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. 
This is the second time Jones has tested positive for using banned performance-enhancing drugs. The 30-year-old was scheduled for a bout with Cormier at UFC 200 in July 2016, but tested positive for two banned substances , clomiphene and letrozol, and was banned for one year . That failed test came just three days before the event, leading to him being pulled from the fight. According to TMZ, Jones could face up to a 4-year ban as a multiple-time offender. Testing positive for Turinabol carries up to a 2-year suspension from the USADA for first-time offenders, according to MMA Fighting.
