Hi,
I'm sure there are options besides the invasive, scar-inducing, painful and not least expensive surgery route.
Letrozole is a breastcancer drug that is known to be able to reverse gyno to some extent, beware of the side effects of low estrogen and the rebound risk when stopping the drug. The latter can be remedied by finishing a period of medication using the suicidal aromatase inhibitor Exemestane.
Other aromatase inhibitors as well as SERMs (selective estrogen receptor modulators) that are milder can work to some extent especially as part of a treatment or to stop further growth.
The most interesting treatment and the one I'm currently using together with a very mild oral dose of an aromatase inhibitor is topical DHT (Dihydrotestosterone) dissolved in an alcohol carrier and mixed with a little pure DMSO to promote absorption, this is rubbed around the nipple area daily to twice a day.
This treatment is working remarkably well and has removed about 90% of my gyno in just over 2 months of treatment.
To say things like you wouldn't want to shake someone's hand that rubs these compounds on themselves as I have heard here is just absolutely ridiculous when elderely and testosterone deficient men get andro gel to rub on themselves all the time as prescribed by their doctor.
I use a nitrile rubber glove to administer and rinsing the solution of skin or glove with normal water and soap is no problem at all.
Unfortunately most doctors and medical companies are only interested in promoting medical solutions that generate money, solutions that can't be patented and/or are to cheap or effective are disregarded as humbug or illegal due to the fact that nobody spent millions getting them approved.
It does not and should not stop you from making your own research and making your own informed decisions to remedy your own problems.
However be sure not to rush this procedure since you will yourself be responsible for anything that you overlook.
For example if you are prone to male pattern hair-loss perhaps you need to consider another treatment for this at the same time if you decide to administer DHT in any form.
I use minoxidil and topical finasteride as well as topical spironolactone on my scalp for this.
It is surgery, or live with it!
