If these figures are all based on proprietary blends, how can you know that the size of that blend relates directly to it's effectiveness or value? If you don't know the amount of each ingredient in the blend, then how can you compare them by serving size.
I don't really think there is a perfect way to compare these. Maybe by judging how many scoops of each product it takes to give you personally a similar effect, then divide the price by that number.
Please clarify if I'm not understanding something.
Well essentially you can't really know at the end of the day, but I think the larger the blend the more likely they are at least accurately dosed. (Probably another reason you need like 3 scoops of jack3d for anything.)
