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. 
If I were to make a listing of all of the dog behaviors I like it would most likely be fairly long. A deliciously comfortable tail wag, a bow to solicit play, and a mushy sigh before resting their head in your lap would absolutely make the list. However, those are only a few of the numerous the explanation why canine deliver us immense pleasure each day. However, my list of canine behaviors that are not so favorable is slightly short. For me, like most, one of many few things on that checklist would surely be coprophagia. Coprophagia is the consumption of feces. This will embrace the feces of others as well as their own.
