i don't see any benefit in taking nolva EOD while "on";i had some gyno symptoms from dbol and used nolva for 4 days str8 and totally got rid of the problem...i seized the dbol,continued mu sust and i am 100% gyno free...nolva is very hard on the liver and should be used only when necessary...oh!and i was using 20mg ED for 4 days to combat the symptoms...hope this helps bro.
