The label is NOT correct!!! Lucky Dog, from the AS and AF board weighed Supplement Direct's Dextrose with a digital scale and this is what he came up with- 1/4 cup=35 grams, 1/3 cup=47 grams, and 1/2 cup=70 grams.
A guy and I from the board reported the problem to them and they told me to use a digital scale to weigh it. While they basically told the other guy that they will change them when they felt like it.
