Dosing is almost always dependent on the user. Do some research to figure out typical doses. The labels speak nothing of dosing protocols...that's not really NP's responsibility. If NP were to supply scoopers with each bulk powder they carry, they would have to stock a bajillion different size scoops. It's just as easy to use measuring utensils from your kitchen.
In your case:
Leucine will be in the range of a few grams per dose. But if you know what Leucine is, you should be able to figure out how much you want to supplement with at each dose.
And if you know what Waxy Maize is (a carb), you should figure out how much you want to use in your post w/o shakes. ie if you want 40g of carbs in your shake then calculate how many tablespoons equate to 40 grams of Waxy Maize.
