they have good price for WPI but as I can see in nutrition info of their WPI in one scoop there is 1g of carbs ( possibly lactose ) , only that can be a problem , only way you can find out can you use allthewhey WPI is to try it , it depends on your level of intolerance , also good thing about allthewhey is that they have auctions on e-bay
I'm also lactose intolerant , and I tried trueprotein.com and proteinfactory.com WPI , and I don't have problem with them , but didn't try from allthewhey WPI , so I recommend you to order WPI allthewhey 2lb and see can you use it
