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. 
you sure your not a farmer Jamie N Rocky Pearson, because everything you said was true. And thank you for standing up for us dairy farmers for a change. I am actually a dairy farmer from Northern Ireland and its very dishartening hearing what some people say about my proffesion when all they have done was cherry pick data from the internet. I belive that a balanced diet is best, manly unprocessed food. but just for a giggle lets say cow meat/milk was bad, what would happen to the cows, no market for them they wouldnt exist, which would be a crime in of itself not to have them in the feilds.
