Has anyone used either of these?
The IsoXP has about 45g of protein per serving compared to 23g per serving in the Prostar Whey but the Prostar Whey has extra amino acids in it that I havn't seen on the label for the IsoXP.
Does anyone have any input?
I wanted to get the ON 100% Whey at first but the guy at the store said Ultimate Nutrition was better.
