just because it does not affect you that way, does not mean that its not an issue for others. Though its always easy to say, does not happen to me, until it does. Take for example tren and deca, you always see people saying- never had any problems, sex drive is through the roof... until some cycles later... they cant get it up when taking nandrolone or tren... or they get gyno.
never had any problems, does not mean that it cant happen.
though its clear that nolva DOES not have libido impairing effects on everyone, its probably a number somewhere less than half.
