I had it before breast cancer diagnosis and had to come off everything, (though one consultant said it's how they used to treat bc?!)
It did work. I only needed a half dose. It went to high, libido was actually unpleasantly high and my hair fell out. (It did recover)
Women MUST be within female range and tested regularly.
However, I've since learnt about the impact of building lean muscle mass. Same consultant agreed that me doing this would impact my testosterone levels. And I do now feel the same confidence that I had while I was on testosterone, despite taking tamoxifen.
Lean muscle mass / resistance training and more protein and the right sort of carbs at the right time to help build muscles, is also thought to reduce hot sweats. I'm finding it does work for me.
