Is ISO SURGE considered to be lactose-free?

If your stomach can handle 1/20th to 1/10th of a glass of milk, then your stomach can likely tolerate a scoop of a typical whey isolate. That small amount of milk, and a scoop of whey isolate, both contain about the same small amount of lactose. No whey protein isolate is absolutely 100.0% lactose-free, but many people who are lactose intolerant to a glass of milk, for example, can handle whey isolate.
