted knowledge of our own powerlessness.
Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes.
