well, I certainly don't 'swap' the scoops, I always weigh them when I first open the bottle. I'm also looking for an exact amount of protein, not just the biggest scoop in my collection.
For example: I want 50 grams of protein in my post-workout shake. The protein I just bought says that each scoop is 30 grams with 21 grams of protein (not the best, I know).
So with these figures, I need to put two whole scoops and about a third of another scoop to get about 50 grams of whey. BUT, when I weighed the scoop, it weighs 9 grams, and the powder that fits in the scoop is only 21 grams.
SO, if I wasn't so obsessive and just trusted the nutritional info, putting 2 1/3 scoops would only give me about 34.3 grams of protein in my shake, in effect depriving me of almost a THIRD of my protein after EVERY
WORKOUT that I would use this particular protein, not to mention the other times in the day that I may want to take it.
Not only in proteins have I seen this, but also in glutamines, creatines, and creatine mixes as well.
Hell, I just weighed some AA pills that I have, it says 4 is 6 grams, but they weigh 9!!!
And no, my scale is not broken.
I hope somebody else tries this and lets me know what they think
