If you're developing gyno then I'd get some raloxifene asap. Also, use the letro to help control the estrogen but i'd start off at .25mg eod or e3d.
I agree on this letro Dose 100%. I have seen way too many people take way too much in a rush to try ride gyno and end up causing them selves more issues.
And I agree with the SERM use while starting the AI. block what you can while waiting for AI effects.
