The derivatives of testosterone’s are called anabolics. This is when a testosterone is changed in a way that only keeps some of its original characteristics buts excludes others. For example a anabolic steroid could have muscle building effects but without the water retention of the original testosterone it got derived from. These variations are endless and a science on its own. We will discuss and explain every characteristic of every anabolic steroid in depth so that athletes would know what is best for them because we all have different needs.
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.
