It's good to look at the ingredients in VP2 and find that it does have what it says it has on the label which says "Whey Protein Isolate" (Hydro). What a lot of companies do is put these words on the front of their labels hoping that the newbie won't bother to look at the ingredients to find that it is a blend with WPC and other forms of whey so thumbs up to VP2 there.
The protein percentage is a little concerning though, especially being something as pure as a Hydrolyzed WPI. At 23.5g of protein per 28 gram serve, this is just a little under 84% of protein you are getting in the whole product.
For comparisons sake, our Hydrolyzed WPI is 90% Protein.
Just to further give you an idea of the savings that can be made here, a 908g tub (who makes up these tub sizes? lol) can be purchased for around $65.
A 1kg bag of Bulk Nutrients Hydro WPI can be bought for $49.
More for less, really.
