thought i would share my progress w/ letro on pre-existing gyno. im on my 5th day and im at 2.5mg right now. i did some HIT training while hiking early saturday morning (took my 2.5 letro before hand) and by the time i finished the 8mi hike, i swear my gyno had gotten smaller. i still get hard in the morning, but no drive. i think i pulled something yesterday while hiking so beneath my right knee hurts like hell (i don't know if this is the joint pain people complain about). other than that, its going well. i was wondering though, does smoking ****hinder the effects of letro? or wouldn't matter since letro is so strong? any comments/replys would be appreciated! thanks!
