One of my girlfriends took these natural meds for a few years before she was able to get real hormones. Her opinion is that she feels like they worked, but never noticed anything in particular. And she took these, I believe, prior to when she was 18. I'm doubtful these will do much for you. If you are looking for hormones, there are better ways.
I'm terrified of injections myself, so I go the pill route. It's been working for me. Let me know if you have any other questions.
