Walmart huh? Hmmm . . I get a little sketchy buying something like this from anywhere other than a health and fitness association. It might be o.k. but I usually like to purchase items with a brand name I have heard of before but if it's really cheap go for it!
Don't diss Weider Products man, weider has a huge processing plant, and they manufacture, protein, creatine, and glutamine for many reputable companies.
