Has anyone used Maca?

Hi guys;

In the last two years I've lost a lot of weight, and have been on the pill since I was 12 (due to the PCOS)- I've just recently stopped taking the pill and have started taking Maca as I've read it can help in balancing and regulating hormones, and energy; and I want to find out how my body is functioning, and what that chances are like now of hubby and I trying for a bub- I'm not getting my hopes up, and just trying to get my body stable.

It's helping me for energy; the rest it's yet to be determined by a few blood tests by my GP in about 6 weeks. Just wondering if anyone has any pros or cons.. or experiences they'd like to share about Maca?
