Direct supplementation of synthetic testosterone via drugs is also possible, but there are a multitude of dangers associated with this option. A 2014 study revealed heart attack rates increase in men above 65 who took testosterone. Therefore, individuals with histories of cardiovascular problems should take great caution in using this method. Another danger is that increasing the body’s testosterone levels to concentrations above the normal range can increase the rate at which testosterone is converted to estrogen. Many detrimental and feminizing effects can occur if this becomes the case.
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.
