Anders Breivik , known as Norway’s “laughing gunman,” killed 77 people, many of them children, in 2011. Norway officials amassed pages and pages of analysis of the horrific crime, but almost nobody noticed that the smirking Breivik was taking large quantities of mind-altering chemicals, the Daily Mail reported . In this case, the substances are an anabolic steroid called stanozolol, combined with an amphetamine-like drug called ephedrine, plus caffeine. The authorities and most of the media were more interested in his non-existent belief in fundamentalist Christianity, the Mail reported.
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.
