My two cents. I used letro first, for unilateral gyno, that had an onset after using a product that most people swore was bunk or was akin to buying expensive vitamins. No reduction. I used Arimidex, no abatement. The other nipple started getting sore. I went to toremifene. Within two days of utilizing at 2 ml of 60mg strength, no more tenderness, libido increase, reduction of hardness, although not necessarily of the size. I cannot see it after a good chest workout, and only see a puffier nipple in the morning. I am now using ralox 50mg strength and even remote tenderness is gone, although the much more diffuse lump is present about nickel size.
Keep trying. I don't want to split hairs about you can't obliterate it, you can't reverse it, its gland tissue, its fatty, its set in, etc. Mostly this is people that have never had gyno, or have "read" about gyno mostly from other posts of bro science. If one can shrink it to nothing, have a good contour of the chest, not feel sore and sensitive at the nipple, I say its gone. Also complete BS about too much masturbation, not enough test production, pesticides, etc. Some bro sciencer was trying to educate me on the difference between testicular atrophy due to test supplementation vs. gland tissue in the nipple, how pubertal gyno can disappear but AAS cannot. See an endocrinologist, keep up the good fight, use torem, or ralox, use letro, take zinc, cut off a chicken head and poke pins into a doll. Do everything, and then see if the offense is too much, and surgery is the out. People that have never dealt with it stay out of the fray.
