All the ones I have used, have come with a little scooper included. One scoop and a glass of milk is all it takes. The scooper is 29.5 grams(aprox. 2 inches across and 3 inches deep). You may want to dig around in your container to see if you can find it. It's very helpful.
If you cannot find the scooper, the protein usually takes up slightly over an inch of a full size glass. Sorry I don't have any proper measurements.
You owe it to yourself to be the best you can possible be - in baseball and in life.
A hot dog at the ball park is better than steak at the Ritz.
