Query: Hair Formula 37 Vitamins

I have been taking these for a couple weeks now and in my opinion, they are just EXPENSIVE GARBAGE! I wasted my money, so don't waste yours. I like my Utra Mega Vitamins from GNC, much better..They also work better as far as hair and nails. I will never buy Hair Formula 37 again
