Estradiol wouldn't have any downsides for me if it didn't change your physique. It increases the amount of fat on the thighs and legs, and this is a disgusting effect.
At the same time, the negative effects of testosterone can be neutralized by taking Bicalutamide. Baldness is the hardest thing to counteract, I will try to do it with RU. Overall, you are greatly exaggerating. Testosterone is clearly overrated and considered the source of everything good in a person (many people are concerned with how to increase it and see its deficiency as the cause of all problems), but considering it total evil is also not correct.
