Not shortly after Roger Maris record was broken, another baseball player, Jason Giambi and various other athletes were either suspected of, or proven to have, taken anabolic steroids. Again, Congress convened a hearing, and just as they did the first time in 1990, they did not determine that steroids were a danger, but rather that the danger was more in protecting professional sports organizations. The updated statute has been updated to proscribe pro-hormones also The definition of an anabolic steroid as defined currently in the United States under (41)(A) is that "anabolic steroid" means any drug or hormonal substance, chemically and pharmacologically related to testosterone (other than estrogens , progestins, corticosteroids, and dehydroepiandrosterone (7).
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 Roid Calculator
calculates the estimated blood level of different steroids, using half-lifes.
The half-life is simply the time when 100 active milligrams breaks down
to 50 active milligrams, to 25 active milligrams, and so on. The half-life
may come after a few days, or a few hours, depending on the drug.
You can use it to see how much active medicines you really have in your blood.
Please remember that the results are only approximate.
The half-lifes used below is based on several scientific studies.
Most of these studies used the glutes as injection site , if you inject in the delta muscle you will have much longer half-lives, try doubling all half-lives.
