Only way is to get surgery.
Dont listen to this. He isn't completely informed. That was true BEFORE the real good anti-estrogens(Aromatase inhibitors) were invented. I became an expert on anti-estrogens
thru my own experiences. The best anti-estrogen for shrinking the breast tissue is LETROZOLE. You can order at at
www.pumpnpose.com It will be shipped to your home within a couple days from Georgia.
It IS NOT a controlled substance like a steroid is, so there is not much risk.
You will be purchasing it from a research company-under the auspices that
you will be "conducting research" with it (completely legal)
It has been proven to actually reverse gynocomastia. I had mine removed surgically
in 1992, and it left funny looking "creases" in my skin. Surgery is the LAST RESORT.
I had no choice back then because this stuff became available circa 2000. After the size of the cyst has shrunk, surgery may be needed if it cannot completely dissolve it.
If the LETROZOLE doesn't work, then you will need surgery.
