I use this
Optimum Natural 100% Whey Gold Standard (chocolate). It is rated one of the best in the market. I bought it from GNC and I found a 20% coupon for the store online. It came out to be pretty reasonable priced. Amazon also carries is.
All whey proteins, IMO, have a smell and taste problem and some more than others. I also tried ProCell and I gagged from the smell. Optimum protein, also has a smell, but it is less overwhelming and it has very less aftertaste. I have used it in plain water and in shakes/smoothies. I can tolerate this one.
There are lots of protein powders available now in the market, make sure you do your research. A lot of them have added crap or sugars which IMO defeats the purpose.
