If you have started to get gyno and I presume you have otherwise you would,nt be taking it I would still run it throughout the cycle.You,ll still make gains and if it is the choice between big gains with gyno Vs avg gains without gyno I,d go for the latter everytime.You could run the Arimdex to help rduce bloating but if not I would,nt bother just run the Nolva @ 10mg if the symptoms have subsided JMO
