Transdermal is a very viable form of delivery for hormones that have poor oral bioavailability. Transdermals have been used for years with great success. Granted, you need to use more hormone due to dismal absorption rates but the cost of non-estered base hormones is usually much less than estered counterparts and offsets any issue.
Do not use alcohol based carriers. Do not applly alcohol to areas. Alcohol only servesd to dry area which will in turn decrease absorption. Apply in areas that have ample blood flow...inside forearms, clavicle, calves, inner thigh.
I haven't been on forum in a while but I have played with transdermals and had excellent results.
