While ’s can be used in either the prevention or reversal of gyno symptoms, they are best employed as a preventative measure…and with good reason. You see, the job of an . is to prevent testosterone from aromatizing into estrogen, which it does very well, but the problem is that it does absolutely nothing to prevent currently circulating estrogen from continuing to cause problems. As long as ’s are utilized as a preventative measure and not for the treatment of an emergency situation, they are preferable to other gyno remedies, but that is not all. The primary mechanism by which ’s inhibit gyno formation (management of systematic estrogen) also provides numerous other benefits not found elsewhere, such as: reduced water retention, lowered blood pressure, decreased fat storage, and others. Lastly, .’ do not reduce IGF-1 levels, as will tamoxifen (Nolvadex).
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.
