HeavyIron, I know DMZ is Little to no progestenic/estrogenic activity but what about m-sten? IML states it has, M-Sten also lacks the ability to aromatize to any degree, nor is it capable of 5a-reduction. So does all this mean it has as much estrogen conversion as halo or cyano? I had no issues with those two. Is amex or nolva needed with something like this if they are gyno prone?
