i've been trying for a year or so now and have had no luck...i've tried letro, nolva, praying lol....it feels like i have two or three marbles under my nipple area...haven't done any aas since nov. of 2010 (besides this 3 week sus250 cycle i just cut off do to some lower back pain and my gyno flaring up again)...should i hop on letro again? if so how much should i take? i've taken up to 1.75mg eod for a few weeks and saw some results but as soon as i stopped it came back!
