Since Testosterone is a natural male hormone, so female’s application of testosterone pills is probably couses the development of male secondary sex characteristics. Therefore we advise women to pay attention to this fact and to exclude any types of testosterone and other androgens (like Anadrol, Dianabol, Trenbolone,…) from the application. Low virilization risk (female) steroids are: Anavar, Primobolan, Winstrol, Masteron.
