Generally women that suffer from low test levels will be given an androgen replacement cream or a patch, such as androgel or androderm. This way the test levels are easily controlled because of the fast acting nature of transdermal testosterone. Also there is no need for constant injections, therefore the HRT is very comfortable and safe. Like I said, that is typically what a doctor will give a female if she needs extra test in her system. Unless she is looking to build muscle testosterone injections are a bad idea. Besides that women should never use long test esters like cypionate, enanthate, or deconate like in sustanon. There is just too much risk with virilization. Hope that helped.
