I'm getting the side effects!!!

I think it actually depends. Gyno is surprisingly common and i think it really depends on one's sensitivity to estradiol (number of receptors in breast tissue). Luckily it seems it's not permanent if treated as soon as you get the early symptoms: swollen nipple, pain.

Out of curiosity, did you libido increase after you started the therapy?

Edit: Also, let's not forget an estrogen excess in men causes prostate cancer!
