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. 
Although Cypionate stays in the system for much longer than a week this product gets injected on a weekly basis. Some athletes even prefer to take this substance twice a week. It is not unheard of for an athlete to take up to 1000mg of this product per week. Cypionate is one of the most powerful mass building drugs available. Large doses are not necessary but many guys have reported taking huge amounts of this drug per week. Cypionate is stacked well with Equipoise, Deca, Dianabol or Anapolon. This product would generally not be used pre-contest due to the excessive water retention and the long duration in the blood. Once taking this substance you can not manipulate it the same way you can do with Propionate and you are bound to look smooth if attempting to use it pre contest.
