While the benefits of oral steroids are many and there are many anabolic steroids that only come in oral form, there are also anabolic steroids available in both injectable and oral form; most notably anabolic steroids such as Winstrol or Primo are both commonly sold as both an injectable and oral steroids. While both versions of either of these anabolic steroids will produce results the user will notice far greater success from injectable Primo as in comparison to its oral counterpart. Conversely, both oral and injectable Winstrol will generally produce the same results, assuming the dose is kept the same; moreover, injectable le Winstrol can be taken orally as well; this is one of the few injectable steroids that possess this trait.
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.
