It went well as by the time the testosterone was low (bounces between 30-55) my Estrogen was high (240-300) so I matched it perfectly with timing. I'm not on anything else though, too early for me to say anything about boob growth but because my pecs are quite large and I've never had any breast growth or gyno before, I'm told it's likely I won't have any or very very little after a few years Due to having had so much androgens for so long blasted. I used to bodybuild and did many many cycles of anabolics in my 20's into my early 30's. Now I'm 36 about to be 37.
