Whey Protein Company

Ok, lets do some math...hopefully my brain is still working

Kaizen has a $40 4.4lbs. tub of isolate at 85% protein per serving.
TS has a $35 5lbs. of blend (with main ingredient isolate) at 79% per serving.

So if you consider the ratios:

Kaizen - 4.4lbs. x 0.85 = 3.74lbs. of protein per unit
TS - 5lbs. x 0.79 = 3.95lbs. of protein per unit

Can you do this calculation but compare PROTEIN (g) per tub? What's in the remaining 20% could make the difference.
