My tokyo testonon bottles look 1/2 full. They are supposed to have 1250 mgs. I have been drawing around 1100 to 1150 as you will lose some every time you draw and there is always a small bit at the end I can not get out. My adivice, you should always overestimate a bit to be sure you have enough to meet your goals. I think AJC posted something on this last week as well.
