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. 
Which made Canseco’s second benefactor — Mike Wallace — all the more important. John Hamlin, a producer at 60 Minutes , had gotten a tip about Canseco’s book from a friend at another network. (The friend couldn’t act on it because his employer was a Major League Baseball rights holder.) Hamlin began calling baseball people and confirming the details. Almost no one would talk on the record, but they suggested that Canseco’s account was true. One of the few allegations Hamlin couldn’t verify was Canseco’s insistence that Roger Clemens was juicing.
