is estradiol valerate any good for DIYing?

hey :D my partner (AMAB, nonbinary) is looking into transitioning but is aiming for kind of an androgynous appearance, and as we're in the UK public healthcare options are pretty shit, especially since they're not out in most areas of their life. we're looking at some options for DIYing, and one of the things they're considering is taking Progynova (Estradiol Valerate) tablets (2mg/tablet, normally prescribed for menopause). does anyone have any experience/advice with this taken by itself?
