Those are worthy goals; but other than HRT, you can’t make significant changes to your body. Supplements give some results for some people, but are totally unreliable. My prostate medication, and perhaps soy milk, gave me modest breasts, but none of the supplements I tried made any real difference. Shapewear, padding and breast forms can create a good illusion, and the right clothing choices will also help a lot. Good luck with your quest.
