Hello, I have not used it personally as have ER and PR positive BC and on aromatase inhibitors. The issue with testosterone is it converts to estrogen so not for me. Before my diagnosis I used estradiol and testosterone pellets and felt wonderful.
Know that here in US you can get testosterone and Anastrazole pellet in one and some use it and data looks promising but need large trials. Not FDA approved though. I have an GYN Dr who talked to me about it as she did my pellets before my BC but I talked to my medical oncologist and he was hesitant as he said he did not know how much of the testosterone would aromatase into estrogen so the answer was a no for me.
I felt great on testosterone and estrogen before diagnosis too.
I was more gutted about giving up my HRT than anything else, so even if there a small slither of a chance of getting some quality of life back, I'd take it.
