I have just been taking it for a little over a week, and do believe it is beginning to have its effect. My stamina is stronger, and am able to get more things accomplished in a day. I still have to be careful about not over doing it. When I am feeling good, it is easy to get carried away with the schedule, but I do see definite improvement.

"Bravo! All four bottles of the Carao arrived today.  I admit I waited far too long before re-ordering. When I did send the order in on September 28, it was with some trepidation simply because of the difficulty of the first order finding Denver, Colorado. But now in slightly a little over two weeks, the entire order arrived.Thank you. From the time I was without it, I could definitely tell the difference in energy level. Next time I definitely won't wait so long."  Thank you for your quick response.  Holly Denver, CO
