I have been taking this product less than a month and have noted a small difference in the "Before & After" comparison. I seem to have slightly more stamina and increased energy, but at 73 years old, I am being very cautious in drawing any conclusions as of yet. My second order is in the mail now, and I feel more confident that it will prove to be even more telling as the residual momentum begins to build in my metabolism.
I will give it 4 stars, at this point; and, withhold "recommendations" for another month.
