50% more servings means the original # of servings per tub was 10 if it is now at 15.
I was not aware of the 'more servings' note.
And if adding a few TBSP of yogurt qualifies as 'prep time' for you, I have to question how you go about your nutrition in general. No offense
Personally, I think Metabolic Drive Complete has a better consistency and is sweeter because there are more carbs. However, I bet a little xantham gum and some greek yogurt from Trader Joe's would be good with Low-Carb Metabolic Drive.
