I was going to start a new thread but I'm too new here. Topical letrozole may work for you.
I'm thinking this could be very useful for gyno, or gyno prevention and to avoid the systemic side effects on blood lipids, sex drive, possibly igf levels and reduced gains that some people report when using with steroids.
"As expected, the local tissue disposition studies revealed that compared with oral administration, transdermal administration could produce high local drug concentrations and low circulating drug concentrations and reduce systemic side effects. Therefore, it is a new option for breast cancer therapy to inhibit aromatase activity via the transdermal patches for site-specific delivery of letrozole".
"These findings show that letrozole transdermal patch is an appropriate delivery system for application to the breast tumor region for site-specific drug delivery to obtain a high local drug concentration and low circulating drug concentrations avoiding the risk of systemic side effects"
I can't post links so here is the title for anyone to google to see the study.

I don't have gyno and am not on anything so can't try but I bet it's worth a shot.
