A:  Formadrol® is an ingredient that works by blocking the 5-alpha-reductase enzyme which blocks SHBG by blocking estrogen. Still with me? Blocking estrogen is exactly how you "free up" testosterone. Formadrol® does this like no other over the counter supplement because in Europe it is actually a prescription drug (Lentaron) and it's used to treat women with breast cancer. For those women who took Lentaron during clinical trials, it was noticed that they began suffering from a side-effect that troubled everyone so much, the trials were stopped. That terrible side effect was that women were becoming too muscular. It's such a potent estrogen blocker, it actually freed up the minute doses of testosterone that women’s bodies produce.  Super-charging your testosterone production with AAS or prohormones, and then protecting yourself and freeing yourself up even more with Formadrol, means that you can approximate a cycle like Sustanon and Cypionate - more mildly of course - and not get any of the sides.
