Anabolic steroids differ in their characteristics, which means there are steroids that are only suitable for specific uses. For instance, Trenbolone is not recommended for bulking but it is an outstanding fat burner. This makes it perfect for a lean mass cycle or a cutting cycle. Always take the side effects of a particular compound into consideration whenever you plan a stack. Do not combine anabolic steroids that show similar side effects. For example, never combine Anapolon and Dianabol because they are already quite toxic and if you combine them, the toxicity will increase exponentially and cause serious damage to your body.
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. 
While a fantastic steroid for enhancing athletic performance, the vast majority who supplement will do so for physique related purposes, and to enjoy such benefits it's normally best to already be a little lean. The hardening and physique enhancing traits will not shine through a layer of body-fat, and this means use will normally be best towards the latter half of a diet. Of course, by its nature, Winstrol will actually help you lose some of the fat you're holding onto; in-fact, it's sometimes prescribed for those who suffer from obesity due to hormonal imbalances. Beyond obesity, Winstrol is also used to treat anemia, angioedema and conditions where severe strength loss may have occurred; truly a fantastic steroid.
