For those interested in wether or not letro will kill off any and all existing gyno, well I wanted to post this to give you guys a heads up. I've had gyno about the size of a quarter on the left side of my chest since my freshmen year in highschool. Now I've used estro killers in the past to keep flare ups down and to prevent it but have never had any sort of reduction in existing fiberous tissue...til now. Since I've been one, about the 3rd week into it I started to get sore and puffy. Felt around and sure enough, gyno was setting in again around the existing tissue. I started taking letro at 1.25mg EOD to help reduce estrogen in my system but HOPEFULLY not enough to supress all estrogen gains from the test and deca. Well this would be my second week using it, and not only has the cycle induced gyno been knocked out, but the old stuff has started to become less noticable and has an obvious palpable reduction in overall size. I'm going to stay on it for another week or so pending how I feel on it and come back down off it to get me back in the testo/estro way of things while on unless I have another flare up. Once the cycle is over, I plan to run letro with HCG and igf. So when it comes down to it, letro, in MY case, has actually destroyed a noticable amount of existing gyno tissue in a matter of two weeks on an EOD dose. Now I'm told 2.5mg a day is recommended to remove gyno but I haven't needed such a dose to thsi point and won't ramp it up until I stop progressing. Any and all updates about how it's going I'll just post here in this thread. Anyone else have any letro experiences?
