Deca can and does aromatize. Aromatize means estrogen. It also has progestagenic effects. This is one of the reasons why some are against deca, because if you start developing gyno symptoms while on, you are fighting it from two different fronts. And that's not good since we still don't know what the hell causes gyno, we just guess at it and hope the nolva works.
