Surgery is the preferred treatment of choice
1. I read your query. I am happy to help you. You mentioned that there is a lot of fat under your nipples.
2. You already taken zinc tablets to reduce estrogen
release and also done fitness by doing jim so that you reduced your weigth from 84kg to 74kg but still no change in your boobs size
3. The best treatment of choice is by doing surgery for gynecomastia
which reduce the fat under the nipples
