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. 
The one agonizing aspect of the Belmont is the mystery surrounding Big Brown's performance. We've heard many theories, and that is what they will remain. No one will ever know for sure why a horse that personified perfection suddenly came apart at the seams. Was it the deep track, the stifling heat, getting rank early in the race, the traffic and bumping going into the first turn, acting up in the holding barn, missing four days of training, possibly being dehydrated, sweating between his legs and not much on his body, breaking awkwardly, possibly getting spooked by the starter in a blue jacket and white pants standing right on the racetrack,? It likely was a combination of occurrences that led to his shocking performance.
