They give you measuring sticks with each package. I just bought 100 servings of everything I wanted and combined it in a big container and shook it the fuck up. It was a little strong so I added some flavored bcaa powder to water it down. It's alright now.
Seriously 5 grams of caffeine? You would have to be a moron to take 5 grams. I just take a little less than an 1/8 of a teaspoon about 300 mgs pretty simple. Of course it all depends on the serving size.
