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. 
In some cases, bodybuilders and athletes may choose to use Winstrol for a short time without using any other compounds. This can increase the risk of some side effects while decreasing the risk of others. For example, failing to use testosterone alongside your Winstrol may lead to some unwanted side effects associated with low testosterone, such as fatigue or a lowered libido. However, if you choose to forego testosterone, there’s no need to add an AI to your stack, which can make things simpler and save you money. You should be sure to weigh the benefits of using a Winstrol cycle with stacks and the risks of running a Winstrol-only cycle before you make a decision.
