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 you suffer from plantar fasciitis, you might think perhaps you should rest your feet, but it’s actually better for you to keep on the move. Plantar fasciitis affects the band of tissue connecting your heel bone to your toes, and can cause stabbing pains when walking. A treatment for it is to keep moving, but make sure you don’t overdo it. Keep your mileage and speed down if you begin experiencing pain, and place an ice pack under your foot for 15 minutes after you’ve finished walking. An alternative is to roll a frozen bottle of water under your foot for 10 to 15 minutes instead. Adding support to your foot can also help, so using an insole in your shoe or wrapping your foot with athletic tape is also recommended.
