Prescribed spironolactone

So I was wanting to go on accutane however my GP doctor said my acne wasn't severe enough... ive already been on epiduo cream and lymecycline for over 6 months now and wanting something stronger, I asked for an alternative to accutane and he suggested spironolactone starting on a 50mg dose... he mentioned that I might have a lower sex drive and feel less motivated ect because it reduces testosterone which tbh I thought i would get away with considering im 20 years old and already have high testosterone, however after doing research into this drug im actually concerned as apparently its used as a transitioning drug for trans people and also the fact that it can cause enlargement of breasts and that it completely blocks testosterone.

Does anyone have any advice on this and maybe if theres something I can take other than spironolactone?
