Hi wee2er,
I will ask about the gel and patch, needles don't bother me so all the options besides oral are open to me.
My last labs while taking estradiol: estradiol 30.9 and testosterone 552. Both within normal range for an adult male, she will probably do labs next week just to see where everything is at, and get a good baseline.
So far the only unwanted effect from discontinued estradiol is my leg and arm pit hair grows back a little faster but my skin is still soft, breasts still seem to be rounding out, body fat hasn't shifted back to a male shape. However I was on BO for 2 years and there's anecdotal evidence that it flips a switch in some people that keeps them producing estrogen long after they stop, but nothing scientific, lol, I won't complain if it does work like that for me.
Thanks for the good advice.
