I read a few reviews before ordering this product complaining that the container was not filled completely or that there were only x number of scoops in the bottle when there should be 41. I wanted to make sure I was getting what I paid for and weighed a scoop. The serving size per the bottle is an 11 gram scoop. A full level scoop weighs about 14 grams (not including weight of the scooper itself). To ensure that you get all 41 servings from the container make sure you are not using a level scoop each time, rather leave a little room at the top of the scooper - about 80% full.
The specific review I saw stated they measured out 32 servings from their brand new jug, rather than 41. If level scoops had been used in this experiment, assuming an additional 3 grams per scoop means there was 96 extra grams of product used (32 scoops x 3 grams per scoop of overfill). 96 grams of extra divided by the 11 gram serving size is almost 9 additional servings (96/11 = 8.72). So the 32 scoops that were measured plus the 9 they would have had if each scoop was 11 grams exactly would have been 41 scoops total, the exact amount that is stated on the jar itself.
I hope this helps anyone else out there that is concerned about getting what they pay for :)
