• People copy the dietary practices of pro bodybuilders on androgens. Steroids enable you to assimilate far more protein than you’d normally could.
• People based their recommendations on the flawed nitrogen balance studies back from when the world was still flat.
• The more is better heuristic. There are so many studies showing protein is good for you, it’s hard not to think more of it is even better.
• Supplement companies have an obvious financial incentive to make you want to believe you need more protein than you really do. There are actually several industry-sponsored studies showing absolutely miraculous benefits of consuming more protein (see for example the studies by Cribb).
• People can’t be bothered with decimals and just round up to the nearest convenient integer, which so happens to be an easy to remember 1.
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.
