60 mg raloxifene, 2.5 mg letro, and 50 mg proviron per day will be your best shot at reducing it through drugs. It can take time so don't expect a full reversal in 30 days. You will be looking at months if you want to see significant shrinkage. Surgery is your only 100% guaranteed option.
I would recommend taking 5-7 of that $100K and getting the surgery from a reputable surgeon.
