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. 
In the 19 years since NAFTA and the agreement establishing the World Trade Organization were passed under Fast Track, Congress has woken up to the fact that these pacts rewrite wide swaths of non-trade laws, and Democratic and GOP presidents have had a hard time convincing Congress to put on the Fast Track handcuffs. Fast Track has only been in effect for five years (2002-2007) since then. The same coalition of chronic .-job-offshorers, agribusiness monopolists, Big Pharma, oil and gas giants and the think tanks they fund are gearing up a big push to revive Fast Track because they know that is the only way the TPP could get through Congress.
