This is what will happen to your body if you only take Testosterone Blockers without supplementing it with estrogen.
Taking anti-androgens without taking estrogen would block the effects of testosterone.
With full HRT, a trans woman has to take both anti-androgens and estrogen in order to mimic female hormone levels.
Estrogen without anti-androgens will be much less effective as the testosterone will still be present to the levels of a biological male and competing with the estrogen. Thus the benefits of estrogen. i.e. breast growth will be severely negated.
However, if one does the opposite, and only takes the anti-androgens, a number of noticeable changes might still occur.
First, because the testosterone production will be inhibited, many who take anti-androgens report feeling less “edgy” and more relaxed (as a side note: spironolactone has been used to treat hypertension.)
After a period of a few weeks, your libido will diminish, as will your ability to gain and maintain erections. Over a period of 6 months or so, you may notice that body hair becomes lighter.
All of this, of course, depends on your metabolism. Remember to see a doctor for regular blood work. Certain anti-androgens can have negative effects on liver function if taken in higher doses and/or over a long period of time.
Also, be sure to drink water, as many also have a diuretic effect.
Want a massive hangover? Drink a few glasses of wine while on these and don’t rehydrate. Your head will hate you in the morning.
