Been on ON (Optimum Nutrition) for a few months. Easy on stomach, mixes with a spoon and no clumps, will have to do a break down on protein per weight. Its very recommended for price.
Order by the 5lb jug on Amazon $57 last me 5 weeks, free shipping.
I saw it for $50 and ordered that one thinking it was a sale. I didn't see it said Whey Supplement, was more of a diet protein with less grams per serving.
Currently have Double Chocolate something. It's good but not near as good as the Chocolate Ice Cream.
Mocha Cappuccino was great too
