GYNO IS NOT THE ONLY CONCERN IN SIDE EFFECTS
other side effects include lethargy, suppressed gains, suppressed sex drive, acne, bloating and mood swings
just because you are not "gyno sensitive" doesn't mean you are not "lethargy, suppressed gains, suppressed sex drive, acne, bloating and mood swing" sensitive
also, each of these side effects can be caused be EITHER elevated estrogen (high rate of aromatization from testosterone, dbol, ec...) OR overstimulated progesterone receptors (stimulated by drol, tren, nando/deca etc...) or a combination of both
