Substance: Testosterone (17-beta hydroxyandrost-4-en-3-one)

Androderm is a transdermal patch, designed to release testosterone over a 24-hour period, in a natural pattern resembling that of a health young man. Androderm is being used primarily by older men who have reached an age in which their body no longer produces sufficient amounts of testosterone (”Andropause”). Each patch contains 12.2gm of testosterone, but according to the paperwork only about 2.5mg is dispersed in each 24-hour application. Two patches are most commonly used, and are applied to either to abdomen, back, thigh or upper arm. Athletes would no doubt find this dosage insufficient. Quite a number of Androderm patches would have to be used for a strong effect.
