Slang for Estradiol which is a pill that is taken by transgender women which causes breast growth among other things. One common variety of it comes in the form of a green pill which has a minty flavor, hence the term breast mints.

Spironolactone, which blocks testosterone, may also come in a minty form although there are also very bitter forms of it.
My doctor just prescribed me breast mints and I am such a happy girl!

Random person: Which pill did you just put in your mouth?
Transgirl: Breast mints.
