Checkout the profile of this product and then use it
I've ordered a couple of containers and it does produce results, should notice a difference after 2 weeks of usage.  The profile is pretty good and you'd be extremely hard pressed to beat the price for what you get.  Also, the taste is not bad at all, pretty decent.  I use the non-caffeinated version and this is one of my staple supplements.  Note, I did not receive anything for writing this review.
