McGwire first became eligible for Hall of Fame voting in 2007. For election, a player needs to be listed on 75% of ballots cast; falling under 5% removes a player from future consideration. Between 2007 and 2010 McGwire's performance held steady, receiving 128 votes (%) in 2007 , 128 votes (%) in 2008 , 118 votes (%) in 2009 , and 128 votes (%) in 2010 . The subsequent ballot in 2011 showed the first sub-20% total of 115 votes (%), and McGwire's total votes continued to decline (112 votes (%) in 2012 , 96 votes (%) in 2013 , 63 votes (%) in 2014 , and 55 votes (%) in 2015 ) until he was finally eliminated after receiving only 54 votes (%) in 2016 . 
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.
