but there is a huge difference in wheys. Allot of wheys are full of fillers and bullshit cheap proteins and junk then they charge 70$ and call it a blend. Look at syntha 6 for instance locally 60+ for 5lbs BB.com 50$ for 5lbs...
47.2g of powder per serving with only 22g of protein per serving? thats crap, taste great sure and the first ingredient is Whey Protein Concentrate, then whey isolate. So you actually HAVE no clue whats in their "protein matrix" for all we know its 90% concentrate and fillers to make it taste good.
Now you look at dymatize iso 100 hydrolyzed... 70$ for 5lbs but 31g per 25g of protein (looking better), only ingredient is hydrolyzed Whey Iso for protein so you know your getting a quality protein.
I personally only take truenutrition Whey Protein Isolate Microfiltrated, which is 30g per 27g of protein and has an outstanding amino acid profile. for 60$ for 75 servings. Does not taste as great so the other brands with fillers but who cares about taste it taste good enough. I want gains.
