What's a scoop?

After looking at several protein powder containers, it seems they all suggest one or two scoops to be added to whatever mix you're using.  My question is 'What's a scoop?'  They don't seem to have a measuring device in the containers, so is a scoop a half cup, two teaspoons, or what?  All answers appreciated.

All the ones I've ever bought had a scoop inside the container and I couldn't begin to guess, since I don't know what brands you are using and have checked. If there is no scoop inside, I would call the company's customer service line and ask (or check their website, if they have one).

Most scoops are down in the bottom, due to settling when they were shipped.  I take a long knife and sort of fi**** out.

I lost the scoop to one of the big bags of protein powder I had (EAS Premium Protein Blend) so I used the other scoop, and this is what it is for that brand anyway:  a scoop was 1/4 cup. The protein powder should have information in the nutritional info section.  My bag says "serving size:  2 scoops (35 gr)" but grams are a weight measurement and cups are a volume measurement, so I guess there is no way to tell unless you HAVE the scoop to measure with.  So in my case I wrote 2 scoops = 1/2 cup in marker on the bag in case I lost the scoop again!!!

Thanks for the responses.  You were right, I dug down into the powder in the opaque plastic bottle, and sure enough there was the scoop.  Put it down to me being a man and not checking before I called for help.

LOL hey dont worry, I thot the same thing when I recently opened my bag of protein powder....I then started digging for it...but for awhile, I was really aggravated thinking I would have no idea how much a sccop was...im sure there have been mistakes and the scoop has been left out...they should give the actual measurement on all containers for this reason.
