I've tried a few brands, including the one that Costco sells and all of them have such a terrible taste. But lately I've done some research on the best tasting whey and it seems that everyone is touting that their's is the best in taste. I've narrowed it done to a few brands that seem to have good reviews and selection of flavors. I like to know if any of u had tried any of these whey products and/or if there are other whey that u would recommend. http://www.luckyvitamin.com/733739021625.html http://www.worldclassnutrition.com/worldclassnutrition/ecdelwhey2lb.html http://www.wholesalesupplementstore.com/protein-delite.html http://www.bodybuilding.com/store/pvl/whey.html Also, has anyone tried Spirulina? http://www.getnutri.com/productdetail.asp?pid=23981 I'm avoiding Soy protein due to reports of them possessing plant estrogens.
