The general consensus seems to be that they are total CRAP. Seriously I'm not joking. Also, isn't the main ingredient androstenedione? If it is, even if it worked, you wouldn't want it. There are much better prohormones available, like 1-androstenediol and 4-androstenediol. Also there are the nandrolone precursors, stick with the diols as well (norandrodiol not dione)
The dione's carry harsher side effects than the diol's and are generally thought to be less effective.
