Well, they had a special offer on their website for a free months supply ($5 shipping). I figured I'd try it.
Almost two weeks in, and I can't say as I've seen any significant improvement.
Truthfully, it's doing no harm. It's basically an herbal suppliment with niacin, zinc, copper and ginseng. And some more stuff. And I think that under a lot of circumstances it might help, but for me so far, nada.
