I am experiencing delayed gyno from mass tabs started letro according to c bino's routine. I have read in a profile that letro takes 60 days to stabilize most feel only 2 weeks. I also read that 2.5mg's should not be run for more than two weeks and then u should begin the taper. Others say to stay @ 2.5until lump is gone. I am interested to find out how long u guys have been on 2.5 mg's until symptoms were gone
