Also forgot to tell you that on my 11.5 km run I ran it around 6 minutes quicker while I was taking the carao. It just sort of clicked the other day when I was trying to work out why I did better times a few weeks ago and not now. So that motivated me to send for another six bottles. Really appreciate your offer to upgrade my order. Will let you know what the results of my blood test are when I get it done in another couple of months. Fiona, Australia 8/2006
