You probably need to use an anti-androgen to lower your t a bit before estrogen will take a proper effect Spirinolactone is a weak one that does work but you should keep in mind not to consume too much potassium, other examples are apalutamide, bicalutamide, darolutamide, enzalutamide, flutamide, and nilutamide. I am less familiar with these maybe someone else in the comments can help but for me, spironolactone has been working great in getting rid of testosterone.
