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. 
In general, Proviron is a relatively inexpensive and easily located product to find. Pharmaceutical grade Proviron is always going to be more expensive than the underground counterpart, but that is the way things go for almost all pharmaceutical products versus UGL-manufactured items. Schering Proviron in particular sells, on average, for around $ per tablet (25mg). Other pharmaceutical brands of Proviron can be lower priced, with some ranging around $ per tablet. Underground grade Proviron is known to be much cheaper for obvious reasons, with some being sold for as low as $ per tablet (25mg). Underground products are not manufactured to any standard, however, and some brands may manufacture tablets in different concentrations (20mg, 25mg, 50mg, or even 100mg), and so it can become quite difficult to gauge and judge current market prices because of this.
