I'm assuming the scoop that comes in the Biotest creatine is equivalent to 1.5 teaspoons. Correct?
I havent checked, but I imagine fillin up the Biotest scoop and then dumping it into 1.5 teaspoons will give you the answer you seek.
Here is a more fun way of figuring this out. Take a whole container, which has 100 servings, and start scooping. If you count 100 scoops in the container, that means the scoop is the 5 gram serving, or 1.5 teaspoons.
How come I didn't think of this myself?????!!
Weigh it on a scale. Zero the scale with a small container, then add 5 scoops. Take the average, and you have your answer...
You must have done this before...with creatine of course.
